• PlainRtpTransport.js: Add missing methods and events.

2.6.9

• Remove a potential crash if a single encoding is given in the Producer rtpParameters and it has a profile value.

2.6.8

• C++: Verify in libuv static callbacks that the associated C++ instance has not been deallocated (thanks @artushin and @mariat-atg for reporting and providing valuable help in #258).

2.6.7

• Fix wrong destruction of Transports in Router.cpp that generates 100% CPU usage in mediasoup-worker processes.

2.6.6

• Fix a port leak when a WebRtcTransport is remotely closed due to a DTLS close alert (thanks @artushin for reporting it in #259).

2.6.5

• RtpPacket: Fix Two-Byte header extensions parsing.

2.6.4

• Upgrade again to OpenSSL 1.1.0j (20 Nov 2018) after adding a workaround for issue #257.

2.6.3

• Downgrade OpenSSL to version 1.1.0h (27 Mar 2018) until issue #257 is fixed.

2.6.2

• fuzzer: fix some wrong memory access in RtpPacket::Dump() and StunMessage::Dump() (just used during development).

2.6.0

• Integrate libFuzzer into mediasoup (documentation in the doc folder). Extensive testing done. Several heap-buffer-overflow and memory leaks fixed.

2.5.6

• Producer.cpp: Remove UpdateRtpParameters(). It was broken since Consumers were not notified about profile removed and so on, so they may crash.
• Producer.cpp: Remove some maps and simplify streams handling by having a single mapSsrcRtpStreamInfo. Just keep mapActiveProfilesbecauseGetActiveProfiles()` method needs it.
• Producer::MayNeedNewStream(): Ignore new media streams with new SSRC if its RID is already in use by other media stream (fixes #235).

2.5.3

• Don't announce muxId nor RTP MID extension support in Consumer RTP parameters.

2.5.2

• Enable RTP MID extension again.

2.5.1

• Disable RTP MID extension until #230 is fixed.

2.5.0

• Add RTP MID extension support.

2.4.6

• Fix a crash in when no more RTP ports were available (see related issue #222).

2.4.1

• Update dependencies.

2.4.0

• Allow non WebRTC peers to create plain RTP transports (no ICE/DTLS/SRTP but just plain RTP and RTCP) for sending and receiving media.

2.3.3

• Fix C++ syntax to avoid an error when building the worker with clang 8.0.0 (OSX 10.11.6).

2.3.2

• Channel.js: Upgrade REQUEST_TIMEOUT to 20 seconds to avoid timeout errors when the Node or worker thread usage is too high (related to this issue).

2.3.1

• H264: Check if there is room for the indicated NAL unit size (thanks @ggarber).
• H264: Code cleanup.

2.3.0

• Add new "spy" feature. A "spy" peer cannot produce media and is invisible for other peers in the room.

2.2.7

• Fix H264 simulcast by properly detecting when the profile switching should be done.
• Fix a crash in Consumer::GetStats() (see related issue #196).

2.2.6

• Add H264 simulcast capability.

2.2.2

• Improve issue #209.

2.2.1

2.2.0

• Update Node and C/C++ dependencies.

2.1.0

• Add localIP option for room.createRtpStreamer() and transport.startMirroring() [PR #199](#199).

2.0.16

• Improve C++ usage (remove "warning: missing initializer for member" [-Wmissing-field-initializers]).
• Update Travis-CI settings.

2.0.15

• Make PlainRtpTransport also send RTCP SR/RR reports (thanks @artushin for reporting).

2.0.14

2.0.10

• Make ICE+DTLS more flexible by allowing sending DTLS handshake when ICE is just connected.

2.0.8

• Disable stats periodic retrieval also on remote closure of Producer and WebRtcTransport.

2.0.7

2.0.4

• Fix #159: Don’t rely on VP8 payload descriptor flags to assure the existence of data.
• Fix #160: Reset targetProfile when the corresponding profile is removed.

2.0.3
