v0.9.0

Our biggest release to date. Too many changes to list here. Please see the CHANGELOG for more details. The most important changes are:

• Deprecation of many APIs that will not be in the 1.0 release
• Creation of an Edge gem where all new and potentially unstable abstractions can be initially released
• Moving of several abstractions/classes into Edge
• Creation of many new abstractions/classes
• Many, many bug fixes and performance optimizations
• Improved tests
• Improved build process

v0.9.0.pre3

Finalizing API and Yardoc. We plan mostly bug/test fixes between now and the full release of 0.9.0.

v0.9.0.pre2

Finalizing API and Yardoc. We plan mostly bug/test fixes between now and the full release of 0.9.0.

v0.9.0.pre1

Nearing finalization of the API. Some internal restructuring is still necessary. The changelog and readme are out of date and do not accurately reflect all the changes since the last release.

0.8.0

This is the first release to use the new model for C and Java native extensions. Java native extensions are built into the core gem and published as a pre-compiled Java build (in addition to the pure-Ruby core gem). C native extensions for MRI are published as a separate extension gem. The main extension gem must be compiled on installation, but pre-compiled Windows binaries (x32 and x64) are published as well. Specific features in this build include:

• C extension for MRI have been extracted into the concurrent-ruby-ext companion gem.
  Please see the README for more detail.
• Better variable isolation in Promise and Future via an :args option
• Continued to update intermittently failing tests

Extension Gem Pre-release 3

A private release used to fix and test pre-compiled extensions for Windows. It was never pushed to Rubygems.

0.7.2

• New Semaphore class based on java.util.concurrent.Semaphore
• New Promise.all? and Promise.any? class methods
• Renamed :overflow_policy on thread pools to :fallback_policy
• Thread pools still accept the :overflow_policy option but display a warning
• Thread pools now implement fallback_policy behavior when not running (rather than universally rejecting tasks)
• Fixed minor set_deref_options constructor bug in Promise class
• Fixed minor require bug in ThreadLocalVar class
• Fixed race condition bug in TimerSet class
• Fixed race condition bug in TimerSet class
• Fixed signal bug in TimerSet#post method
• Numerous non-functional updates to clear warning when running in debug mode
• Fixed more intermittently failing tests
• Tests now run on new Travis build environment
• Multiple documentation updates

Extension Gem Pre-release 2

This release builds two gems from this repo: concurrent-ruby and concurrent-ruby-ext, the latter of which contains the C-native extensions that were added to the core gem in the 0.7 release.

• Background describing why we're making this change: New Approach to C/Java Native Extensions #186
• The PR from which this pre-release was created: Builds two gems from one repo. #205
• A prior attempt to to create two gems from two separate repos (rejected): Moved C extensions into a companion gem. #197
