The Squeak Wiki collects useful information about the language, its tools, and several projects. It’s a wiki, so you can participate!
The Squeak Development Process supports the improvement of Squeak—the core of the system and its supporting libraries—by its community. The process builds on few basic ideas: the use of Monticello as the primary source code management system, free access for the developers to the main repositories, and an incremental update process for both developers and users.

Downloads come as
*.dmg archives. On macOS, you must drag the included
*.app file out of your
~/Downloads folder to avoid translocation;
mv will not work. On Windows, you must confirm a SmartScreen warning since executables are not yet code-signed.

You can always take a look at the progress in the latest alpha version. Feel free to participate with commits to the inbox. Alpha versions are not expected to be stable. Make sure to also get the latest VM.
Everything is an object. Objects collaborate by exchanging messages to achieve the desired application behavior. The Smalltalk programming language has a concise syntax and simple execution semantics. The Smalltalk system is implemented in itself: Compiler, debugger, programming tools, and so on are all Smalltalk code the user can read and modify. Novice programmers can get started easily and experts can engineer elegant solutions at large.
All graphical objects are tangible and interactively changeable. This promotes short feedback loops and low-effort application development. Morphic thus leverages the live programming experience of traditional Smalltalk environments from a mainly text-focused domain to a graphical one.
The dynamic Squeak environment provides a variety of tools for browsing, writing, executing, and versioning Smalltalk code. Multiple debugging sessions can be served concurrently. Thanks to Morphic, tool customization can be achieved with reasonable effort.
There are several fast Squeak VMs that also support other languages of the Smalltalk family. Meta-tracing, just-in-time compilation, stack-to-register mapping, and aggressive in-line message caching yield efficiency in executing Smalltalk byte code.
A media-rich authoring environment with a simple, powerful scripted object model for many kinds of objects created by end-users that runs on many platforms.
