   An update that fixes two vulnerabilities is now available.

Description:

   This update for rxvt-unicode fixes the following issues:

   Update to 9.26

   - ev_iouring.c was wrongly required during compilation, and wrongly not
     packaged.

   Update to 9.25 (boo#1186174 CVE-2021-33477)

   - for the 17.5th anniversary, and because many distributions seem to
     remove rxvt in favour of urxvt, this release resurrects rclock as
     urclock.
   - add support for systemd socket-based activation - debian bug #917105,
     freebsd bug #234276.
   - do not destruct perl on exit anymore: this might fail for a variety of
     reasons, and takes unneccessary time.
   - remove any macros from urxvtperl manpage(s), should fix debian bug
     858385.
   - the old bg image resources are now provided by the background extension,
     and perl is thus required for bg image support. No configuration change
     is needed: urxvt autoloads the background ext if any bg image
     resource/option is present (for OSC sequences to work you need to enable
     it explicity). The old bg image resources are also now deprecated; users     are encouraged to switch to the new bg image interface (see man
     urxvt-background).
   - confirm-paste now checks for any ctlchars, not just newlines.
   - searchable scrollback will now ignore bracketed paste mode sequences
     (prompted by Daniel Gröber's patch).
   - drop ISO 2022 locale support. ISO 2022 encodings are not supported in
     POSIX locales and clash with vt100 charset emulation (the luit program
     can be used as a substitute).
   - perl didn't parse rgba colours specified as an array correctly,
     only allowing 0 and 100% intensity for each component (this affected
      fill and tint).
   - when iterating over resources, urxvt will now try to properly handle
     multipart resources (such as "*background.expr"), for the benefit
     of autoloading perl extensions.
   - ESC G (query rxvt graphics mode) has been disabled due to security
     implications. The rxvt graphics mode was removed in rxvt-unicode 1.5,
     and no programs relying on being able to query the mode are known.
   - work around API change breakage in perl 5.28, based on a patch by Roman
     Bogorodskiy.
   - improved security: rob nation's (obsolete) graphics mode queries no
     longer reply with linefeed in secure/default mode.
   - ISO 8613-3 direct colour SGR sequences (patch by Fengguang Wu).
   - xterm focus reporting mode (patch by Daniel Hahler).
   - xterm SGR mouse mode.
   - implement DECRQM. Patch by Přemysl Eric Janouch.
   - add missing color index parameter to OSC 4 response. Patch by Přemysl
     Eric Janouch.
   - in some window managers, if smart resize was enabled, urxvt erroneously
     moved the window on font change - awesome bug #532, arch linux bug
     ##34807 (patch by Uli Schlachter).
   - fix urxvtd crash when using a background expression.
   - properly restore colors when using fading and reverse video is enabled
     while urxvt is focused and then disabled while it is not focused, or
     vice versa (patch by Daniel Hahler).
   - fix high memory usage when an extension repeatedly hides and shows an
     overlay (reported by Marcel Lautenbach).
   - expose priv_modes member and constants to perl extensions (patch by
     Rastislav Barlik).
   - fix a whole slew of const sillyness, unfortunately forced upon us by ISO
     C++.
   - update to libecb 0x00010006.
   - disable all thread support in ecb.h as we presumably don't need it.
   - slightly improve Makefile source dependencies.
   - work around bugs in newer Pod::Xhtml versions (flags incorrect
     formatting codes in xhtml/html sections but does not interpret correct
     ones).
   - New file: /usr/bin/urclock
   - restore the -256color binaries
