- FormatSpec is placed on "List's item adjusting" dialog and marked as
  "Specific". For AY-files "Offset" must be either 0 or valid offset to desired
  song

  same in Windows and Linux version now)

21 February 2016
- Precalculated in Windows 7 region is used now for all OS versions (including
  Linux) to avoid differencies in CreateRoundRectRgn for main window border

22 February 2016
- Lin: when playing AY/AYM CPC music, chip frequency is switching to CPC's
  1000000 Hz, but not showing in mixer current chip frequency field (fixed)
- Lin: fixed error of dropping folders on main window or playlist one. TODO:
  point of dropping files in playlist is not calculated properly yet
- Wrong reaction to missing bass libraries during calculating playlist time

- Revised code around pointers (too mach errors and warnings after moving from
  Delphi to Lazarus), in result was fixed some bugs in finder

9 March 2016
- Added updating tray icon hint and aystatus.txt after recieving BASS stream
  meta data tags (for internet radio, etc)
- Meta tags decoder is rebuilt for better decoding broken tags in some internet

  supported in theory)

15 March 2016
- Exceptions messages during adding files to playlist is collected and shown
  once after end of task
- Applied some tricks to load "damaged" YM-files with "xx-lh5-xx" marker like

  'YM Archive v5\DeMan.Joris (Scavenger)\Synergy Demo\Rapido3d_all.ym' and
  'YM Archive v5\DeMan.Joris (Scavenger)\Synergy Demo\Rapido3d_part1.ym'
  need to fix (truncated by header length)

16 March 2016
- Fixed TS-loader (continue loading as usual module if TS-identificator
  slightly different or has non-valid fields), need to fix 2nd module size
  in X-agon_of_Phantasy-Breath-of-air-6chan-MOD.sqt
- File analizer (finder) is switched off now during dropping folders and files
  on main or playlist window

v2.9 beta 16:
25 March 2016
- D2L: Used FPC resources instead of Lazarus resources
- Resources moved from RC-file to project properties
- Lin: WaveOutAPI.pas is not used in Linux version, and bug was masked here:
  AY visualisation buffer length was not set (in SetBuffer for waveOut) and
  visualisation was slightly earlier of sounding. Fixed.

28 March 2016
- If between Ay_Emul launching desktop size was changed and 'Save windows
  position' option is checked, some Ay_Emul windows can be 'shown' outside
  of desktop bounds. Fixed.
- BASS visualisation's AmpMin/AmpMax is in range [0.0001..0.02] now
- BASS connection parameters are added to Mixer->BASS 2.4 page (for Internet

  of non-Unicode encoding or if Unicode encoding is not autodetected)
- COMMENT and GENRE tags from CUE-sheet added to comment of playlist item now

6 April 2016
- D2L: tools (TL) button on main window was unpushed even if Tools window was
  shown (in Windows version only) due differencies between LCL and VCL (fixed)
- Added support for loading M3U8-playlists (M3U in UTF-8 encoding)

7 April 2016
- Tested in Windows 95 OSR 2 and in Windows 98 SE. Results: Windows 95 is not
  supported, Windows 98 is still supported. Next beta will be based on new
  FPC and Lazarus, which officially does not support Win9x anymore, so keep
  v2.9 beta 16 if you want to launch Ay_Emul in Ansi-based Windows (98/ME/etc)

v2.9 beta 17:
4 May 2016
- Starting migrating to Lazarus 1.6.0 + FPC 3.0.0 (Windows version ansi only
  code is changed to wide analogs, etc)

5 May 2016
- Wrong handling error if editor is not found during "Open in editor" (fixed)

7 May 2016
- Removed checking and other Ansi-branches code for old Ansi-based OSes (in
  Windows version), only Wide (Unicode) branches are kept
- From this point Win9x support is totally discontinued. LCL Ansi-branches code
  will be cleaned up in Lazarus 1.7.0 as expecting

10 May 2016
- Added codepage setting for "Track Descriptor"
- Removed FIDO-specific chars replacement (#205 and #240) from "Track
  Descriptor"

  exclude and only playlists

13 May 2016
- Mouse wheel scroll down causes playlist redrawing even if was no scrolling
  (fixed)
- Fixed TS-loader errors (wrong code if second module type is differ from
  filename extension; text fields for second module was loading from first one)
- For TS-files: second module text fields are decoded due selected code page
  now (for the moment result can be seen in saved AYL-playlist file only)

