Old News:

2001-09-08 Version 3.8.0pre2
* ID3Lib maintainer has disappeared.  Project maintenance taken over by existing
  developers
* Many bug fixes -- mostly compilation problems -- more detailed info will be
  provided in a later release.

2000-11-20 Version 3.8.0pre1

* First prerelease of 3.8.0 stable.
* Clean separation of interface and implementation to help ensure interface and
  binary compatibility of future releases
* Completely revamped implementation of tag reading and writing
* Better debugging output in debug mode
* New documentation (much more still needed)
* Command-line options processing now more cross-platform
* Removed all exception handling
* Minor changes to public interface
* Use of std::string and other STL classes in implementation
* id3com source code removed from source distribution.  It has moved to its own
  project at http://sourceforge.net/projects/id3com
* Many more changes than can be mentioned here:  see ChangeLog file

2000-09-07 Version 3.7.13

* id3com is broken; maintainer has disappeared; anyone care to fix it?
* Complete reimplementation of ID3_Field: cleaner, safer, faster, clearer, more
  efficient
* Much more robust MusicMatch parsing
* Improved conversion from ID3v2 to ID3v1
* Cleaner implementation of file processing
* Examples now use popt for command-line processing
* Improved portability for Macintosh
* Improved build process for platforms without popt or zlib
* New documentation about the MusicMatch tagging format
* Minor updates to ID3_Field interface
* New interface behavior: 
    // copies entire string (same for unicode_t*)
    size_t ID3_Field::Get(const uchar*, size_t) 
    // for lists, copies a specific item in string (0-based)
    size_t ID3_Field::Get(const uchar*, size_t, index_t);
    // returns the size in characters for strings, in bytes for all else
    size_t ID3_Field::Size() cosnt;
    // returns the rendered size of the field
    size_t ID3_Field::BinSize() cosnt;

2000-07-07 Version 3.7.12

* Removed debugging output left over from 3.7.11
* Update() now updates all tag types by default, not just ID3v2
* Added a second, optional parameter to ID3_GetComment to find a comment with
  a specific description
* Converting an ID3v1 comment to an ID3v2 COMM frame now has the description
  "ID3v1 Comment"
* An ID3v2 COMM frame will only be converted to an ID3v1 comment if it has a
  description of "ID3v1 Comment"

2000-07-05 Version 3.7.11

* Now parses and converts files with MusicMatch tags (beta - needs testing!)
* New tag type enums: ID3TT_LYRICS3, ID3TT_LYRICS3V2, ID3TT_MUSICMATCH, 
  ID3TT_PREPENDED, ID3TT_APPENDED.  Deprecated ID3TT_LYRICS
* Improved file processing routines; cleaned up interface w.r.t. files
* Stripping one type of appended tag strips them all
* New C function: ID3Tag_HasTagType
* New methods for ID3_Tag: GetPrependedBytes(), GetAppendedBytes(), 
  GetFileSize(), and GetFileName()
* New function for calculating size of non-tag data in file: ID3_GetDataSize()
* Render now parameterized on ID3_TagType
* Bug fixes

2000-06-23 Version 3.7.10

* New and updated example tags
* Corrected unicode parsing and rendering
* Improved parsing/conversion of Lyrics3 v2.00 tags
* Fixed errors with exception handling (thanks to Luca Leonardo Scorcia for the
  bug reports)
* Fixed bugs/memory leaks with removing frames and updating tag (thanks to Luca
  Leonardo Scorcia for the bug reports)
* Fixed finding of frames with empty text fields (thanks to Luca Leonardo 
  Scorcia for the bug reports)
* Improved documentation/implementation for uint28
* Added GetTextID() method for ID3_Frame objects
* Tag doesn't render if there aren't any frames; frame doesn't render if there
  aren't any fields
* Reordered ID3_AddSyncLyrics() parameters for better consistency with other
  helper functions
* ID3_GetSyncLyricsInfo() parameters updated to be more specific
* Several other minor bug fixes

2000-05-28 Version 3.7.9

* Added new test programs in examples/ for creating example tag files
* Further improvements to compile on (Unix) systems that don't have zlib
* Fixed a bug when parsing compressed frames (thanks to Christian Becker for 
  the bug report and example file)
* Fixed several bugs when writing to files (thanks to Lothar Egger and Peter 
  Thorstenson for the bug reports)
* New delphi example code for use with id3com (thanks Michael Little)
* Bugfixes for id3com (thanks John Adcock)
* Changed behavior of Link() and Clear() in ID3_Tag: Clear() doesn't remove
  file reference, and Link'ing to an already-linked tag just changes the file
  reference
* Cleaned up the class interfaces to use size_t, flags_t, and index_t rather
  than luint, so as to be more descriptive
* ID3_Tag::RemoveFrame() now returns the pointer to the frame removed (NULL if
  not present), thus releasing the tag from its repsonsibility of managing that
  frame's memory
* Cleaned up C interface so that appropriate function parameters are const
* Cleaned up implementation of ID3_Tag::Clear() to fix inconsistencies
* Deprecated ID3_Tag's HasV2Tag(), HasV1Tag(), and HasLyrics() methods in 
  favor of ID3_Tag::HasTagType() method
* All Render() methods now const
* Added GetUnsync() method to ID3_Tag
* Cleaned up internal class definitions (thereby destroying binary 
  compatibility)
* ID3v2 tag now won't render (and its reported size is 0) if there aren't any
  frames (per the spec)
* Fixed a bug when copying frames that prevented rendering compressed frames in
  certain situations
* Fixed a bug with resyncing that caused it to improperly handle the last byte
* Fixed a bug with recognizing certain sync signals
* Lots of other minor changes

2000-05-11 Version 3.7.8

* Major bug fix that caused all string frames to be written out as unicode, yet
  with the wrong encoding information given
* Bug fix for stripping id3v2 tags that wouldn't remove enough data
* Bug fix for writing id3v1 tags that might add extraneous data to the tag

2000-05-10 Version 3.7.7

* As part of the major rewrite of underlying codebase started with previous
  release, this release features near-complete reimplementation of most of the 
  ID3v2 parsing code - smaller, faster, and better organized
* Much imporved Lyrics3 v2 tag support, along with much improved synchronized
  lyrics (SYLT) support (thanks Severino Delaurenti)
* Updated id3com to reflect changes to compression strategy introduced in last
  release (thanks John Adcock)
* Cleaned up the parameters to several functions/methods with regards to 
  constness
* Several new methods to several classes
* A variety of bugfixes

2000-05-03 Version 3.7.6

* Beginning of major rewrite of underlying codebase to improve efficiency,
  expandability; the interface will need minor updates through this endeavor
  (sorry!)
* Major bugfix in ID3_Tag::Strip which was deleting too much info from a file
  in certain circumstances
* Add descriptions to frames; can access either through a ID3_Frame method for
  a frame object, or via the static method on the class (w/ ID3_FrameID param)
  (thanks John Adcock for descriptions, Daryl Pawluk for spotting misorder)
* Frame compression is determined frame by frame, so deprecated 
  ID3_Tag::SetCompression() for ID3_Frame::SetCompression().
