mod_md v1.1.8

• new configuration directive "MDBaseServer on|off" to allow/inhibit management of the base
  server domains outside VirtualHosts. By default, this is "off", e.g. mod_md will not manage
  certificates or perform https: redirections on the base server. This follows the
  principle of least surprise.
• Fixed gcc warnings.

mod_md v1.1.7

• MDMustStaple was unable to create the necessary OpenSSL OBJ identifier on some platforms,
  possibly because this fails if the OID is already configured in openssl.cnf, see
  here.
• Two memory leaks in cert issuer and alt-names lookup eliminated by Yann Ylavic.
• Changing MDMustStaple triggers certificate renewal.

mod_md v1.1.6

• Fixing a bug when code in assert() checks is not executed.

mod_md v1.1.5

• Some attempts at code readability, increased logging level for fallback cert generation that
  was swept under the DEBUG carpet before.
• More verbosity when not handing out certificates, e.g. mod_ssl asks, but mod_md has no
  idea what it is talking about. Some people report misbehaviour here.
• Re-enabled support for md_get_credentials() function that was used in older mod_ssl
  patch, so that people with old patched servers get a chance to upgrade.

mod_md v1.1.4

• When ACME fails to authenticate your domain, the exact server answer is logged
  as error. This helps to find out the reason for the failed challenge, for example
  when ACME reports a 'Timeout' if it could not reach your server. Implements #70.

mod_md v1.1.3

• Fixed wrong mem pool use for auto-added server names.

mod_md v1.1.2

• The first configuration check was skipping parts that are needed, especially for new
  MDs, and crash if mod_ssl calls back "too early". Reverting that change.

mod_md v1.1.1

• Fixed backward compaitbility to '<ManagedDomain' configurations, used in pre v1.1.0 versions
  to continue working. Test case added.
• added httpd version checks to test cases that make use of 2.5.0 mod_ssl features. Tests now
  run clean against a 2.4.30 installation.

mod_md v1.1.0

• IMPORTANT: name change in configuration directives. The Apache team decided that the current
  names would confuse you, the users, and asked for a change. The old names are still working
  in this version, so you can safely upgrade.
  They will give warnings in the log and will disappear in the immediate future.
  • ManagedDomain is now MDomain
  • <ManagedDomain> is now <MDomainSet>

mod_md v1.0.7

• acme now follows "up" link headers to retrieve issuer certificate chain. This
  will lead to shorter chains as the "up" links will stop at the cert that browsers
  trust instead of always going to the topmost root.
  See letsencrypt/boulder#3259
• Fixed a missing argument in a debug log statement.
• removed old EXPERIMENTAL code for defaulting to Lets Encrypt staging area.
