The 3.8 release is a release with the main purpose of adding the m17n (Multilingualization) changes. (See this thread from squeak-dev for background on this.)
Done
added m17n changes
synch with Squeakland
SystemBrowser Registry: Allows to easily replace the Browser by another (e.g. RB, OmniBrowser)
faster BMP writing (factor 30)
small app for making proxy setting easier (plus automatic proxy setting for MacOS)
An improved harvesting/update stream process will be implemented during 3.8, probably involving two update streams, the ability for a core group of committers to post updates directly, and possibly investigation of an external bug tracking utility. (Some of these are now finished, such as the setup of the Mantis Server bugtracker.)
We'll need to coordinate final release of 3.8 with the people working on the 64-bit Squeak 4.0 project. The original intent was to have the 4.0 release be the same as 3.8, except that 4.0 would include 64-bit support.
