0.17.3 (2016-01-18) ----- * [#701](https://github.com/celluloid/celluloid/pull/701) Conditions in loose threads loop does not take into account the difference between backtraces from ruby 2.0.0 and greater than. Fixes celluloid/celluloid-io#165. ([@TiagoCardoso1983]) * [#700](https://github.com/celluloid/celluloid/pull/700) Set celluloid logger level to info by default unless debug is enabled. Fixes #667. ([@ioquatix]) * [#695](https://github.com/celluloid/celluloid/pull/695) Extending the condition event handler with the block; this solves a bug introduced in jruby >9.0.0.0, which breaks with an ArgumentError exception, apparently due to the way to_proc procs are passed arguments. Fixes #694. ([@TiagoCardoso1983]) * [#689](https://github.com/celluloid/celluloid/pull/689) Simplified sync, async and future proxies by providing specific AbstractCall base. ([@ioquatix]) * [#688](https://github.com/celluloid/celluloid/pull/688) Fix failure to remove dead actors from sets, e.g. celluloid-supervision.
