# Unreleased [Compare master with v1.0.3](https://github.com/intrepidd/working_hours/compare/v1.0.3...master) # v1.0.4 * Fixed a nasty stack level too deep error on DateTime#+ and DateTime#- (thanks @jlanatta) # v1.0.3 * Relax configuration input formats - [#10](https://github.com/Intrepidd/working_hours/pull/10) * Small improvements to the Readme _08/11/2014_ # v1.0.2 * Dropped use of `prepend` in favor of `alias_method` for core extensions to increase compability with jruby. _15/10/2014_ # v1.0.1 * Fix bug when calling ``1.working.hour.ago`` would return a time in your system zone instead of the configured time zone. This was due to a conversion to Time that loses the timezone information. We'll now return an ``ActiveSupport::TimeWithZone``. _10/10/2014_ # v1.0.0 * Replace config freeze by hash based caching (config is recompiled when changed), this avoids freezing unwanted objects (nil, timezones, integers, etc..) _15/09/2014_ # v0.9.0 * First beta release _24/08/2014_