15 May 2016
- Masked LCL error (page size of playlist's scroll bar is visually shorter in
  Linux version)

v2.9 beta 18:
27 August 2016
- Could stop playing if to seek backward from position near end of current
  track (fixed)

28 August - 18 September 2016
- Lin: Digital Sound engine and System Mixer has been rewritten for using ALSA
  library, so libbass.so is not used by AY emulation engine now and can be
  removed if you are using Ay_Emul only for chip music formats

29 September 2016
- Lin: passing command line parameters to first instance of Ay_Emul now (like
  in Windows version)
- Command line keys must be started with '-' prefix instead of '/' in Linux
  version (in Windows version can be used both variants)

9 October 2016
- "Add'n'play" shell command behaviour was slightly changed: if group of files
  is added, Ay_Emul is starting playing only first of them instead of trying to
  start playing of all of them (i.e. was playing last of them)

15 October 2016
- Application registration was corrected due last Microsoft recommendations for
  file types association: corresponding information is changed only after
  pressing Register or Unregister button of Tools window, previous default
  handler for file extension is not backuped and not restored (just copied to
  "Open With..." list)
- Due this change your selection of file types in Tools window can not have
  desired effect after series of Register/Unregister pressing (if user was not
  selecting other application manually, all that file types is coming back
  after pressing Register even if you do not select it again before)
- Second new feature after registering: you can type Ay_Emul in command line or
  in Explorer's Run/Search without path to launch AY Emulator

18 October 2016
- Added shell handler to recreate tray icon after Windows Explorer reloading
  due it's crashing

30 October 2016
- Added converting from user defined codepage to UTF8 during parsing headers in
  TRD, SCL and Hobeta formats (to avoid non-ASCII symbols be converted to '?')

31 October 2016
- Skins can be loaded from command line without prefixed key '/p' or '-p' now
- Skins can be loaded by pressing Open button of main window or Add button of
  playlist window (even if they was mixed with usual music files): added
  "Skins" file type mask to the corresponding dialog
- Bug: if Loop button on main window switched to unpushed state during playing
  Internet radio, "Play Next" message is sent (fixed)
- Can lock till end of playing current MIDI-file in some cases like fast Next
  button pressing (fixed)

1 November 2016
- File analizer (finder) can be aborted now for all added files (not only
  current; additional info and button added to corresponding progress dialog)
- Due this change finder is switched on back during dropping folders and files
  on main or playlist window

5 November 2016
- Exocet's small icon is fixed  (removed unused layer and truncated size to
  16x16)

6 November 2016
- Location of default Ay_Emul.ayl playlist was in undefined state if some files
  was pointed in command line (or via shell DDE), so it was saved to config
  folder instead of expected place (fixed)
- Lin: old (MSDOS) filenames in up case was hidden under corresponding Open
  File Dialog filters, so added additional "up-cased" file masks to view them

7 November 2016
- D2L: fixed error in converter to ZXAY (fixed writing to buffer dword values)
- Fixed error in converter to ZXAY (wrong source file checking for AYM, error
  in progress bar for AY and AYM)
- If converting EPSG to PSG with same name, file type is changed, but is not
  redrawn on playlist (fixed)
- Lin: added supported file type registration via mime-types. No set as default
  player for selected types for the moment. Pressing "Register" in Tools window
  saves info about mime-types, icons and application desktop commands (in the
  current user home settings folder). "Unregister" for remove it back. Under
  root user you can check "For all users" to save it in "/usr" directory.
  Anyway you can manually find, edit or copy the files from your home folder

v2.9 beta 19:
20 November 2016
- File analyzer (finder) can detect TS-modules during adding files now (usefull
  if opening disk or tape image with TS-music inside), previously TS module was
  added as two usual standalone modules
- Lin: into Open Dialog added additional "up-cased" file masks for extra types
  like TRD, SCL, etc

21 November 2016
- If file name in disk image has a standard extension (like file.pt3), "Open in
  editor" task has added one more extension (like file.pt3.pt3), fixed

23 November 2016
- On tray mouse click could wrong detect what to do in Windows version:
  minimizing or bring to front if main window is overlapped by "stay-on-top"
  window, fixed

