- ^'SqueakMap is an integrated catalog of external applications for Squeak.  It is accessible from the "Apps" menu.  This catalog does not host the projects, it merely documents the load scripts required to correctly bring them into the image.
-
- Many SqueakMap packages use Installer, which defines several packages in its package-definitions protocol.  Any of these can be loaded with an expression like the following:
-
- Installer new merge: #openGL
-
- Change #openGL to the selector name of the package you want to load.  The latest version of that package and all of its prerequisites will be merged into the image.  Merging a package is no different from loading it unless the package is already loaded, in which case it is upgraded to the latest version in a way that preserves any local changes you may already have made.

- Release Notes

- A New Memory Model and Virtual Machine
-
- Fast Become
- Squeak 5 introduces a new object model and VM known as "Spur".  Presented [1] by Eliot Miranda and Clément Béra at the International Symposium on Memory Management in year 2015, this new VM retains the direct-pointer representation of objects in previous Squeak versions but now without requiring a full scan of the heap for become.  This is done by introducing hidden forwarding objects which allow references to be updated lazily as they are encountered.  Spur''s innovation is in avoiding explicit read barriers in all common cases.
-
- Additional Immediate Types
- The new Spur memory model supports immediate Characters, so that Characters with unicode greater than 255 can be tested via #==, and wide string access is much faster.  The 64-bit version, still under development, also provides immediate floats, occupying the middle 8th of the double precision exponent range.
-
- Simplified and Ready for 64-bit
- Internally Spur uses a 64-bit object header, a representation shared between the 32-bit and 64-bit versions, and one that is significantly simpler than the three different header sizes used in the previous version.  This simplicity means that the JIT now generates code to implement more primitives, in particular new and new:, resulting in significantly higher performance, at the cost of a 15% increase in image size.
-
- Enhanced Memory Management
- Spur has a segmented heap, allowing the heap to grow and shrink a segment at a time.  It provides per-object pinning to ensure specific objects will not be moved by the garbage collector, hence simplifying the FFI.  Spur provides Ephemerons which allow for per-object finalization and the prevention of uncollectable cycles, for example in global property lists like DependentsFields (although this support has yet to be applied to the system).
-
-
- Squeak now runs on ARM
-
- As a natural output of the Scratch application on Rasberry Pi project, the Spur VM can now run on the Rasberry Pi.
-
-
- The Future of Spur
-
- Work is underway on an innovative adaptive optimizer/speculative inliner, and a 64-bit JIT for x64, and a global incremental mark-sweep collector is planned.  See [2].

- ^'The Squeak UI has some unusual elements that you may not have seen before.  Here is a brief introduction to those elements:
-
- Projects
- A project is an entire Squeak desktop full of windows.  Projects can be used to change quickly from one task to another.  An inactive project is represented by a project window, which shows a thumbnail of its state.  Project windows are actually more like doors than windows, since you can enter the project just by clicking on them.  You can create a new project by choosing ''open...project'' from the screen menu.  To exit a project (and return to its parent project), choose ''previous project'' from the screen menu.  Each project maintains its own set of windows and other information.
-
- Morphic Halos
- In a morphic project, pressing cmd-click (Mac) or alt-click (Windows) on a graphical object (e.g. a window) will surround it with a constellation of colored circles.  These are called "halo handles."  Additional clicks will cycle through the halos for the other graphical objects in the nesting structure.  If you hold down the Shift key while cmd/alt-clicking, the nested morphs will be traversed from innermost outward.  Clicking without the cmd/alt key will dismiss the halo.  While the halo is up, letting the cursor linger over one of the halo handles for a few seconds will cause a balloon to pop up with the name of that handle.  Three useful handles are the top-left "X" handle (delete), the bottom-right yellow handle (resize), and the brown handle (slide the object within its containing object).  Halos allow complex graphical objects to be explored - or even disassembled (using the black halo handle).  Usually no harm results from taking apart an object; you can just discard the pieces and create a new one.
-
- Flaps
- To enable Flaps, click on the desktop to show the world menu, choose the "Flaps..." menu and "show shared tags". Tabs labeled "Squeak", "Tools", "Supplies", etc., will appear along the edges of the Squeak desktop.  Click on any tab to open the corresponding flap.  Drag a tab to resize the flap and to relocate the tab.  Bring up the halo on any tab and click on its menu handle to be presented with many options relating to the flap.  Use the "Flaps..." menu, reached via the desktop menu, to control which flaps are visible and for other flap-related options and assistance.
-
- Parts Bins
- You can obtain new objects in many ways.  The "Objects Catalog" (choose "objects'' from the world menu or open the objects flap) and several of the standard flaps (e.g. "Tools" and "Supplies") serve as "Parts Bins" the for new objects.  Drag any icon you see in a Parts Bin and a fresh copy of the kind of object it represents will appear "in your hand"; click to deposit the new object anywhere you wish.  You can also add your own objects to any of the flaps - just drag your object over the tab, wait for the flap to pop open, then drop the object at the desired position in the flap.

