 # Changelog
 
+## [1.1.0] - 2018-11-26
+
+### Removed
+- `adm_parent` references in ADM objects.
+
+### Added
+- `Matrix` type support.
+- Simple validation of ADM data model, and more extensive validation of ADM
+  structures.
+- Support for rendering objects with silent `audioTrackUID` references.
+- Support for `audioPackFormat` HOA parameters.
+- Selection of `audioProgramme` and complementary `audioObjects` from
+  `ear-render`.
+- `adm_path` to `RenderingItems`, with pointers to the corresponding ADM
+  objects. This is not used by the renderer but is a useful feature for other
+  applications built on top of the underlying ADM library.
+- Support for more flexible referencing of nested `audioPackFormats`; each
+  `audioTrackUID` or `chna` row can reference any appropriate `audioPackFormat`
+  on the path from the root `audioPackFormat` (which contains the full set of
+  `audioChannelFormats` used) to the `audioPackFormat` that contains the
+  `audioChannelFormat` of the track.
+- Better support for using multi-channel `audioPackFormats` -- in an
+  `audioObject` or `chna`-only file using multiple `audioPackFormats` may be
+  ambiguous if they share some `audioChannelFormats`. This should now be
+  handled correctly in all cases.
+
+### Changed
+- The reference direction between `audioTrackFormat` and `audioStreamFormat`
+  was reversed in the data model (`audioTrackFormat`s now point at a single
+  `audioStreamFormat`), and `axml` references in either direction now establish
+  this relationship. Note that this does not follow the exact wording in
+  BS.2076-1, but this helps compatibility with other systems and should match
+  future revisions of BS.2076. If either of these references are omitted a
+  warning will be issued when a file is rendered. When generating BW64+ADM
+  files (with `ear-utils`) both reference directions are now included.
+- Complete re-implementation of `RenderingItem` selection to support other
+  features in this release. This functionality was moved from
+  `ear.fileio.utils` to `ear.core.select_items`.
+- `RenderingItems` now use the `TrackSpec` structure rather than an index to
+  point to their source audio, to allow for silent and `Matrix` tracks.
