Changelog

0.4.0 (April 21, 2019)

Now SquirrelJME has the SummerCoat virtual machine which is much lighter and faster than SpringCoat. There should definitely be very noticable performance increases.

SquirrelJME is also available on RetroArch since the implementation of RatufaCoat which is written in C and is capable of using the SquirrelJME Runtime.

More detailed changes:

• Build system
  • Launching
    • An alternative VM may be specified.
    • The profiler snapshot can be written to a specific file.
    • System properties may be defined and passed to the launched program.
  • Started work on JavaDoc generation.
• Tests
  • Adjusted the results in the logarithm test to adjust the ulp to what SquirrelJME generates. The results are still valid as it is valid to be within a 1 ulp range, however the test framework only supports exact values.
  • Added the missing mimemessage file for the MIME file decoding test.
• Classes
  • Implemented
    • java.io.InputStream
    • java.util.EventObject
    • java.util.LinkedList
  • Deprecations
    • net.multiphasicapps.classfile.ExecutableCode, not used.
  • Additions
    • java.util.Vector, was missing.
    • Added proprietary ExtendedTaskManager interface which can be used to specify arguments, system properties, and console output alternatives to launched tasks.
• Programs and Libraries
  • demo-hello
    • Made the system properties array final.
  • tac
    • Override standard output and forward to standard error while a test is running, so things are not kludged.
  • tac-runner
    • Allow specific tests to be ran via the main arguments.
    • Generate JUnit output which can be used in test environments.
    • Performed some refactoring on the deserialization/serialization code.
• Compiler Backend
  • MergedPathSet can be initialized by iterables now.
  • Implemented a new tree based unit system for packages and classes.
  • Added a bunch of string representations for class structures.
• Virtual Machines
  • General
    • Adjusted the Shaded JAR directory layout and added a dash in the path so that classes technically become invalid.
    • Allow properties to be obtained from internally passed system properties.
    • Added string representation for the stack map table.
    • Add ability to start tasks with command line arguments, system properties, and alternative console redirection (to capture output).
  • SpringCoat
    • Add support for system properties being based to virtual machine instances.
    • Profiler thread lists are easier to read because the main suite is listed instead of the VM identifier.
  • SummerCoat
    • New Virtual Machine, register based.
    • Vast improvements over SpringCoat, faster and slimmer.
  • RatufaCoat
    • New Virtual Machine, based off SummerCoat.
    • Fast and slim, written in C.
• Cleanup
  • Removed the test.sh script, it was empty.

0.2.0 (December 25, 2018)

SquirrelJME's first release!

Note that this is a work in progress and not everything will run, due to the implementation being incomplete. However it does work and is proven to work, which means progress can continue as such. Later releases of SquirrelJME will always be an improvement over the older versions.
