  • Fixed a non-fatal, but longstanding problem that caused locking errors

  • Potential fix for XMMS stopping randomly when using non-queuecontrol enabled plugin

2.0.1 (Dec 09 2004)

• • Make better use of correlation information

  • Give bonus to new songs in collection to facilitate introduction

  • Greatly improve the performance of plugins without queue control

  • Fixed configure misdetecting presense of queue control functions

  • which caused compile errors with XMMS <= 1.2.10

  • Fixed a number of bugs

2.0 (Oct 27 2004)

• • As of this version IMMS no longer just a plugin for XMMS, but rather a generic adaptive playlist framework

  • The core of IMMS runs as a standalone daemon (started automatically), and player plugins connect to it using a unix domain socket

  • Plugins are provided for XMMS and Beep Media Player, plugins for other players should be relatively easy to add

  • XMMS plugin was renamed from libimms.so to libxmmsimms.so, so you will have manually enable the new plugin when upgrading

  • Extended database schema to keep track of more information, paving way for faster new song introduction, etc

  • immsremote was dropped pending a better implementation. immstool got the new "rate" option to manually adjust ratings on songs

  • Lots of cleanup

1.2 (Aug 17 2004)

• • b:

    • • Fixed a typo in one of the queries

      • Added a missing include

      • Fixed Makefile to install binaries to PREFIX/bin instead of just PREFIX

  • a:

    • • Fixed a possible lockup when updating correlations

  • New build system

  • Database layer rewrite, using SQLite 3.0

  • Use of transactions, pre-compiled queries and indexes speed up db operations significantly

  • Acoustic analyzer is now a separate application, further decoupling IMMS from XMMS

  • IMMS is now back to being a General plugin, like it should be

  • Entire collection can now be batch scanned thus gaining immediate benefit of acoustic analysis

  • Much more accurate and reliable bpm comparisons

  • New useful immstool options, like 'identify'

1.1 (Apr 14 2004)

• • Alternative (much cleaner!) XMMS interface that respects shuffle, queue, etc

  • To use the new plugin interface you need XMMS CVS or 1.2.11 (when it comes out)

  • TagLib is now the prefered tag interfacing library

  • Faster secondary correlations

  • IMMS now keeps an internal mirror of the playlist

  • Fancy on-the-fly playlist limiting using immsremote

  • More internal restructuring and bugfixes

1.0.1 (Feb 25 2004)

• • Fixed the time limit on how long we can spend updating secondary correlations

  • Added an option to have IMMS allow normal shuffle/sequential modes for CD tracks

  • Changed color spectrum ratings to only penalize transitions

  • Added a couple of missing includes that broke compilation on some platforms

1.0 (Jan 25 2004)

• • Use acoustic properties of the songs (such as BPM and frequency spectrum)

  • to automatically guess song similarity

  • IMMS is now a Visualization plug-in (Visualization plugins get access to some additional information, such as frequency statistics. IMMS uses this data to calculate song frequency spectrum and BPM and automatically guess song similarity.)

  • Fix secondary correlations

  • Much faster song selection

  • XMMS Queue support vs. XOSD/song change confusion is now configurable

0.9.8 (Nov 08 2003)

    • • The new one should work much better for short playlists

      • This is the first implementation since 0.9 that I am happy with!

  • Reworked song correlation engine that takes into account secondary correlations

    • • I am somewhat concerned about the performance of this algrorithm.

      • Let me know if you experience significant delays between songs.

  • Added an option that should make IMMS work with CrossFade plugin

    • • You have to enable Sloppy skip detection in the Preferences.

  • The queue feature of XMMS should now be working

  • Support for reading native Vorbis tags with libvorbis

  • Levenshtein string distance algorithm allows more accurate song matching

0.8.1

• • use stop instead of pause to make transitions between songs smoother

  • if we cannot identify a songs title/artist, fallback to using the path otherwise unknown songs will always have an unfairly higher chance to get played