29 November 2016
- Time font is smaller now for big duration music (1 hour and bigger, like
  internet radio)
- Bug of previous beta: after editing playlist item its type is changed (fixed)

v2.9 beta 20:
6 December 2016
- BASS formats loading and playing logic is slightly changed: previously Ay_Emul
  did not using built-in BASS plugin support (load and call corresponding dll
  directly), now all BASS' dlls are loaded as plugins, so BASS can self analize
  which one to use
- Added Opus, AAC, ALAC and DSD BASS plug-ins. Note: if you have corresponding
  codec in system, BASS can play format without additional plug-in (for example,
  AAC, WMA can be preinstalled in some Windows versions or codec-packs)

20 December 2016
- Inline assembler is replaced by pure Object Pascal, including Z80 emulation
- Some errors has been fixed in Z80 emulation during analizing ASM routines
- Free Pascal compiler produces not so good code like Delphi, so it was hard
  decision to remove inline assembler from project, but its need at least for
  future 64-bit version of Ay_Emul

21 December 2016
- 64-bit version for Windows has been made

23 December 2016
- Bug of beta 18: if loading AYL-playlist with PSG music previously saved from
  Ay_Emul, it's type is changed to EPSG (fixed)
- Saving AYL logic is slightly changed: for multiformat file name extensions
  (like .AY or .PSG) parameter "Type=" is written always

27 December 2016
- 64-bit version for Linux has been made

v2.9 beta 21:
7 August 2017
- There are too much cutted ASC and ASC v0 modules in Goblin's Crack Intro
  Archive, so I've decided to add .AS0 file extension (as in that archive),
  and turn off autodetection for files with .ASC and .AS0 extensions (anyway
  it was turned on several betas ago due error)

13 August 2017
- File analyzer (finder) can detect TS-modules since beta 19, but incorrectly
  set next search position if TS is not found (fixed)

16 August 2017
- File analyzer (during adding files to playlist) extracts ASC and STP tags
  from player code block in source file of any type now (previously it extracts
  it only from TRD/SCL/Hobeta and only if player was at begin of corresponding
  catalog item)

17 August 2017
- Files with extension .STP must be not initialized (Ay_Emul "uninitializes" it
  before saving with extension .STP). But seems Goblin uses totally bad ripper
  (for ASC and STP as minimum) and there are too much initialized STP modules
  in Goblin's Crack Intro Archive, so I've decided to add ability of loading of
  such modules. Anyway, in Goblin's archive title from player code of STP is
  inserted incorrectly.
- Total: corrupted modules from Goblin's Cractro Archive (ASC, AS0 and STP with
  titles) are played in Ay_Emul now, but you need rerip it to get right ones
  (just run SCL in ZX Spectrum emulator, save SNA, load it in Ay_Emul and save
  all found modules)
- File analyzer in Tools window is improved: if found tag in player of ASC0, ASC
  and STP module, finder saves two variants of module - without tag (as usually)
  and with tag (added "-tag" to file name to mark it)

v2.9 beta 22:
1 September 2017
- One more "surprise" in Goblin's Cractro Archive - one truncated Super Sonic
  STC module, to rerip it Ay_Emul STC-ripper is slightly modified (it can
  detect Super Sonic modules now, previously I was ripping it manually)
- Added '(C) KLAV "S_SONIC"' to standard STC titles list to skip during loading
  tags (like 'SONG BY ST COMPILE', etc)

4 September 2017
- Firestater reported about very old bug: in some cases (for example, after
  drug'n'dropping to playlist window) new playlist's items are not redrawn
  till window resizing or scrollbar clicking. Fixed.

7 September 2017
- In some cases main window is unaccessable to move by mouse, so own code in
  AdjustFormOnDesktop function is replaced with standard LCL's MakeFullyVisible
- In some collections TS-modules come with .TS file extension, so it was adding
  to Ay_Emul too
- In playlist window for TS-modules filetype is shown now as "PT3x2",
  "PT3+SQT", etc

