Folks -

Since it's been a while, I've put an updated trunk image on

     http://ftp.squeak.org/trunk/Squeak3.11-8931-alpha.zip

The summary of latest changes is below.

Cheers,
   - Andreas

(for the full history refer to the "What's new" section in the image)

[------------------------- updated 01/23/10 ---------------------------]

Modularity
----------
The following packages have been made reloadable: ReleaseBuilder, 
ScriptLoader, 311Deprecated, 39Deprecated, Universes, SMLoader, SMBase, 
Installer-Core, VersionNumberTests, VersionNumber, Services-Base, 
PreferenceBrowser, Nebraska, CollectionsTests, GraphicsTests, 
KernelTests, MorphicTests, MultilingualTests, NetworkTests, ToolsTests, 
TraitsTests, XML-Parser, Traits, SystemChangeNotification-Tests, 
FlexibleVocabularies, EToys, Protocols, Tests, SUnitGUI. To unload all 
of these, execute:

	Smalltalk unloadAllKnownPackages.

[------------------------- updated 01/02/10 ---------------------------]

NanoTraits
----------
A new traits implementation has been added. The implementation is 
significantly smaller and simpler than the old version and can be 
unloaded and reloaded without loss of information (i.e., traits 
flattened during unload are restored during traits reloading). To unload 
traits simply execute:
     Trait unloadTraits.
To restore traits load the traits package from the repository at 
source.squeak.org.

TextDiffBuilder
---------------
A new algorithm for producing text diffs has been added. The algorithm 
is smaller, faster, and provides better results compared to the previous 
implementation.

Source / Changes Files
----------------------
Sources and changes files are no longer limited to 32MB max size. 
ExpandedSourceFileArray provides an implementation for source files of 
arbitrary length, based on the CompiledMethodTrailer changes.

CompiledMethodTrailer
---------------------
Handling compiled method trailers for storing source code has been 
generalized. The new representation deals more explicitly with various 
forms of encodings (source pointer, temps-only, etc) and has room for 
future extensions (i.e., retrieval from other sources).

Future Messages
---------------
Support for the future/future: keywords has been added. Future messages 
enable sending messaging at a later point in time. Timed futures allow 
sending messages a specific number of miliseconds into the future, 
futures without arguments are executed at the earliest convenience. For 
example a message like:

MyMorph>>mouseDown: event
     self color: Color red.
     (self future: 1000) color: Color white.

will turn the given morph red and one second later back to white.

[------------------------- updated 12/12/09 ---------------------------]

Image Version
-------------
The new version scheme is now active. The image version number is the 
sum of all package versions. A stub package "Squeak-Version" has been 
added to define the "base" number for the version. This image is 
designated as "Squeak3.11.alpha".

Morphic
-------
New window resizers better in tone with the general UI look. A new 
UserDialogBoxMorph for simple modal inform/confirm dialogs.

Files
-----
StandardFilestream now performs read-buffering, dramatically speading up 
some operations like "Object compileAll" (2x improvement) as well as 
various other operations (scanning change lists etc).

Numbers
-------
Implementations for Float #predecessor, #successor etc. Update to the 
compact class indexes of LargePositiveInteger and LargeNegativeInteger 
for Cog. Additional tests for all of the new features.

Exceptions
----------
OutOfMemory has been added as a standard exception being signaled when 
an allocation fails, replacing the previous signaling of the low space 
semaphore. Improved #ensure: performance avoiding remote context 
manipulation (via #tempAt:put:) in the default case.

SUnit
-----
Faster execution by speeding up some low level operations (like 
allTestSelectors). Fixes for thumbnail creation which would leave open 
morphs around after some tests.

Kernel
------
The default hash for all objects is now a scaled identity has to avoid 
extreme degradations in speed when using large numbers of objects 
without explicit hash implementation in Dictionary and Set.