- ^'Starting and Quitting
- Like most Smalltalks, the machine-executable portion is a relatively small program known as the "virtual machine" (VM).  The VM''s job is to provide services from the physical machine to real Smalltalk objects.  Services like input and output.  The Smalltalk system, including all data and code, is a system of objects, built from the ground up, and interpreted by this virtual computer.  This affords Smalltalk system platform portability.
-
- Smalltalk cannot run without the VM.  The VM can''t do anything useful except process Smalltalk systems.
-
- To start the system, drag the ".image" data file to the VM executable "squeak".  There are myriad command-line options for starting the system via the command-line (see squeak --help).  By default, the system will open on the screen in a single OS window.
-
- To quit a Squeak session, choose ''quit'' from the menu bar.  If you save, the image file will be overwritten and resume from that place the next time it''s launched.
-
- The Image File
- Squeak is an environment built in its own objects from the ground up, including one or more end-user applications.  All of the objects in the system -- Classes, Dictionaries, Windows, Customers and other objects that make up the Squeak environment are stored in a binary ".image" file.  This is the "object-data file" loaded by the VM when Squeak is launched.
-
- When an image is started, every object resumes exactly from where it was last saved.
-
- The Sources File
- Smalltalk is traditionally includes the source code in the running system.  However, keeping multiple copies of the same source code in all images files is wasteful.  Therefore, the source code itself is kept in a read-only .sources file and accessed by all images.  The image files merely have pointers into this file, which is read on-the-fly to present original source code.
-
- The code of the base system is stored in the file "SqueakV46.sources".  This file does not change except between releases of Squeak.  Normally this file should be placed in the folder containing the VM executable.
-
- The Changes File
- The purpose of Squeak is to develop new programs and systems.  Code changes to the running system are effective immediately.  But since multiple images can be running, they cannot all update the .sources file safely.  Therefore, each image file is accompanied by a ".changes" file which contains source code changes for that and only that Smalltalk system..
-
- The changes file is important for project work.  It keeps a sequential log of development activity for the purpose of recovering work performed since the last image-save.  Any of several events could lead to the need to recover work, including a power-outage or making an erroneous change to code required to keep the system running.
-
- The changes file does not consume memory space, so Squeak is able to keep a complete history of all program changes.  This makes it easy to examine or even reinstate older versions of methods (see ''versions'' option in browser selector pane).  This encourages experimentation, since you can easily revert to the original versions of any set of methods.
-
- In extreme cases where sources and/or changes files are not available, the system can still run, and will automatically decompile the bytecode methods in image memory, if necessary, into readable and editable versions of the original source code (only comments and temporary variable names are lost).
-
- Transferring Code-Snippets Between Images
- In addition to the ''save'' command that saves the entire state of the system, the code of individual methods, categories or classes may be ''filed out'' and then filed-in to another image.
-
- Packages
- The code of an entire project is encapsulated by a Package.  This allows users to share their code with other users.  Code of packages are delineated by the categories of their classes, and methods.  The Monticello browser is then used to wrap that code into a Package object which can be saved to a Monticello repository at http://ss3.gemtalksystems.com/ss.
