Tagged versions and Changelog

There are different tagged versions on the Janus repository. We usually tag a new version any time a breaking change and/or a set of comprehensive changes and fixes is going to be merged/applied to Janus, and so the Changelog below can act as a simple and quick summary of which changes are available in each version.

It's very important to point out, though, that tagged version are NOT to be considered stable versions. This is a common misunderstanding. The only version we consider stable is master as it's the only branch where we continuously provide fixes and enhancements: this is particularly important in the WebRTC world, where it's not uncommon to see features breaking overnight due to changes in how browsers and other WebRTC devices implement things. As such, again, a tagged version is only a way to take a snapshot of where Janus was at a specific point in time, and before a more or less major change occurred. While you're free to stick to tagged versions for your deployments (e.g., because that's how provisioning is usually done in your company), please notice we will ignore issues and reports addressing any other branch that is not master: due to lack of time and resources, we simply cannot go and investigate issues we may have fixed already, so if you're experiencing issues, make sure you can replicate them on master as well first.

## [v0.2.6] - 2017-12-19

- New SIP plugin based on libre, SIPre (janus.plugin.sipre), and related demo
- New NoSIP plugin, that can be used with legacy applications (like SIP) without doing any signalling itself
- VideoRoom can now support multiple codecs at the same time, instead of being forced to choose just one per media type
- Plugins now record streams specifying the actual codec in use, instead of making assumptions (e.g., like Record&Play did with Opus and VP8)
- Streaming plugin now allows you to temporarily pause audio and/or video delivery via "configure" requests
- Removed RTCP BYE as a trigger to shutdown a PeerConnection (fixes Firefox 52 issues)
- Added RTCP support for simulcast SSRCs
- Fixed parsing of Firefox simulcast offer when order of attributes was different than expected
- Improved RTP headers rewriting in case of SSRC changes (e.g., context switches)
- Improved performance of the ICE send threads/loops and computation of transfer rates, by getting rid of all list traversals
- Added support for MSG_EOR in SCTP datachannels
- Added "exchange" support to RabbitMQ transport
- Added new info to Event Handlers (server info in "started" event, and server name in "emitter")
- Added RabbitMQ Event Handler
- You can now add additional constraints for a PeerConnection when invoking createOffer and createAnswer in janus.js
- Fixed occasional problems when postprocessing .mjr recordings, especially long ones, and Opus recordings
- Several bug and typo fixes, in both core and janus.js


## [v0.2.5] - 2017-10-23

- VP8 simulcasting supported in a few plugins (you may have experimented with it on the online demos already);
- VP9 SVC is also available (VideoRoom only);
- VideoRoom and Streaming plugins allow you to subscribe to a subset of the feed's media (e.g., only get audio even though feed is audio/video);
- automatic fallback in the VideoRoom to subset of the media in case of unsupported codecs (e.g., Safari joining VP8 room falls back to audio only);
- added option to override rtpmap and fmtp SDP attributes for RTSP mountpoints in the Streaming plugin;
- added support for other codecs besides opus and VP8 in Record&Play plugin;
- added option to have a static RTP forwarder for an AudioBridge room in the configuration file;
- added possibility to specify an RTP range to use in the SIP plugin;
- implemented text2pcap support to dump incoming and outgoing unencrypted RTP/RTCP traffic for debugging purposes;
- added support to G.722 in postprocessor;
- made sure that each m-line now has its own a=end-of-candidates attribute;
- fixed crash in websockets transport plugin when SSL was enabled on both APIs;
- added support to ping/pong mechanism in websockets transport plugin;
- switched from addstream to addtrack in janus.js;
- decoupled the dependencies in janus.js to allow for dynamic override of some features;
- added support to build JavaScript modules out of janus.js.


## [v0.2.4] - 2017-07-28

- binding to some or all interfaces/families has been fixed in the HTTP transport;
- the Access-Control-Allow-Origin return value is now configurable in the HTTP transport;
- fixed occasional slow WebSocket request management when DNS was involved;
- there's a new timer before we return an ICE failed (as due to trickling there may be a success shortly after a temporary failure);
- the frequency of media stats notifications (event 32) in event handlers has been made configurable (default is still 1s);
- event handlers now notify about each local and remote candidate as well;
- the admin.html demo page now prompts you with the password (although you can still hardcode it in the page, as before);
- several changes in the SIP plugin: support for offerless INVITEs, early media (183+SDP), outbound proxies, and fixes to some POLLERR messages;
- added support for LibreSSL as an alternative to OpenSSL and BoringSSL;
- added a=end-of-candidates to all m-lines, since we half-trickle (fixes Edge support);
- fixed a race condition in the TextRoom plugin;
- fixed the way janus.js used getStats, in particular for Firefox;
- fixed device selection demo;
- several smaller fixes derived from a static analysis of the code via Coverity.


## [v0.2.3] - 2017-06-12

- A few janus.js fixes (among which a small fix to get it working with Safari, and the possibility to add mic audio when screensharing);
- Several RTCP related enhancements in the Streaming plugin;
- Support for on-hold in SIP plugin;
- Fixed MQTT transport when credentials are needed;
- Improved "kick" in VideoRoom (needs forcing of private_id when creating room);
- Possibility to create Streaming mountpoints with random ports, instead of specifying them via API;
- Optional "talking" events in AudioBridge and VideoRoom;
- Possibility to force BUNDLE/rtcp-mux per handle via API (no need to wait for complete negotiation);
- Several bug fixes, a couple of them to nasty race conditions that finally got solved.


## [v0.2.2] - 2017-03-08

- ACL/Kick support in VideoRoom/AudioBridge/TextRoom
- Man pages for Janus and post-processor
- Opaque identifiers for Event handlers + Transport related events
- Ability to specify SSRC + payload type when using RTP forwarders
- Ability to relay datachannels in Streaming plugin
- Ability to send some TextRoom commands (e.g., create/list/etc.) via Janus API instead of only datachannels
- Configurable session timeouts
- Configurable "no-media" timeouts
- Optional temporary extension for recordings until they're done
- cleanup and bug fixing
