Didier,

Have you removed the goal of doing the R-mode from 2.3.0?
Which bugs from 2.2.0 were not fixed in 2.1.0+patches?

Cheers

Regards,
Yakir

    Hello all,
    
    
    The major version 2.2.0 of the ROHC library was just released.
    
    This release introduces the ROHCv2 IP-only, IP/ESP and IP/UDP profiles.
    
    
    == About the ROHC library ==
    
    The ROHC library provides an easy and robust way for applications to
    reduce their bandwidth usage on network links with limited capacity or
    expensive costs. Headers of network packets are compressed with the
    ROHC protocol and algorithms.
    
    The ROHC protocol is very efficient for compressing VoIP streams that
    use RTP as transport protocol. ROHC is also suitable for compressing
    IP-only (IPv4 or IPv6) flows, UDP flows and many others.
    
    The library is published as Opensource under the license GNU LGPL
    version 2.1 or later.
    
    See https://rohc-lib.org/ and
    https://rohc-lib.org/presentation/rohc-protocol/ for more details.
    
    
    == Release notes & changelogs ==
    
    The 2.2.0 release includes:
    * support for the ROHCv2 IP-only, IP/ESP and IP/UDP profiles,
    * interoperability: improve conformance to ROHC standards:
       * RFC3095: correctly handle the IR D flag of IP-only, UDP, ESP, and
         UDP-Lite profiles
       * RFC3843: add support for Static Chain Termination
    * preliminary Wireshark dissector in Lua
    * bug fixes:
      * TCP profile: do not skip MSN 65535 at compressor
      * Robustness of decompressor for TCP profile:
          * Context Replication: check whether base context does exist
            before using it 
          * avoid assertion at decompressor with malformed TCP options:
             * length of TCP options is not a multiple of 32-bit words
             * large TCP options > 40 bytes
          * handle length-changing generic TCP options
       * kernel:
          * fix 64-bit division
          * fix nonnull warnings
          * fix test application/script for Linux kernel module
       * sniffer:
          * handle packet timing so that context re-use works correctly
          * detect layer-3 protocol from Ethernet protocol type
    * Q&A:
       * fix compilation error when using gcc-7 
       * decrease code complexity
       * fix some spelling mistakes detected by codespell
    
    
    == Compatibility with previous releases ==
    
    From a ROHC protocol point of view, the 2.2.0 release is not compatible
    with previous releases if you use one of the ROHCv1 IP-only, ESP,
    UDP-Lite or UDP profiles. This is due to interoperability fixes (see
    changelog). In general, mixing major versions for compressor and
    decompressor is not recommended.
    
    The library API is compatible with versions 2.0.x and 2.1.x. Some
    headers/types/functions were however added or modified for ROHCv2.
    See the migration guide [1] for more details.
