The changes below are for v2.8.5 which was replaced by v2.8.6 for Linux (source). There is only one one difference to 2.8.5 - VST-enabled builds for Linux are possible. There are no functional changes, and absolutely no changes for Mac OS X, hence the current version for Mac OS X is v2.8.5.

General changes:

• MMC (and other remote control protocols) no longer causes Ardour to discard recorded material when stopping transport.
• Fix latency compensation when punching in (which was a regression in 2.8.2)
• Fix crash when loading a session with certain kinds of crossfades
• Fix "crashes" caused by an endless loop of events related to the editor track "big text cursor"
• Don't cause clicks and/or possible plugin problems when editing while the transport is stopped
• Load plugin presets at the right time
• An implementation of "Save As" (result is still saved within the session folder)
• New option in editor track list context menu to show only tracks that have regions under the playhead
• Initialize the export folder name correctly
• Initialize system template folder name correctly
• Fixes for 64 bit build with some versions of gcc (ensures that assembler optimizations will be used)
• Plugin "favorites" file format modified for portability. We are sorry that you will lose your list of favorites (and/or hidden plugins) after upgrading.
• Updated translations for Italian, Russian, Swedish, Norwegian

Mac OS X only:

• Fix potential (and observed) crash in AudioUnit plugins caused by Ardour's incorrect setup of data buffers
• Fix crash when using AudioUnit plugins that use tempo/meter information from Ardour
• Fix discovery of AudioUnit factory presets
• Reimplement integration with the OS X main menubar
• Make all shortcuts work (Ardour used to ignore many or most Alt/Option- combinations)
• Fix issues with the cache of AudioUnit configuration data, and ensure that the file can be safely updated in the future.
• Fix display of AudioUnit GUI's written in Carbon (no more "white windows of death")
• Make international language support work on OS X (Ardour will try, and generally succeed) to follow the preferences you specify in System Preferences).
