## [2.2.0] - 2018-08-16
### Added
- EditList support in ISO-BMFF in both input and output (#112).
- Multi-DRM support with --protection_systems flag (#245).
- HLS AVERAGE-BANDWIDTH support (#361).
- Dynamic Ad Insertion preconditioning support with Google Ad Manager (#362, #382, #384).
- Configurable UDP receiver buffer size (#411). This can help mitigate or
eliminate packet loss due to receiver buffer overrun.
- Allow non-zero text start time (#416). Needed for live text packaging.
### Changed
- Deprecated --mp4_use_decoding_timestamp_in_timeline.
- Deprecated --num_subsegments_per_sidx.
- Generate DASH IF IOP compliant MPD with mpd_generator by default.
- Adjust timestamps in ISO-BMFF if there is an initial composition offset
as we believe that an EditList is missing in this case (Related to #112).
- Add an adjustable offset to transport streams (MPEG2-TS, HLS Packed Audio)
(Related to #112). The offset is configurable with
--transport_stream_offset_ms. The default is 0.1 seconds.
- Set default --segment_duration to 6 seconds.
- Set default --clear_lead to 5 seconds. Shaka Packager does not support partial encrypted segments,
so if segment_duration is 6 seconds, then only the first segment is in clear, with all the
following segments encrypted.
- Set default --io_block_size to 64K.
- Disable Legacy Widevine HLS signaling for HLS with Widevine protection system by default. Use flag
--enable_legacy_widevine_hls_signaling to enable it if needed.
### Fixed
- Build failures in Windows with CJK environment (#419).
- Segmentation fault when processing WebVTT with out of order cues (#425).
- Support WebVTT cues without payload (#433).
- segmentAlignment is not set correctly in static live profile for multi-period
content (#435). Theoretically it could happen for single period content as
well, but with very low possibility of occuring.
- Segmentation fault when packaging with an empty VTT file (#446).
- Possible file name collision when --temp_dir is used (#448).
### Doc
- Added documentation for PlayReady and FairPlay (#306).
- Added examples for TrickPlay.
- Fixed live HLS example (#403).
- Fixed DockerHub instructions link (#408).
- Added documentation for Dynamic Ad Insertion preconditioning.
- Added instructions for missing curl CA bundle on mac.
