This upgrade also introduces exact stack rooting (see to the wiki:
JSRootingGuide) and fixes problems with moving GC. This allows us to
enable generational garbage collection (GGC).
Measurements a few months ago have shown a performance improvement of a
non-visual replay of around 13.5%. This probably varies quite a bit, but
it should be somewhere between 5-20%. Memory usage has also been
improved. Check the forum thread for details.
Thanks to everyone from the team who helped with this directly or
indirectly (review, finding and fixing issues, the required C++11
upgrade, the new autobuilder etc.)! Also thanks to the SpiderMonkey
developers who helped on the #jsapi channel or elsewhere!

This was SVN commit r16214.
Each GUI Page gets its own compartment and all ScriptInterfaces in the
same thread should now use the same JS Runtime.
This is required for the SpiderMonkey upgrade.
Check the ticket for details.

This was SVN commit r14496.
The Multiplayer lobby needs some changes to avoid compartment
mismatches. Instead of initializing it with a ScriptInterface and
storing script values at different locations, it takes a ScriptInterface
argument in the functions that really need to read or write some script
values and avoids storing values as script values with an associated
compartment where possible.
The scripting interface of the lobby is also adjusted to use
JSInterface_Lobby.h/cpp files as other components instead of adding all
functions to ScriptFunctions.cpp. This makes it a bit more clearly
arranged IMO.
