    Release Notes: This release fixes the TSIG validation code that contained a possible weakness in the digest comparison. This has no huge security impact, but was worth fixing as soon as possible.

    •  02 Apr 2014 07:39

      Release Notes: This release adds bugfixes, support for including a whole directory in 1.4.3, logging of remote control commands, a more lightweight "knotc reload" which doesn't reload unchanged zones, and "knotc -f refresh" to force zone retransfers in 1.4.4.

      •  06 Jan 2014 13:53

        Release Notes: The most important highlight in this release is the automatic DNSSEC signing (a technology preview). It also reduces the memory footprint (up to 35% for large zones).

        •  16 Dec 2013 11:44

          Release Notes: This release candidate added IDN support in Knot utilities, and in DNSSEC, support for the GOST algorithm. A crash in additional section processing, a race condition in event cancellation, journal corruption after failed transactions, and detection of ECDSA support for DNSSEC were identified and fixed. Memory consumption was optimized even more, and DNS Server Benchmarks (results and source code) were released.
