0.1.0-beta6 'Leonard Shelby'

This is a breaking release, it is NOT backward compatible with 0.1.0-beta5. State files generated by earlier versions must be removed before starting the beta6 daemon.

Breaking changes

• Rename cascaded.service to cascade.service (#913 by @maertsen). If you
  are using systemd, you will need to refer to cascade instead of cascaded
  now.

New

• Purging of excess diffs. (#657 by @ximon18)
• Show persistence operations in cascade zone status. (#901 by
  @tertsdiepraam)
• Remove persisted zone files when a zone is removed. (#942 by @ximon18)

Bug fixes

• Persist the maintenance mode setting. (#900 by @tertsdiepraam)
• Use IDs to sort persisted diffs instead of file paths. (#907 by
  @tertsdiepraam, fixes #908)
• Improve DNS errors and add EDEs. In particular do not return NXDOMAIN for
  SOA queries when no zone data is available. (#934 by @Philip-NLnetLabs)
• Don't store references to non-existing loaded IXFR diffs. (#936 by @ximon18)
• During incremental signing, allow re-signing a zone whose SOA record is
  unchanged. (#940 by @Philip-NLnetLabs)
• Don't abort XFR transfers if the response buffer is full. (#941 by
  @ximon18)
• If a zone is reloaded, and is read from a zonefile or via AXFR, check whether
  the zone has changed and cancel the load operation if it has not. (#945 by
  @bal-e, fixes #937)
• Wrong serial requested from upstream via IXFR due to compaction bug.
  (#952 by @ximon18, fixes #948)
• Correctly restore SOAs for standalone diffs. (#955 by @bal-e,
  fixes #953)
• 'a patchset could not be applied' error during zone restoration.
  (#959 by @ximon18, fixes #956)
• Include DNSSEC records in the loaded zone when compacting.
  (#961 by @ximon18, fixes #960)

Other changes

• Improve memory use for unsigned data in incremental signing. (#866 by
  @Philip-NLnetLabs)
• Enhance signing tests. (#848, #946 by @Philip-NLnetLabs)
• Specify key roll strategies explicitly rather than using dnst keyset
  defaults. (#933 by @ximon18)
• Add some DEBUG and TRACE logging about IXFR outbound request activity.
  (#947 by @ximon18)

Documentation improvements

• RST markup fixes to systemd socket activation quick start notes. (#858 by
  @ximon18)
• Document key roll strategies used by Cascade. (#933 by @ximon18)

Known issues

• Removing a zone while an operation is ongoing (e.g. loading or signing) may
  cause Cascade to crash. In the next release, we will only allow zones in
  maintenance mode to be removed.
