<commit_before>### Next Release v0.8.1 (TBD)

* Pure Java implementations of
  - `AtomicBoolean`
  - `AtomicFixnum`
  - `Semaphore`
* Fixed bug when pruning Ruby thread pools
* Fixed bug in time calculations within `ScheduledTask`
* Default `count` in `CountDownLatch` to 1
* Use monotonic clock for timeouts on all platforms where supported

## Current Release v0.8.0 (25 January 2015)

* 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

### Release v0.7.2 (24 January 2015)

* New `Semaphore` class based on [java.util.concurrent.Semaphore](http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/Semaphore.html)<commit_msg>Updated CHANGELOG<commit_after>### Next Release v0.9.0 (Target Date: 5 April 2015)

* Pure Java implementations of
  - `AtomicBoolean`
  - `AtomicFixnum`
  - `Semaphore`
* Fixed bug when pruning Ruby thread pools
* Fixed bug in time calculations within `ScheduledTask`
* Default `count` in `CountDownLatch` to 1
* Use monotonic clock for all timers via `Concurrent.monotonic_time`
  - Use `Process.clock_gettime(Process::CLOCK_MONOTONIC)` when available
  - Fallback to `java.lang.System.nanoTime()` on unsupported JRuby versions
  - Pure Ruby implementation for everything else
  - Effects `Concurrent.timer`, `Concurrent.timeout`, `TimerSet`, `TimerTask`, and `ScheduledTask`
* Deprecated all clock-time based timer scheduling
  - Only support scheduling by delay
  - Effects `Concurrent.timer`, `TimerSet`, and `ScheduledTask`
