# Changelog



# 0.12.3

 * Fix bug in fields naming in callback contexts. [#569](https://github.com/membraneframework/membrane_core/pull/569)

 * Update exit reasons of Membrane Components and their supervisors. [#567](https://github.com/membraneframework/membrane_core/pull/567)



## 0.12.2

 * Fix bug in order of handling actions returned from callbacks.



## 0.12.1

 * Introduce `:remove_link` action in pipelines and bins.

 * Add children groups - a mechanism that allows refering to multiple children with a single identifier. 

 * Add an ability to spawn anonymous children.

 * Remove `:playback` action. Introduce `:setup` action. [#496](https://github.com/membraneframework/membrane_core/pull/496)

 * Add `Membrane.Testing.Pipeline.get_child_pid/2`. [#497](https://github.com/membraneframework/membrane_core/pull/497)

 * Make callback contexts to be maps. [#504](https://github.com/membraneframework/membrane_core/pull/504)

 * All Membrane Elements can be compatible till now on - pads working in `:pull` mode, handling different `demand_units`, can be now linked.

 * Output pads working in `:pull` mode should have their `demand_unit` specified. If case it's not available, it's assumed that the pad handles demands in both `:bytes` and `:buffers` units.

 * Remove _t suffix from types [#509](https://github.com/membraneframework/membrane_core/pull/509)

 * Implement automatic demands in Membrane Sinks and Endpoints. [#512](https://github.com/membraneframework/membrane_core/pull/512)

 * Add `handle_child_pad_removed/4` callback in Bins and Pipelines. [#513](https://github.com/membraneframework/membrane_core/pull/513)

 * Introduce support for crash groups in Bins. [#521](https://github.com/membraneframework/membrane_core/pull/521)

 * Make sure enumerable with all elements being `Membrane.Buffer.t()`, passed as `:output` parameter for `Membrane.Testing.Source` won't get rewrapped in `Membrane.Buffer.t()` struct.

 * Implement `Membrane.Debug.Filter` and `Membrane.Debug.Sink`. [#552](https://github.com/membraneframework/membrane_core/pull/552)

 

## 0.11.0

 * Separate element_name and pad arguments in handle_element_{start, end}_of_stream signature [#219](https://github.com/membraneframework/membrane_core/issues/219)

 * Refine communication between parent and its children [#270](https://github.com/membraneframework/membrane_core/issues/270)

 * Add `handle_call/3` callback in the pipeline, as well as a `:reply` and `:reply_to` actions. Rename `handle_other/3` callback into `handle_info/3` [#334](https://github.com/membraneframework/membrane_core/issues/334)

 * Add `Membrane.FilterAggregator` that allows to run multiple filters sequentially within one process. [#355](https://github.com/membraneframework/membrane_core/pull/355)

 * Log info about element's playback state change as debug, not as debug_verbose. [#430](https://github.com/membraneframework/membrane_core/pull/430)

 * Rename `Membrane.Time.to_<unit name>/1` into `Membrane.Time.round_to_<unit name>/1` to indicate that the result will be rounded. Make `Membrane.Time.<plural unit name>/1` accept `%Ratio{}` as an argument. Add `Membrane.Time.round_to_timebase` function.

 * New `spec` action syntax - the structure of pipeline is now defined with the use of `Membrane.ChildrenSpec`

 * Rename `:caps` to `:stream_format`.

 * Use Elixir patterns as `:accepted_format` in pad definition.

 * Delete `:ok` from tuples returned from callbacks 

 * Remove `:type` from specs passed to `def_options/1` macro in bins and elements.  

 * Add `Membrane.Testing.MockResourceGuard`



## 0.10.0

 * Remove all deprecated stuff [#399](https://github.com/membraneframework/membrane_core/pull/399)

 * Make `Membrane.Pipeline.{prepare, play, stop}` deprecated and add `:playback` action instead

 * Make `Membrane.Pipeline.stop_and_terminate` deprecated and add `Membrane.Pipeline.terminate/2` instead

 * Add `Membrane.RemoteControlled.Pipeline` - a basic implementation of a `Membrane.Pipeline` that can be spawned and controlled by an external process [#366](https://github.com/membraneframework/membrane_core/pull/366)

 * Disallow sending buffers without sending caps first [#341](https://github.com/membraneframework/membrane_core/issues/341)

 * Refine the `Membrane.Testing.Pipeline` API - deprecate the `Membrane.Testing.Pipeline.Options` usage, use keyword list as options in `Membrane.Testing.Pipeline.start/1` and `Membrane.Testing.Pipeline.start_link/1`



## 0.9.0

 * Automatic demands [#313](https://github.com/membraneframework/membrane_core/pull/313)

 * Stop forwarding notifications by default in bins [#358](https://github.com/membraneframework/membrane_core/pull/358)

 * More fine-grained control over emitted metrics [#365](https://github.com/membraneframework/membrane_core/pull/365)



 ### PRs not influencing public API:

 * Added log metadata when reporting init in telemetry [#376](https://github.com/membraneframework/membrane_core/pull/376)

 * Fix generation of pad documentation inside an element [#377](https://github.com/membraneframework/membrane_core/pull/377)

 * Leaving static pads unlinked and transiting to a playback state other than `:stopped` will result

 in runtime error (previously only a warning was printed out). [#389](https://github.com/membraneframework/membrane_core/pull/389)

 * It is possible now to assert on crash group down when using Testing.Pipeline. [#391](https://github.com/membraneframework/membrane_core/pull/391)



## 0.8.2

 * Fixed PadAdded spec [#359](https://github.com/membraneframework/membrane_core/pull/359)

 * Fix unknown node error on distribution changes [#352](https://github.com/membraneframework/membrane_core/pull/352)

 * Add new type of element, `Membrane.Endpoint` [#382](https://github.com/membraneframework/membrane_core/pull/382)



## 0.8.1

 * allow telemetry in version 1.0 only [#347](https://github.com/membraneframework/membrane_core/pull/347)

## 0.8.0

### Release notes:

  * PTS and DTS timestamps were added to `Membrane.Buffer` structure explicitly. Timestamps should no longer live in `Membrane.Buffer.metadata` field [#335](https://github.com/membraneframework/membrane_core/pull/335).



### PRs not influencing public API:

  * add CHANGELOG update verification [#340](https://github.com/membraneframework/membrane_core/pull/340)