8 September 2017
- For PT 3.7 TS-modules marker "PT3TS" is shown in playlist window now
  (FormatSpec=0 in AYL)

v2.9 beta 23:
2 October 2017
- FormatSpec=-1 in AYL (default value) is always saved for non-TS PT3 since beta
  22. Fixed.
- Added info about one more ASC player into file analyzer's tag extractor
- File analyzer can extract now tag "SOUND TRACKER COMPILATION OF " from ST 3.xx
  player block during adding files to playlist or during searching for tunes in
  file
- "SOUND TRACKER COMPILATION OF " can be inserted to STC during saving from
  playlist or by tunes finder (same idea like in STP and ASC: some pointers are
  incremented to get place for string inside of song data block). Modified STC
  module is playable by standard players. Modification prevents of losting new
  string during reripping, copying, etc, therefore better than just appending
  to the end of file
- Some tricks are implemented to merge song titles in STC if needed (if STC
  contains two different tags in traditional place and in "SOUND TRACKER
  COMPILATION OF ")

7 October 2017
- Added uncompiled Sound Tracker 1 modules player (shadow compilation to STC is
  performed)
- Added ST1 file extension as id of uncompiled Sound Tracker 1 modules
- "Save As..." for ST1 saves STC (can use as compiler)

v2.9 beta 24:
26 October 2017
- Using current sample rate instead of initial one for BASS spectre
  visualisation

27 October 2017
- Added info about one more ASC player into file analyzer's tag extractor

2 of December 2017
- Added SNDH (Atari ST and Atari STe universal native music format) support.
  SNDH contains original player code for MC68000 processor and music data. Some
  Atari ST/STe hardware is emulated: MFP timers, DMA-Sound, some TOS traps, etc.
  More information about SNDH playing engine can be found in documentation of
  my Micro ST project (http://bulba.untergrund.net/ayplayer_e.htm). SNDH support
  is realised speccially for key-jee (sorry for huge delay, Atari ST emulation
  was a very hard task for me)

3 of December 2017
- Added options for DMA-Sound level and MC68000 frequency in the Mixer window

4 of December 2017
- Added warning labels if mixing can overflow (in Mixer window)
- Added Mixer Amplifier Helper to set all emulated sound devices output levels
  to maximum without overflow (look button in Mixer window)

5 of December 2017
- Added ST/STe, Force YM Mono and Force Mono switches to adjust Atari emulation
  (SNDH player)
- Back to own code in AdjustFormOnDesktop (Firestarter had reported about error
  with several monitors since using standard MakeFullyVisible, so, just
  modified own code)
- Added font selection for Playlist window (specially for Firestarter)
- Fixed error in settings loader (could set random data if setting was not found
  in CFG file)

6 of December 2017
- No information about point of dropping files in Lazarus' OnDropFiles (like
  WinAPI's DragQueryPoint) and Ay_Emul uses alternative way to retrive it.
  Firestarter had reported that Ay_Emul is often mistaking and dropping files
  at random position of playlist. So, drop point detection is switched off,
  dropping files are always added to the end of playlist now
- If author or title string is empty in first module of TS-pair, using second
  module to display info now

v2.9 beta 25:
20 January 2018
- If SNDH-file has contain several tunes, Ay_Emul used Specific playlist
  property to store tune number value, but it was not saved in AYL-file (fixed)

5 February 2018
- Interface is ready to translate to any language, just copy Ay_Emul.po to
  Ay_Emul.*.po in languages subfolder (* is your language id like pl, zh_CN,
  etc) and translate it. You can send me your translations to be included in
  next release of Ay_Emul
- Ay_Emul.ru.po is made for Russian interface, Ay_Emul.po for English (you can
  override it with your own Ay_Emul.en.po)
- lclstrconsts.*.po was copied from Lazarus' LCL sources (to translate LCL
  messages like 'file not found', etc), but they are using only if 
  corresponding Ay_Emul.*.po are present
- Command line l switch is used to point language now, f.e. for English type
  Ay_Emul -len

7 February 2018
- StSound's YM-files are added via detection (header analizing) since several
  versions ago, fixed to load directly
- You can point tune number in command line for SNDH-files now (like for XMI,
  MIDI, AY and AYM): "Ay_Emul file.sndh:0" to play 1st tune,
  "Ay_Emul file.sndh:1" for second one, etc

11 February 2018
- ST1 structure checker is improved to fix broken files like in AAA's archive
  ishodnik.zip\SONG2.SCL\LYRA6.S (you can load and save it in Sound Tracker to
  "fix" it or replace via hex-editor in position list pattern number 9 to 1 to
  really fix it)
- Detector of "Opening/adding file" can detect non-compiled Sound Tracker
  modules now, so you can load or drop TRD/SCL/TAP and ST1 will be extracted
  (could save as STC from playlist, if you need)

