  • v1.1.2-rc1
    Knot DNS v1.1.2-rc1
    -------------------
    
    Bugfixes:
    	* Fixed crash on reload when config contained duplicate zones.
    	* Fixed scheduling of transfers.
  • v1.1.1
    d5898def · Switched version to 1.1.1 ·
    Knot DNS v1.1.1
    ---------------
    
    Bugfixes:
            * Fixed assertion failing when asking directly for a wildcard name.
  • v1.1.1-rc1
    Knot DNS v1.1.1-rc1
    -------------------
    
    Bugfixes:
            * Crash after IXFR in certain cases when adding RRSIG in an IXFR.
            * Fixed behaviour when incoming IXFR removes a zone cut. Previously
              occluded names now become properly visible. Previously lead to a
              crash when the server was asked for the previously occluded name.
            * Fixed handling of zero-length strings in text zone dump. Caused the
              compilation to fail.
            * Fixed TSIG algorithm name comparison - the names should be in
              canonical form.
            * Fixed handling unknown RR types with type less than 251.
    
    Features:
            * Improved compression of packets. Out-of-zone dnames present in RDATA
              were not compressed.

              contain the CNAME.
            * Malformed packets parsing.
            * Failed IXFR caused memory leaks.
            * Failed IXFR might have resulted in inconsistent zone structures.
            * Fixed answering to +dnssec queries when NSEC3 chain is corrupted.
            * Fixed answering when transitioning from NSEC3 to NSEC.
            * Fixed answering when zone contains multiple NSEC3 chains.
            * Handling RRSets with different TTLs - TTL from the first RR is used.
            * Synchronization of zone reload and zone transfers.
            * Fixed build on NetBSD 5 and FreeBSD.
            * Fixed binding to both IPv4 and IPv6 at the same time on special
              interfaces.
            * Fixed access rights of created files.
