  ## Release 1.8.1
  
   * Fix --enable-thread-safety-constructor configure option
  
  ## Release 1.8
  
   * Add --enable-thread-safety-constructor configure option (default: enabled)
     to call XInitThreads() from the library's constructor, thus enabling
     thread-safety and locking by default.  This may expose bugs in clients
     which did not follow documented rules for calling libX11 functions.
   * Fix Ethopian (am_ET.UTF-8) compose sequences.
   * Remove 8 compose sequences that generated the input symbols.
   * Add compose seuences for abovedot (\<period\> \<space\>),
     diaeresis (\<quotedbl\> \<space\>), and ogonek (\<semicolon\> \<space\>).
  
  ## Release 1.7.5
  
   * Avoids a segfault when an invalid name is used for opening a display.
  
  ## Release 1.7.4
  
   * Fixes the "Unknown sequence number" error by allowing backward jumps
     in the sequence number when widening it.
   * Any changes to virtual modifiers get propagated properly.
   * Greek case-conversion tables were updated to Unicode Data 14.0.
   * Compose sequences for  ☮  🄯  ⇐  ⇑  ⇓  were added,
     being the following: OY, ()), =<, =^, and =v.
   * Hammer-and-sickle can be composed with question mark plus backslash.
  
  ## Release 1.7.3
  
   * Fixes a hanging issue in _XReply() where the replying thread would
     wait for an event when another thread was already waiting for one.
   * Avoids a crash when the X connection gets broken while closing down.
  
  ## Release 1.7.2
  
  This is a bug fix release, correcting a regression introduced by and
  improving the checks from the fix for CVE-2021-31535.
  
  ## Release 1.7.1
  
  This is a bug fix release, including a security fix for
  CVE-2021-31535, nls and documentation corrections.
  
   * Reject string longer than USHRT_MAX before sending them on the wire
   * Fix out-of-bound access in KeySymToUcs4()
   * nls: allow composing all breved letters also with a lowercase "u"
   * nls: add 'C.utf8' as an alias for 'en_US.UTF-8'
   * Nroff code fixes
   * Comments fixes
  
  ## Release 1.7.0
  
  Version 1.7.0 includes a new API, hence the change from the 1.6 series
  to 1.7:
  
   * XSetIOErrorExitHandler which provides a mechanism for applications
     to recover from I/O error conditions instead of being forced to
     exit. Thanks to Carlos Garnacho for this.
  
  This release includes a bunch of bug fixes, some of which have been
  pending for over three years:
  
   * A bunch of nls cleanups to remove obsolete entries and clean up
     formatting of the list. Thanks to Benno Schulenberg for these.
  
   * Warning fixes and other cleanups across a huge swath of the
     library. Thanks to Alan Coopersmith for these.
  
   * Memory allocation bugs, including leaks and use after free in the
     locale code. Thanks to Krzesimir Nowak, Jacek Caban and Vittorio
     Zecca for these.
  
   * Thread safety fixes in the locale code. Thanks to Jacek Caban for
     these.
  
   * poll_for_response race condition fix. Thanks to Frediano Ziglio for
     the bulk of this effort, and to Peter Hutterer for careful review
     and improvements.
  
  Version 1.7.0 includes a couple of new locales:
  
   * ia and ie locales. Thanks to Carmina16 for these.
  
  There are also numerous compose entries added, including:
  
   * |^ or ^| for ↑, |v or v| for ↓, ~~ for ≈. Thanks to Antti
     Savolainen for this.
  
   * Allowing use of 'v' for caron, in addition to 'c', so things like
     vC for Č, vc for č. Thanks to Benno Schulenberg for this.
  
   * Compose sequences LT, lt for '<', and GT, gt for '>' for keyboards
     where those are difficult to access. Thanks to Jonathan Belsewir
     for this.