12 February 2018
- Modules finder is improoved to search ST1 modules. The tool has saved both ST1
  and STC (uncompiled and compiled) if ST1 is found, so you can use it as ST1
  ripper or as ST compiler

v2.9 beta 26:
22 February 2018
- PSG- and EPSG-files are added via detection (header analizing) since several
  versions ago, fixed to load directly, and also fixed error of beta 25 only
  (PSG and EPSG was not loaded at all with error message)

23 February 2018
- Added several rules to ST1 detector to decrease number of false detections

v2.9 beta 27:
26 October 2019
- Fixed Z80's OUTI, OUTD, OTIR, OTDR emulation (bug due error in
  z80-documented.pdf): B decremented before outing now (thanks to goodboy for
  HeroQuestCPC.ay)
- Added 3-bit mask for CPC's PIO ports F4xx/F6xx & %0000101100000000 (Amstrad
  CPC emulation)
- Rewrote CPC AY output logic for right work with non-standard players (like
  HeroQuestCPC.ay, thanks to goodboy for it)

16 of April 2021
- Fixed manual mixer selection (worked as autodetect)

v2.9 beta 28:
22 February 2022
- Added ZX Sound Tracker Pro uncompiled format support (file extension STF). Can
  be found in various music collection on TR-DOS disk images (with extension .F
  and start address 25000). Just copy from image and change extension to STF.
  Used same method as with Sound Tracker uncompiled: shadow compilation to STP.
- You can use Save as... for STF to compile and save it as STP. If you have
  uncompiled Sound Tracker Pro music collection, you can listen to directly or
  save as STP to get better result than original compilers (built-in in ZX Sound
  Tracker Pro editor): I'd fixed several errors and peformed some optimization
  to get smaller size.

23 February 2022
- Ay_Emul detector was improved to detect ZX Sound Tracker Pro uncompiled modules
  now. You can open or drug'n'drop TRD or SCL image to extract STF, for example.
- Search for tunes in files (Tools window) can be used to search STF (result is
  saved in both uncompiled STF and compiled STP variants.
- Removed MS Sans Serif font from main window (using default for Lazarus' LCL
  now) to fix some national characters viewing.

v2.9 beta 29:
2 March 2022
- Bug fix: player frequency for SNDH without corresponding TAG was set to some
  previously played song value. Added default player frequency 50 Hz to SNDH
  loader now (all SNDHs without player frequency TAG must played as TC50 due
  SNDH v2.1 specification published at sndh.atari.org).

4 March 2022
- Bug fix: Atari ST code page table's character ',' was coded as '0'.

5 March 2022
- SNDH TAGs analyzer was totally rewrote to comply specification requirements
  (sndhv21.txt): removed the most tricks to load bad or damaged SNDH-headers, so
  use good SNDH-files sources now (sndh.atari.org, for example) or rebuild bad
  ones.

6 March 2022
- AY-files of ST11-subtype are supported for now (can be found in AY-music
  archives for Patrik Rak's DeliAY from Amiga). ST11 is the Sound Tracker 1.1
  uncompiled module (aka ST1 in Ay_Emul).

7 March 2022
- Bug fix: some dynamic content labels re-"translated" with default values after
  switching current language (even to same option).
- Removed some strings no need to translate from language files (like AY-3-8910,
  1773400, etc).
- Bug fix of beta 28: all forms translated again each time when open file dialog
  is called.

v2.9 beta 30:
10 March 2022
- Bug fix: STF compiler error due wrong info in KSA's stprhelp.txt about unused
  digits 3-7 in orn/env position. Really them used in editor and in native
  compiler to set ornament 0 (see YIR.F aka BACA&IMP:YOLKA IN RAVE, they set 3
  everywhere).

v2.9 beta 31:
13 May 2022
- ST3 (Sound Tracker 3) compiled modules has been supported. This is special
  format for compiling usual ST1 (non compiled Sound Tracker 1.xx). Ay_Emul
  converts ST3 to STC shadowly before playing, so you can right-click in
  playlist and save selected ST3 as STC without losting any format nuances.
- Patterns and samples numeration starts from 0 in ST3 (in original Sound
  Tracker 1.xx - from 1), so generated corresponding STC is unusual for various
  decompilers (except Vortex Tracker II, of course), but are played correctly
  by any STC-players.

