Here is a list of features that we should avoid to reinvent/reimplement.
If you want to help there is space.

> [------------------------- 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.

**** already in the bugtracker => 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.
> 

**** we should have a look  => 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.
> 

**** already in Pharo => 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".

In general we should have a look at ToolBuilder improvements
> Morphic
> -------
> New window resizers better in tone with the general UI look. A new 
> UserDialogBoxMorph for simple modal inform/confirm dialogs.
> 


**** we should have a look  => 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).
> 

**** we should have a look  => 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.
> 
> **** already in Pharo  => Exceptions
> ----------
> OutOfMemory has been added as a standard exception being signaled when an 
> allocation fails, replacing the previous signaling of the low space semaphore.


**** we should have a look  => 
> 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.
> 


**** Martin is working on that I imagine   => 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.
> 
> [------------------------- updated 11/28/09 ---------------------------]
> 
> Menu Bar
> --------
> Squeak now has a standard menu bar to make it easier to discover its contents 
> for new users, replacing the World menu as the prime source for launching 
> tools and other activities.


> **** from pharo =>  Compiler
> --------
> Support for literal ByteArray syntax has been added. Byte arrays can now be 
> written as #[1 2 3 "..."] instead of #(1 2 3) asByteArray  avoiding the need 
> for conversion and a more compact default representation.
> 

> *** in pharo => Numbers
> -------
> Some prime related changed: Integer>>isPrime is now a deterministic test, 
> Integer>>isProbablyPrime a probabilistic variant. Intger>>highBit and 
> Integer>>lowBit have been sped up significantly.
> 

*** in pharo => CRLF Handling
> 
> -------------
> CR and LF are now treated interchangeably in rendering. Both cause a line 
> break and both are not displayed. Various line related methods have been 
> updated to deal with both CR and LF.
> 


> Collections
> -----------
> Dictionary is no longer a subclass of Set. HashedCollection is the new 
> superclass for both Set and Dictionary.

***Normally in pharo but not sure
> Conversion of OrderedCollection and SortedCollection to Arrays has been sped 
> up significantly.
