>>> Welcome to Squeak - a free, open Smalltalk system.

>>> Squeak 4.1 combines the license change occuring in the 4.0 release
>>> with the development work that has been going on while the relicensing
>>> process took place. Here are the highlights of the changes that
>>> resulted in Squeak 4.1:
>>>
>>> User Interface
>>> --------------
>>> We have adapted the 'face lift' look originally developed for
>>> Newspeak. For those of us who like colored windows (quite a few as it
>>> turns out) you can switch between uniform and colored windows in the
>>> 'Extras' menu under 'Window Colors'.
>>>
>>> The new menu bar makes Squeak much easier to discover than before. The
>>> process of transitioning from the world menu is not complete yet,
>>> there are still items that can only be accessed from the world menu
>>> (i.e., by clicking on the desktop).
>>>
>>> The search field integrated in the menu bar allows for direct
>>> navigation to classes and methods - simply type in a partial class or
>>> method name and see what happens.
>>>
>>> A new set of inexpensive sub-pixel antialiased fonts derived from the
>>> DejaVu fonts ('Bitmap DejaVu' in the font chooser) has been added.
>>> True type font support has been upgraded to operate directly on files
>>> on disk without the need to load the entire file into memory.
>>>
>>> A new set of text editors has been added, allowing to decouple the
>>> Morphic and MVC implementations for improved modularity. Morphic has
>>> now regular blinking insertion point cursors instead of the (virtually
>>> invisible) static cursor previously.
>>>
>>> Compiler
>>> --------
>>> Squeak 4.1 includes the closure implementation from Cog as a
>>> prerequisite for full Cog adoption later. With this implementation
>>> Squeak finally has 'full' closures, allowing classic recursive
>>> examples like the following to work:
>>>
>>> fac := [:n| n > 1 ifTrue:[n * (fac value: n-1)] ifFalse:[1]].
>>> fac value: 5.
>>>
>>> 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.
>>>
>>> Selectors including minus are now parsed correctly, for example 3 <- 4
>>> is now parsed as (3) <- (4) instead of (3) < (-4). White space is no
>>> longer allowed after an unary minus to denote a negative number literal.
>>>
>>> Development
>>> -----------
>>> Syntax highlighting, based on Shout, is now included in all Squeak
>>> tools by default. For workspaces, it can be explicitly disabled in the
>>> window menu (entry 'syntax highlighting').
>>>
>>> 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.
>>>
>>> MessageTrace has been added, allowing senders and implementors to be
>>> viewed without opening new windows all the time. It utilizes a new
>>> AlternatePluggableListMorphOfMany, which allows quick and easy
>>> customization of the list. A quick adoption of DependencyBrowser has
>>> been added allowing to browse dependencies between packages.
>>>
>>> Core Libraries
>>> --------------
>>> Sets can now store nil just as any other collection. The collection
>>> hierachy has been refactored to have both Set and Dictionary a
>>> subclass of HashedCollection instead of having Dictionary a subclass
>>> of Set. Squeak now uses a better distributed scaledIdentityHash for
>>> identity sets and dictionaries.
>>>
>>> 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).
>>>
>>> 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).
>>>
>>> A new extensible number parser hierharchy has been introduced
>>> NumberParser and its subclasses provide support for parsing and
>>> building numbers from strings and streams.
>>>
>>> A new general cleanup protocol has been added. The cleanUp protocol
>>> takes an optional argument to indicate whether we're doing an
>>> aggressive cleanup (which involves deleting projects, change sets, and
>>> possibly other destructive actions) or a more gentle cleanup that's
>>> only supposed to clean out transient caches.
>>>
>>> SystemDictionary and SmalltalkImage have been refactored. Smalltalk is