14 May 2022
- "KSA SOFTWARE COMPILATION OF " tag from ST3 is inserted to STC if it's saved
  from playlist. So STC can contain either "SOUND TRACKER COMPILATION OF " or
  "KSA SOFTWARE COMPILATION OF " tag now.
- And again: not all decompilers can evolute or correctly ignore the tag
  (Vortex Tracker II ignore it for the moment), but taged STC are played
  correctly by any STC-players (full compatibility).

15 May 2022
- ST3 modules can be detected during opening files like TRD or SNA. Player body
  tag is extracted and uninitializing (loading address substructing from
  samples and ornaments pointers) is performed too.
- Module finder (in Tools window) is improved to search ST3 modules. For each
  found module both ST3 (with and without tags) and STC (with and without tags)
  are saved, so you can use it to convert ST3 back to STC to play with native
  STC-player.

v2.9 beta 32:
15 June 2022
- AS0 finder improved to detect ASM 0.xx with inserted tag.

22 June 2022
- Native ZX Spectrum FTC-player does not write R13 (envelope type) if same
  value was where already, so Ay_Emul's FTC-player fixed to be identical to
  native one.
- Fast Tracker 1.07 new feature has been supported: for modules with version
  1.07 and higher can be two new note tables pointed in header - Classic (Sound
  Tracker) and 1.75MHz (FTC unique). For previuos FTC 1.00-1.06 old note table
  is used (from Pro Tracker 1-3 aka modified Sound Tracker note table).
- Fast Tracker 1.08 new feature has been supported: full envelope+tone retrig
  special command (listen RE-TRIGG.ftc from FT 1.08 beta 1 package). Seems,
  command is simplified in native FTC 1.08 beta 1 player: if retrig set in
  several channels, used only one from last channel, and Ay_Emul's FTC-player
  do same as native one.

v2.9:
29 June 2022
- Bug fix: Ay_Emul could deadlock during closing in some Linuxes (seen in Rosa
  Linux R12.2 in Oracle's virtual machine) because of no events produced on
  close and free mixer control and mixer thread's poll wait for it infinitely
  (added small timeout to fix).

23 November 2022
- ST11 in AY-files without '.ay' file name extension was not detected (fixed).
- Fixed PT1 detector in "Search for tunes in files" (error in module size
  calculation due not all ornaments store 64 bytes in file). Error just masked,
  found module can be larger up to 63 bytes for now (todo: exact PT1 size
  calculator).
- If calling help (F1 or from About window) tries to launch Ay_Emul.langid.chm
  first where langid is identifier for interface language selected in Tools
  window. If not, launches Ay_Emul.chm (in English).

24 November 2022
- Specially for Mark Kende: added loader for SNDH music duration database by
  Benjamin Gerard if timedb.inc.h or sndhtimedb exist in Ay_Emul folder. Can
  be useful if you have SNDH-files without tunes duration info in header (if
  they exist in the base, of course).

28 November 2022
- Included sndhtimedb from 11/25/2022 to distributive. If you have newer, just
  place original timedb.inc.h to the Ay_Emul folder, and sndhtimedb will be
  generated/regenerated at next startup. The original base can be found in sc68
  project sources:
  https://sourceforge.net/p/sc68/code/HEAD/tree/file68/src/timedb.inc.h

4 December 2022
- Select CD dialog was appeared between monitors if two monitors in the system
  (fixed).

6 December 2022
- Fixed error in PSM pattern decoder for F9 "GoSub" switch (not implemented in
  compiler, therefore it did not lead to a failure).

10 December 2022
- Bug fix: Ay_Emul shown error message on pressing pause on some Linuxes (if its
  sound device not supports pause function, seen in Rosa Linux R12.2 in Oracle's
  virtual machine). Used drop/prepare instead of pause/unpause for such devices.

11 December 2022
- Lin: Added 100 ms pause after closing digital sound device if it does not
  support pause function (to mask some problems in Rosa Linux R12.2 in Oracle's
  VM).

v3.0 beta:
7 February 2023
- ST3 files description updated in Help system (added info about S.T. Music's
  Recompiler).

13 February 2023
- ST3 related strings are changed to indicate S.T. Music's Recompiler as
  origin.

28 September 2023
- Added "Detect FLS" option to the "Open files from folder" dialog (disabled by
  default).

10 November 2023
- Added 'Save all to folder...' item to the Tools button's menu to save all
  found ZX modules without manual providing file name for each one.

