[RELEASED] Squeak 4.1
Locked
 
|
On behalf of the Squeak community, I'm happy to announce the
availability of Squeak 4.1. Squeak 4.1 combines the license change occurring in the 4.0 release with the development work that has been going on while the relicensing process took place. Much of the work in this release has been focused on fundamental improvements. Major achievements are the integration of Cog's closure implementation, the improved UI look and feel, the new anti-aliased fonts, the core library improvements, and the modularity advances. To download the Squeak 4.1 release please visit: http://ftp.squeak.org/4.1 The Website will be updated over the next few days to reflect the availability of Squeak 4.1. Enjoy! - Andreas (on behalf of the Squeak community) Overview of Changes 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, which allowed us to decouple the Morphic and MVC implementations for improved modularity. Morphic now has 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 (press the blue button; 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 now an instance of SmalltalkImage, representing a facade for system-wide queries and actions. SmalltalkImage contains a global environment, an instance of SystemDictionary, which the environment used by classes. Thus, SmalltalkImage current == Smalltalk, Object environment == Smalltalk globals. 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. |

Congratulations to everyone!
It took us a long two+ years for bringing a new release, not mentioning a relicensing, which took us even more. So, i am happy, that we were able to get done with that, and many new horizonts are now open. -- Best regards, Igor Stasenko AKA sig. |

Hurrah!
Thank you Andreas, and the many whose work is in this release. Thanks for dropping the .1. This important release deserved a clear non-bugfix release number as its starting point. It's the most compelling Squeak release since I joined the community in ~2001. I'm looking forward to using it and seeing what it leads to. Best, -Simon |

Thanks to all core developers and the others who contributed.
Squeak Boards too deserve a special thank for vision and drive!
Thanks again. Enrico

Congratulations Andreas. It's one thing to make an "app", or even a
"framework", but it's another to make a "Smalltalk". Way to go..

Yes, it is a major step forward.
4.1 has a nice GUI which invites me to do write RCP like apps. The menu bar is great and the system windows look neat. With the ToolBuilder we can create good UIs though there is a learning curve. There are still errors but we can fix them quickly with the trunk approach. It was just yesterday that I realised that there is an entry in Monticello to post to the inbox.

Squeakers: Thank you.
4.1 is a Smalltalk system that I'm not afraid to show to my friends. In particular, the UI improvements that went in will really help me to raise awareness about Squeak in my local community (Seattle, where there is entirely too much C# going around.) I'm glad that Squeak maintains a visual identity (even if we did yoink it mostly from Newspeak, heh) rather than emulating a mainstream look and feel.
I wanted to point out: 4.1 has a much larger delta than what will be absolutely necessary to justify future releases; it could probably have been code frozen and shipped a lot sooner if we hadn't been waiting on a license-clean 4.0 artifact. 4.2 is, in my mind, much closer than 4.1 was to (temporally speaking) 4.0.
It's been a good year. Ever since the commits started rolling in, I've met some really great people, was honored to run with the relicense ball, (even if I botched the release email, lol!) and I've learned a lot about Smalltalk.

I'm hardly an expert in using it, but what few bugfixes I contributed, I found it easy to use. Heck, actually, it took me all of an hour to go from never having looked at the Browser to being able to commit a fix. I chalk that up entirely to ToolBuilder's ease of use. frank |

Hi,
