mod_md v2.2.5

• Corrected a check when OCSP stapling was configured for hosts
  where the responsible MDomain is not clear, by Michal Karm Babacek (@Karm).
• @uhliarik added documentation for the a2md command. Use xmlto man ./a2md.xml to generate it.
• Softening the restrictions where mod_md configuration directives may appear. This should
  allow for use in If and Macro sections. If all possible variations lead to the configuration
  you wanted in the first place, is another matter.

mod_md v2.2.4

• Fixed a compile time issue with OpenSSL 1.0.2 in the new OCSP code.
• Skip port checks for domain server_rec selection when "tls-alpn-01" is configured
  explicitly (related to #133). [@mkauf]
• Added a sample scripts/md_message.sh on how to use MDMessageCmd.

mod_md v2.2.3

• Configuring MDCAChallenges replaces any previous existing challenge configuration. It
  had been additive before which was not the intended behaviour. [@mkauf]
• Fixing order of ACME challenges used when nothing else configured. Code now behaves as
  documented for MDCAChallenges. Fixes #156. Thanks again to @mkauf for finding this.
• Added a script - inspired by curl https://github.com/curl - that collects contributors
  from the git commits and PRs. Adding a "Thanks" section with their names in the README.md.

mod_md v2.2.2

• Fixing a potential, low memory null pointer dereference [thanks to @uhliarik].
• Fixing an incompatibility with a change in libcurl v7.66.0 that added unwanted
  "transfer-encoding" to POST requests. This failed in directy communication with
  Let's Encrypt boulder server (however it worked when accessed via the hosting CDN,
  as almost all live usages do). Thanks to @mkauf for finding and fixing.
• Fixes a compiler warning. False flag, but initialization to make it happy does not hurt.
  Thanks to @sundayoyeniyi for finding this. Refs #154.

mod_md v2.2.0

• No longer beta status
• Synched with Apache trunk and planned for 2.4.x backport when all works well there
• Re-importing of log tags assigned in Apache project
• Some documentation clarifications
• New OCSP Stapling implementation
• Various improvements and fixes during v2.1.x development. See ChangeLog for details

mod_md v2.1.10 (annoyingly still beta)

• if 'MDBaseServer' in enabled and there is no specific VirtualHost for a domain, the
  base server config is considered the relevant one for deciding ACME support. This
  is most relevant for the 'tls-alpn-01' challenge, see issue #150).
• MDMessageCmd is now invoked with 'installed' when the certificate is actually becoming
  active at server startup/reload. Different to all other messages, this one is invoked
  while the server is still root and has according privileges. (Hint: you may use this
  to copy a certificate+key to another application's preferred location/format.)

mod_md v2.1.9 (almost not beta)

• server-status no longer leaves the "activity" column empty when a renewal is ongoing.
• server-status activity: report a renewal as "pending" when it is due but no job has been
  started yet.
• removed the "valid after" time as this was confusing. The new certificate is already
  valid, only it is recommeneded to wait with the actication a bit. Admins are probably
  better aware what the clock skew requirements of their site are.

mod_md v2.1.8 (just a touch of beta)

• Some notifications cleanups:
  • notifications about errors no longer change the status of the ongoing renewal.
  • notifications about a successful renewal are re-attempted on failure, just like
    other failures cause a retry with a backing-off delay.
  • warnings about expiring certificates are only sent, if there is no renewal
    already done (but maybe not activated yet) for a domain
  • failure to notify about expiring certficates also cause retry and are cleared
    when/if finally successful.

mod_md v2.1.7 (beta almost over)

• Changed server-status section headings to make more clear what is listed there.
• no longer listing the logs in the top-level md-status handler (where all managed
  domains are listed). Getting the status of a particular domain has the log).
• fixing some signedness warnings in clang 11.
• Fixes bug in time period calculation for removing old OCSP response files.

mod_md v2.1.6 (beta)

• Fixed issue #145 where a server restart was not done when recommended and checking
  becamed called in a tight loop, eventually calling message commands again and again.
  Test case added for this.
• 'make test' will now trigger the build if not done before. removed some obsolete
  test special targets.
• starting to integrate with travis for build and test coverage
• documented how MDCAChallenges now overrides any port sanity checks.
