### Fixed
* Fix issue where calling Worker.find, Worker.all, or Worker.working from withing
  a running job would rewrite the PID file with the PID of the forked worker.

* Run eager load hooks for Rails applications versioned 4.x and up (@abhi-patel)

### Added

## 1.25.0 (2013-4-16)
* Updates fork method so [resque-multi-job-forks](https://github.com/stulentsev/resque-multi-job-forks)
  monkey patching works again. See discussion at https://github.com/defunkt/resque/pull/895 for more
  context (@jonhyman)
* Use Redis.pipelined to group batches of redis commands.
  https://github.com/resque/resque/pull/902 (@jonhyman)
* Fixed uninitialize constant for the module/class that contains the perform
  method causing job failures to no be reported, #792 (@sideshowcoder)
* Fix Resque::Failure::Base.all to have the correct signature.
  (@rentalutions)
* Don't close stdio pipes when daemonizing so as to not hide errors. #967
  (@sideshowcoder)

  parent when the forked child exits. #1017 (@magec)

* Fix CI for 1.8.7 and 1.9.2 modes due to dependencies. #1090

  listening on `staging_*`. #1085 (@adelcambre)


## 1.24.1 (2013-3-23)

* Adds a default value for `per_page` on resque-server for plugins which add tabs (@jonhyman)

* Added missing `require 'time'` which was causing occasional errors which
  would crash workers.

## 1.24.0 (2013-3-21)

* Web UI: Fix regression that caused the failure tab to break when using
  certain failure backends (@kjg)
* Web UI: Add page list to queues (@ql)
* Web UI: Fix regression that caused the failure tab to break when clicking on
  "clear all failures" under certain failure backends, #859 (@jonhyman)
* Fix regression for Resque hooks where Resque would error out if you assigned
  multiple hooks using an array, #859 (@jonhyman)
* Adds ENV["RUN_AT_EXIT_HOOKS"] which when set to 1 causes any defined
  `at_exit` hooks to be run on the child when the forked process exits, #862

* Remove multi_json, the JSON gem does the right thing everywhere now.
* Documentation fixes with demo instructions.

  a signal handler, which can potentially cause deadlock. Now we're using
  `mono_logger`, which has no locks.