18 September 2024
- Fixed Z80's RRD and RLD emulation (used by volume table generator in Spirius
  demo from Enlight'97, see Spirius demo.ay and Spirius demo (without RRD).ay.

30 October 2024
- Specially for AAA added 'Convert all to WAV...' item to the Tools button's
  menu to convert all ZX music to WAV files without manual providing file name
  for each one.
- Included sndhtimedb from 08/08/2024 to distributive (see information above
  how to update it by yourself if you need).

5 November 2024
- Bug fixed: if "Recurse subfolders" option was checked, the global search
  interrupt flag reset each time when the next folder proceded, so searching
  tunes in files during adding from folder continues even if user clicked "Swith
  off tunes finder", i.e. searching process aborted only for the current folder
  and started again with the next folder in queue.

7 November 2024
- Added "ZX81 Compiler A.Re" string to the list of standard ID's for Sound
  Tracker compiled format (as part of "ZX81 Compiler A.Rea." introduced by Andy
  Rea).

8 November 2024
- If selected the group of playlist items and user canceled file dialog for
  current file (or some error occured), all saving process is aborted now.
- The same behaviour was implemented to all converters too.
- New style file naming for saving or converting from playlist: any kind of
  overwrite avoiding hexadecimal suffixes was replaced by Windows-style ones
  (ordinal numbers in brackets).
- Bug fixed: playlist popup menu disables some items for single selected item
  only; if it called over multiselection, all menu items are enabled now (if
  operation is not allowed for some items, just skip it).
- To the help system added additional notes about Fast Tracker's retrig
  command.
- In OUT-file description fixed note about Z80's OUTD and OUTI commands using in
  various native players. It was previously described as error of G.A.Lunter's
  Z80 emulator, in fact error was in Ay_Emul Z80 emulation (fixed on 26 of
  October 2019, see above). Sorry for my bad.
- Due to the switching of the untegrund.net hosting to read-only mode, the site
  has been moved to http://ay.strangled.net/ address. The site is still
  available at the same address (http://bulba.untergrund.net/), but is no longer
  being updated.

12 November 2024
- Updated BASS libraries to the latest versions, BASS_APE replaced by BASSAPE.
- If *.ts does not contain Turbo Sound music, tries to pass it to BASS library
  (can be Transport Stream container, supported by BASS).
- Updated text descriptions for BASS error codes.
- Fixed error: when BASS file playback finished, sometimes playback can jump to
  the file after next one in playlist (double PlayNext message produced).
- Bug fixed: if BASS tryes start module playback after stream file divided to
  subsongs via CUE, an error message can appear.

13 November 2024
- Conversion from popup menu over selected item(s) behaviour is slightly
  changed: you don't need to provide file name for each item if selected more
  than one, just point folder name once (requested by Voxel/Triumph, Max
  Arnold, Vladimir Doulepov and many others). VTX and YM6 file header editor
  dialogs are not appear too (all tags filled from playlist item fields).
- To the Tools button of playlist added menu items to convert entire playlist
  to VTX, YM6, PSG and ZXAY. If conversion is impossible (for example, same
  formats), item is skipped silently.

14 November 2024
- Same behaviour is implemented for saving selected playlist items: ask for the
  file name if selected one module, or ask once for the folder name if selected
  more ones.
- Added converters to MP3, OGG, FLAC and OPUS via BASSenc library, work in the
  same way as conversion to WAV.

18 November 2024
- Added a tags and encoder parameters editor before starting conversion to MP3,
  OGG, FLAC or OPUS. If several selected playlist items or the entire playlist
  are being converted at once, the corresponding dialog appears once.
- Improvement: the main window visualization is now partially enabled during
  conversion (autoscroll of the converted module "Author - Name" line).
- PSG player improved: added  "End of music" marker support (introduced in
  RDOSPLAY, realized in zxtune123). Thanks to Vladimir Doulepov for the test
  file ROBOCOP2.YM.psg (converted by zxtune123).

