   These security issues were fixed:

   - CVE-2018-14645: A flaw was discovered in the HPACK decoder what caused an
     out-of-bounds read in hpack_valid_idx() that resulted in a remote crash
      and denial of service (bsc#1108683)
   - CVE-2018-11469: Incorrect caching of responses to requests including an
     Authorization header allowed attackers to achieve information disclosure
     via an unauthenticated remote request (bsc#1094846).

   These non-security issues were fixed:

   - Require apparmor-abstractions to reduce dependencies (bsc#1100787)
   - hpack: fix improper sign check on the header index value
   - cli: make sure the "getsock" command is only called on connections

   - patterns: fix possible double free when reloading a pattern list
   - server: Crash when setting FQDN via CLI.

   - session: fix reporting of handshake processing time in the logs
   - stream: use atomic increments for the request counter
   - thread: implement HA_ATOMIC_XADD()
   - ECC cert should work with TLS < v1.2 and openssl >= 1.1.1
   - dns/server: fix incomatibility between SRV resolution and server state
   - hlua: Don't call RESET_SAFE_LJMP if SET_SAFE_LJMP returns 0.
   - thread: lua: Wrong SSL context initialization.
   - hlua: Make sure we drain the output buffer when done.
   - lua: reset lua transaction between http requests
   - mux_pt: dereference the connection with care in mux_pt_wake()
   - lua: Bad HTTP client request duration.
   - unix: provide a ->drain() function
   - Fix spelling error in configuration doc
   - cli/threads: protect some server commands against concurrent operations
   - cli/threads: protect all "proxy" commands against concurrent updates
   - lua: socket timeouts are not applied
   - ssl: Use consistent naming for TLS protocols
   - dns: explain set server ... fqdn requires resolver
   - map: fix map_regm with backref
   - ssl: loading dh param from certifile causes unpredictable error.
   - ssl: fix missing error loading a keytype cert from a bundle.
   - ssl: empty connections reported as errors.
   - cli: make "show fd" thread-safe
   - hathreads: implement a more flexible rendez-vous point
   - threads: fix the no-thread case after the change to the sync point
   - threads: add more consistency between certain variables in no-thread case
   - threads: fix the double CAS implementation for ARMv7
