• Fixed problem when loading playlist and a song from the unloaded playlist was already playing.
• Deleting entries from a playlist doesn't auto-use use it anymore.
• Sorting by size and time is now much faster.
• Loading entries from the playlist now actually loads the right entry, not just the one with the same exact filename. but this basically makes it faster...
• Added support for WinAmp style .pls playlist files including SHOUTcast. Titles for SHOUTcast servers are loaded from the .pls so you see all the neat stuff like the load of the servers when you load the playlist.
• Fixed problem loading HTTP URLs with no path like on SHOUTcast.
• Included procedure in netscape.html to properly configure pm123 as a Netscape Navigator helper application.
• Fixed memory leak when removing entries from the playlist.
• Streaming buffer now works properly and continues playing buffered stream even if read operations are stalled.
• Broken HTTP connections are now properly canceled and closed on stop.
• Added workaround for timing problem in DART for setting volume right after the device is opened.
• HTTP URL with no filename like SHOUTcast now show the complete host instead of interpreting it as a filename. Title streaming is on its way...

MPG123

• Fixed streaming audio by adding two in a row header checking.
• Implements new pm123 decoder plug-in interface.
• Fixed floating point exception crashes. Let me know if you can still reproduce any SYS3183.
• Fixed problem with MP3 EQ range calculation with low frequency overflowing table and screwing up memory when MPEG 2.5 Layer III files were played.
• Added support for virtual host names in HTTP123.DLL
• In HTTP123.DLL, fixed seeking (and also loading) problems and glitches, especially with slow media (like CD-ROMs) and big read buffers. But be wise, Read Ahead buffering produces an unnecessary overhead on fast media.
• Added mp3->wav decoder. Command line utility only for now.
• For developers, added a play status semaphore. It can be used to sleep instead of DosSleep() with the advantage of knowing exactly when the player stops.
• Fixed MMPM crash when DART underrun occurs.
• Fixed Equalizer mute crash.
• FileInfo (in playlist) was always reporting 0 length songs.
• Fixed possible infinite loop in read ahead header.
• Added support for Xing Variable Bitrate MP3s.
• Added auto-repause kludge so that when MMOS/2 gives access back to the sound device, the bug in MMOS/2 doesn't unpause mpg123.
• Added new 10 bands ISO normal frequency equalizer for MP3s *only*. The interface (which also needs to be fixed) will not be updated until Taneli has more time on his hands, but here are the bands. Also note that the decibel calculation was wrong before (way too loud).
• 12kHz MPEG 2.5 Layer 3 files now play.
• Added fix for new Xing encoded MP3s from mpg123 0.59q
• Added read ahead header check. This should make ALL valid MP3s even with broken headers work, and should not identify anything else than MPEG audio files as MPEG audio files such as bitmaps lying around in your MP3 directories.
• Added fix for Aurora from dink.
• oops, broke some MP3s for nothing, it's back all right now
• play 48 at 44 works right now
• found some Audio MPEG Header documentation. Should now work with any MP3s other players or decoders play, if not, please contact me. I've also fixed 8000Hz MP3 support, cool.
• patched possible divide by zero when loading corrupted files.
• implemented workaround for bad GUS driver DART buffer timing (it jumps by 250 ms step once in a while instead of incrementing for each buffer). Makes decoderPlayingSamples() work correctly on GUS.
• finally found the proper buffers to flush. no more first buffer trash kludge and now any snap crackle and pop are REALLY only coming from your sound card alone (check the visual plug-ins if you don't believe me)
• faster seek by boosting priority (oops, forgot this initially :)
• audio engine now fills empty buffers with 128 value instead of 0 for 8 bit playback (removes the clicks, but it still sounds like shit :).

PM123 1.01

• Fixed bug in WinAmp skin loading that caused PM123 to crash
• Fixed a WinAmp skin seek slider glitch - please reconvert your seek slider problematic skins
• You don't have to add ".lst" when saving a playlist anymore
• Spectrum analyzer plug-in revised:
  - Added falloff
  - Made analyzer area droppable
  - Frequency chop allows you to drop unused frequencies
  - More efficient spectral leakage reduce method
• Added a warning if some bitmaps of a skin were not found
• Added read ahead buffering in streaming audio
• HTTP.DLL renamed to HTTP123.DLL
• Fixed Warp 3 glitches in fonts
• Fixed a crash in playlist sort
• Added a new settings (and a new settings page): - Play 48 kHz as 44 kHz
  - Streaming audio settings
  - Default display mode (filename, ID3 tag, information)
• Fixed font bug in older skins
• Fixed a bug in the Unregistered window which caused it to hover above all windows
• Fixed bug when pressing Alt-F4 in the main window
• Fixed Recall-menu behavior
• Added a new "smooth scroller" with DBCS and national character support, which can be activated by starting PM123 with the "-smooth" switch
• Improved 256-color support
• Shift-click Play/Stop button while playing to fade out and stop playing

MPG123

• fixed timing bug between MP123_PLAY and MP123_STOP
• added buffer mode to HTTP123.DLL and in MPG123.DLL. rewinding and fast forward will give a quirk in buffer mode sometimes.

