# [v2.7.5](https://github.com/adhearsion/punchblock/compare/v2.7.4...v2.7.5) - [2015-08-27](https://rubygems.org/gems/punchblock/versions/2.7.5)
  * Bugfix: Alternative fix for "Avoid race conditions in processing calls with interactions between them". The original fix in 2.7.4 introduced crashes relating to creating call actors at high call volume.

# [v2.7.4](https://github.com/adhearsion/punchblock/compare/v2.7.3...v2.7.4) - [2015-08-19](https://rubygems.org/gems/punchblock/versions/2.7.4)
  * YANKED
  * Bugfix: Avoid race conditions in processing calls with interactions between them

# [v2.7.3](https://github.com/adhearsion/punchblock/compare/v2.7.2...v2.7.3) - [2015-08-18](https://rubygems.org/gems/punchblock/versions/2.7.3)
  * Bugfix: Handle correct event for confirming that a component stop was completed on Asterisk 13

# [v2.7.2](https://github.com/adhearsion/punchblock/compare/v2.7.1...v2.7.2) - [2015-08-10](https://rubygems.org/gems/punchblock/versions/2.7.2)
  * Bugfix: Process joined events on Asterisk 13 in any order, avoiding Join command timeouts

# [v2.7.1](https://github.com/adhearsion/punchblock/compare/v2.7.0...v2.7.1) - [2015-07-14](https://rubygems.org/gems/punchblock/versions/2.7.1)
  * Bugfix: Ensure components are deregistered from asterisk translator once the call is ended ([#250](https://github.com/adhearsion/punchblock/pull/250))

# [v2.7.0](https://github.com/adhearsion/punchblock/compare/v2.6.0...v2.7.0) - [2015-06-09](https://rubygems.org/gems/punchblock/versions/2.7.0)
  * Feature: Support for Asterisk 13 (AMI v2)
  * Feature: Pass all possible MRCP recognition headers through Asterisk [#244](https://github.com/adhearsion/punchblock/pull/244)
  * Bugfix: Handle an illegal AMI response by Asterisk as a failure with code -1
  * Bugfix: Ensure a useful error is raised when attempting to join to a call which doesn't exist [#529](https://github.com/adhearsion/adhearsion/issues/529)
  * Bugfix: Support SSML in MRCPRecog case on Asterisk. This is the case where a prompt component wants to render using Asterisk and recognise using UniMRCP. This worked fine with a uri-list which already has test coverage, but threw (and silently swallowed) an exception for an SSML doc (as provided by Adhearsion) resulting in a hung call with no audio, and then a timeout exception in Adhearsion. [#241](https://github.com/adhearsion/punchblock/pull/241)

# [v2.6.0](https://github.com/adhearsion/punchblock/compare/v2.5.3...v2.6.0) - [2015-02-01](https://rubygems.org/gems/punchblock/versions/2.6.0)

# [v0.7.2](https://github.com/adhearsion/punchblock/compare/v0.7.1...v0.7.2) - [2011-12-28](https://rubygems.org/gems/punchblock/versions/0.7.2)
  * Feature: Allow sending commands to mixers easily

  * Feature: Return an error when trying to execute an Output on Asterisk with unsupported options set

# [v0.7.1](https://github.com/adhearsion/punchblock/compare/v0.7.0...v0.7.1) - [2011-11-24](https://rubygems.org/gems/punchblock/versions/0.7.1)
  * [FEATURE] Add `Connection#not_ready!`, to instruct the server not to send any more offers.
  * [BUGFIX] Translate all exceptions raised by the XMPP connection into a ProtocolError
  * [UPDATE] Blather dependency to >= 0.5.9

# [v0.7.0](https://github.com/adhearsion/punchblock/compare/v0.6.2...v0.7.0) - [2011-11-22](https://rubygems.org/gems/punchblock/versions/0.7.0)
  * Bugfix: Some spec mistakes
  * Feature: Allow execution of actions against global components on Asterisk
  * API change: The console has been removed
  * API change: Components no longer expose a FutureResource at #complete_event, and instead wrap its API in the same way as #response and #response=. Any consumer code which does some_component.complete_event.resource or some_component.complete_event.resource= should now use some_component.complete_event and some_component.complete_event=
  * Feature: Added the max-silence attribute to the Input component
  * Bugfix: Bump the Celluloid dependency to avoid spec failures on JRuby and monkey-patching for mockability
  * API change: Event handlers registered on components are no longer triggered by incoming events internally to Punchblock. These events must be consumed via a Client's event handlers or event queue and manually triggered on a component using ComponentNode#trigger_event_handler

# [v0.6.2](https://github.com/adhearsion/punchblock/compare/v0.6.1...v0.6.2)
  # Feature: Added basic support for running Punchblock apps on Asterisk. Calls coming in to AsyncAGI result in the client receiving an Offer, hangup events are sent, and accept/answer/hangup commands work.
  # API change: The logger is now set using Punchblock.logger= rather than as a hash key to Connection.new

# [v0.6.1](https://github.com/adhearsion/punchblock/compare/v0.6.0...v0.6.1)
  * Feature: Allow instructing the connection we are ready. An XMPP connection will send initial presence with a status of 'chat' to the rayo domain
  * Bugfix: When running on Asterisk, two FullyBooted events will now trigger a connected event
  * Bugfix: No longer ignore offers from the specified rayo domain on XMPP connections
  * Feature: Tag all event objects with the XMPP domain they came from

# [v0.6.0](https://github.com/adhearsion/punchblock/compare/v0.5.1...v0.6.0)
  * API change: Punchblock consumers now need to instantiate both a Connection and a Client (see the punchblock-console gem for an example)
  * Feature: Added a Connection for Asterisk, utilising RubyAMI to open an AMI connection to Asterisk, and allowing AMI actions to be executed. AMI events are handled by the client event handler.
  * Deprecation: The punchblock-console and the associated DSL are now deprecated and the punchblock-console gem should be used instead

# [v0.5.1](https://github.com/adhearsion/punchblock/compare/v0.5.0...v0.5.1)
  API change: Connections now raise a Punchblock::Connection::Connected instance as an event, rather than the class itself

# [v0.5.0](https://github.com/adhearsion/punchblock/compare/v0.4.3...v0.5.0)
  * Refactoring/API change: Client and connection level concerns are now separated, and one must create a Connection to be passed to a Client on creation. Client now has the choice between an event queue and guarded event handlers.

# [v0.4.3](https://github.com/adhearsion/punchblock/compare/v0.4.2...v0.4.3)
  * Feature: Support for meta-data on recordings (size & duration)
  * Feature: Allow specifying all of Blather's setup options (required to use PB as an XMPP component)
  * Bugfix: Rayo events are discarded if they don't come from the specified domain
  * Bugfix: Component execution in the sample DSL now doesn't expect events on the main queue

# [v0.4.2](https://github.com/adhearsion/punchblock/compare/v0.4.1...v0.4.2)
  * Bugfix: Conference complete event was not being handled

# [v0.4.1](https://github.com/adhearsion/punchblock/compare/v0.4.0...v0.4.1)
  * Feature/API change: Components no longer have an event queue, but instead it is possible to define guarded event handlers via #register_event_handler

# v0.4.0
  * First public release
