3.3 (Stable Release)
====================
* __Feature:__ Added human- and machine-readable exit reasons for most processes, which indicate _why_ a process shut down.
* __Feature:__ Added `OUTPUT_END` trigger, which signals exit reason for all pushes (and not just those that push to file)
* __Feature:__ Added `INPUT_ABORT` trigger, which signals exit reason for inputs that close with a non-clean exit reason
* __Feature:__ The built-in Meta-Player now supports reading subtitle and metadata tracks over websocket, regardless of playback protocol
* __Feature:__ Support for JSON metadata tracks in MPEG-TS inputs/outputs
* __Feature:__ Support for ingesting AMF metadata over RTMP/FLV and converting to JSON metadata track
* __Feature:__ Added new "JSONLine" protocol that supports simple line-by-line ingest of subtitles or JSON metadata in real time over standard input or a listening TCP socket
* __Feature:__ Support for creating smaller clips out of any live or VoD stream either on-viewer-demand (all HTTP-based outputs) or on-system-demand (any output compatible with the push output system)
* __Feature:__ Support for MP4 push output ("regular" MP4 for clips and/or VoD, fMP4 for live streams)
* __Feature:__ Chromecast support in the built-in Meta-Player
* __Feature:__ Video pop-out support in the built-in Meta-Player
* __Feature:__ Added configurable input idle timeout (previously hard-coded to 15 seconds)

* __Improvement:__ Updated `RECORDING_END` trigger, which now signals the exit reason for pushes to file
* __Improvement:__ Support for sending API calls as `application/json` Content-Type with pure JSON in the request body
* __Improvement:__ Minimum processing latency for live streams has been reduced from 1 packet (frame) on _each_ track to 1 packet/frame on _any_ track

* __Improvement:__ MP4 output more strictly conforms to spec, improving compatibility with the Apple ecosystem
* __Improvement:__ CPU efficiency improvement in all outputs and especially in MP4-based outputs
* __Improvement:__ HLS input's DVR capability was significantly improved (entire input stream DVR window is now available as Mist's DVR window, at minimum), plus major efficiency improvements to HLS and TS parsing code
* __Improvement:__ MP4 analyser now supports analysing and printing individual frames/packets
* __Improvement:__ SRT output now by default includes all tracks instead of a single track per type