PM123 1.0

• Improved skin handling (making it possible to make PM123 look almost 1:1 with WinAmp)
• Improved palette handling
• Fixed WarpAMP playlist loading
• Fixed drag'n'drop playlist reorganizing
• Changed GBM.DLL to GBM123.DLL because people might have other non-compatible GBM.DLLs in their LIBPATH.
• Added 82 more genres, including WinAmp genre extensions
• PM123 can now take `advantage' of full window dragging in Warp 4
• Drag'n'dropping a directory presents a menu where you can select recursive or non-recursive adding
• Properties dialogs refined
• Added 'auto play on playlist use'
• Added selectable scrolling setting
• Added 'Edit ID3 tag' to main menu
• Added PM123 Skin Utility with WinAmp skin conversion and skin bundling
• Playlist file adding moved to threads
• Multiple directory drop
• Main window accepts multiple files and/or directories
• PM123 remote control via \PIPE\PM123 (even over the network)
• Added frequency and mode to playlist info field, and to main display (click on the song name)
• Added visual plug-ins
• Added graphical equalizer with band mute and preamplifier
• Improved HTTP handling
• Added M3U support in playlist
• Spectrum analyzer, CPU usage and oscilloscope plug-in
• Real Equalizer

MPG123

• decoderFileInfo can now be called more than once at the same time
• kludged the jump to command to trash the first buffer (until I figure out more on the digital audio processing and where it keeps the buffer)
• enlarged filename length from ~512 to ~1024, allows for bigger URL I guess.
• now compiled with VAC++, works better with DLLs than EMX
• RxDecoderError now works
• decoderError now reports non-critical errors
• decoderError now queues error messages, empty it, or you'll memory leak
• added filter plug-ins
• added possibility to change the decoder's band gain (there are only 32 linear bands, at the moment, this means at a sample rate of 44100, ~689Hz per band = 44100/2/32) they suck BTW
• added decoderPlayingSamples, to catch a few samples real time from the OS/2 DART audio system to display real time stuff like an oscilloscope or a spectrum analyzer. Note, it will get a buffer length in bytes, you have to calculate how many of them you need according to the bitspersample and channels.
• decoderFileInfo now reports 0 on success and some error code otherwise.
• decoderPlaying extension as decoderStatus
• new kludge that plays 48kHz PCM at 44.1kHz. This is really ugly, you don't hear a big difference, but you're better off converting it. If you are wondering why I'm not converting it real time 1. more CPU time needed *OR* 2. sounds real bad (aliasing and company)
• HTTP module now in HTTP.DLL

PM123 pre 1.0 Beta 2

• Added keyboard shortcuts:
  * Left/Right = Rewind/Fast Forward
  * Enter = Play/Stop
  * 5 (on numeric keypad) = Pause
  * Up/Down = Next/Previous song
  * Alt F4 = Quit
  * +/- = Increase/Decrease volume
• Added skin support
• Fixed shuffle
• Fixed RIFF headered and/or broken MP3 support
• Added seek slider (grab seek slider to move within MP3)
• Fixed control button errors
• Enhanced/fixed tag editor
• WarpAMP playlist loading

MPG123

• decoderTime(PLAYEDSECS) now shows the position being played, not decoded.
• when buffers are trashed for rew and ffwd, the mpeg stream file position is brought to the file position that the decoder was at when it filled the currently playing audio buffer.
• the decoderTime(TOTALSECS) now reports something until all audio buffers are played.
• max buffers locked to 200 and min to 5. these are 16KB buffers, and they seem like absolute limits anyway.
• fix crash when there was an MCI error when starting playing and pm123 already played something before (trying to free memory it didn't allocate)
• the first buffer is trashed to prevent the playing of the last buffer of the previous stream (I can't figure out what's going on, help me!!!) Whatever snaps, crackles and pops left are due to your MPEG streams or your sound card.
• new decoderFileInfo(). allows program that need to check validity or specs of an mpeg stream with mpg123
• stop now unpauses the stream before closing.
• opening http streams should work better now.
• much better rewind and fast forward (makes jumptosecs work a lot better too)
• reporting errors should be more reliable
• http routines now report usable error messages
• http routines now check for "Content-Length" to determine total time
• seeking and timer routines now use the file position instead of keeping track of the frame numbers. makes the decoder faster and more consistent with the total time.
• added REXX support ... hum

PM123 pre 1.0 Beta 1

• First public release