19 November 2024
- New option in Tools window: "Loop shorter of TS pair". You can force looping
  shorter module of TurboSound pair even if Loop button of main window is
  switched off. To hear difference check Splinter\voices.pt3 after 1:32 with and
  without looping.
- Added the ability to convert TurboSound modules into two PSG files like
  Module.1.psg and Module.2.psg (as in Vortex Tracker II). Since in the PT3.7 TS
  format, both halves can influence each other through the SetTempo command (for
  example, see the first line in Tr_Songs\Authors\John\WeBberTS.pt3), they have
  to be decoded and written to both PSG files synchronously (as when playing).
  In this regard, it was necessary to modify the PSG converter to write two PSGs
  at the same time. This gave rise to a new feature for ordinary TS pairs: if
  the TS pair modules have different lengths (for example, Tr_Songs\Authors\
  Splinter\voicets.pt3), you can save either PSGs with different duration, or
  with the same time length depending off "Loop shorter of TS pair" option of
  Tools window. Thanks to Voxel/Triumph for TS-to-PSG request, but I've decided
  do not modify PSG-format itself.
- Fixed bug: if 1st module of TS pair has smaller duration, time seeking set
  wrong playback position (see Splinter\voices.pt3).
- If Time edited via "List's item adjusting" dialog, the total time was not
  recaclulating. Fixed.
- D2L: Removed message based duration retriving system because LCL's cross
  platform analog of PostMessage work as SendMessage and block other processes
  (visualisation, user input, etc) till all visible playlist items will got
  duration info. Now using timer events for it, so user can do something between
  time calculation requests for each item.
- At the TAD request, returned a prescan of MP3/MP2/MP1 with variable bitrate
  and chained OGG for accurate seek points and duration calculation. Since this
  can greatly slow down the opening a file from a slow medium (for example, from
  a local network), the option can be disabled in the Tools window.
- A new Playlist tab in the Tools dialog, some of the settings from the general
  tab have been moved to.
- Added reseting AY chip registers with zero values before looping PSG, EPSG,
  OUT and ZXAY files to make sound totally same after looping. Although ideally,
  you need to worry about the initial state of all AY registers when recording
  these files, and not when playing them back. Thanks to TAD for test
  GGdefault_1.psg.

21 November 2024
- Improvement: BASS format type is extracted via BASS_ChannelGetInfo (can differ
  from filename extension, or not MP3 if Internet stream).

25 November 2024
- Fixed bug: Playlist window stopped closing by Alt+F4 some versions ago.
- Added reaction to the system scale greater then 100% (High DPI) for all
  Ay_Emul windows and dialogs excepting main window. To do good scaling all
  forms are redesigned.

29 November 2024
- Tested in Linux Mint 64 since Ron reported the issue after upgrading OS: songs
  in the playlist stop instead of playing the next song. Seems, bug is gone
  (whatever where was: in the Ay_Emul or Mint itself).
- PSG converter slightly modified: zero values of registers in 1st interrupt are
  saved now (previously they was dropping out).

1 December 2024
- More long time operations can be canceled now (opening file/folder, total
  duration calculation, etc).
- The long operation canceling functionality was extended to Linux version: you
  can abort both single and group conversion, file(s) saving/opening, total time
  calculation, etc, by click on main window or by pressing Esc.
- Popup hint about the canceling ability is added to the main window during some
  long time operations.
- Added rescan duration of OUT, ZXAY and EPSG files if Z80 frequency was changed
  in Mixer window.
- Added duration info update when checking/unchecking "Get from list" option for
  interrupt frequency in the Mixer dialog.

2 December 2024
- Times are changing: if at the century beginning there were users who found the
  Ay_Emul main window too large, then in the Ultra HD monitors era, the same
  window can be completely covered with a thumb. Especially for Kaens Bard, the
  'Main window double sized' option has been added to the Tools window, which
  solves this problem.

5 December 2024
- Fixed bug: Open and Save file dialog titles was not translated.

7 December 2024
- Some Linuxes display tray icon only if popup menu was assigned. So, added it
  with various useful commands like play / pause / stop, play random track,
  minimize / restore, etc.
- Since Linux apps of Lazarus do not show Application title, where "Author -
  Title" is shown in Windows versions, and also not all Linuxes show tray icon
  hint, show them in main form caption for Linux versions now.

8 December 2024
- Fixed bug: if minimized in Linux Mint, only main form was shown after
  restoring (just check all forms status after restoring, so don't know where
  the bug actually: in LCL or Linux Mint itself).
- Improvement: if the system mixer volume control is not very precise (too few
  steps), then a small movement of the volume control on the main window might
  not change the system volume, causing the slider to immediately move back,
  preventing the ability to adjust the volume from the keyboard or mouse wheel.
