Comment (by Bruce Dubbs):

 * Noteworthy changes in release 4.11.0 (2026-07-11) [stable]

 ** Bug Fixes

   find no longer crashes when diagnosing a directory cycle (without a
 symlink
   being involved pointing to a parent directory).
   [Bug present since the FTS implementation.]

   'find -used' now behaves correctly on OpenBSD 7.8 with difftime(3)
 underflow
   bug in the C library (already fixed there) when the access time of a
 file is
   identical to its change time.

   'find -ignore_readdir_race' now better handles races between FTS reading
 a
   directory and visiting its entries when the file or directory was
 meanwhile
   removed.

   To fix a POSIX compatibility bug, -exec foo Z{} + is no longer a
   complete predicate, because '+' is only a terminator when it follows
   an argument which is exactly '{}'.  The findutils documentation
   already states this, and now find's behaviour matches the
   documentation.

   'updatedb.sh' now properly handles the variables for the 'find' and
 'frcode'
   utilities, and hence avoids command injection.

 ** Changes in find

   As announced since the release of 4.7.0 (2019) and mandated by POSIX
 2024,
   the behaviour of the -mount option changed: while it was a mere alias
 for
   the -xdev option to prevent descending into directories of another
 device,
   the -mount option now makes find(1) ignore files on another device,
 i.e.,
   'find -mount' will skip the entry of active mount points already.
   Example, assuming the PROC filesystem is mounted on '/proc':
 {{{
     $ find / -mount -path /proc -print
     $ find / -xdev -path /proc -print
     /proc
 }}}
   The actions -execdir and -okdir now refuse the '{}' replacement in the
 zeroth
   argument of the command to be run.  While POSIX allows this for -exec,
 this is
   deemed insecure as an attacker could influence which files could be
 found.

   'find -regex' with the default or the 'emacs' regextype now aligns
 better with
   Emacs behaviour, and therefore e.g. supports character classes:
 {{{
     $ touch 123 && find -regex './12[[:digit:]]'
     ./123
 }}}
   find now issues a warning when the punctuation operators '(', ')', '!'
 and ','
   are passed with a leading dash, e.g. '-!'.  Future releases will not
 accept
   that any more.  Accepting that was rather a bug "since the beginning".

 ** Improvements

   xargs now gives a better error diagnostic when executing the given
 command
   failed.

 ** Documentation Changes

   The most recent version of the POSIX standard (IEEE Std 1003.1-2024,
   also known as The Open Group Base Specifications, Issue 8) has
   standardised "find -print0" and "xargs -0".  Our documentation now
   points this out.  Similarly for 'find -iname'.

   The code example for "Finding the Shallowest Instance" in the Texinfo
 manual
   and the corresponding one in the EXAMPLES section in the find.1 man page
 have
   been fixed.

   Translators contributed numerous fixes for issues in the find.1 man
 page.

   The list of actions that suppress the default -print action has been
   supplemented with the missing '-print0' and '-fprint0' actions.

   The manual pages have been updated to give better and/or more
   consistent output with manpage formatters other than GNU roff.

 ** Translations

   Updated the following translations:
   Arabic, Brazilian Portuguese, Bulgarian, Chinese (simplified), Croatian,
   Czech, Dutch, Estonian, French, German, Indonesian, Korean, Polish,
   Portuguese, Romanian, Spanish, Swedish, Ukrainian.

 ** Future Changes

   A future release will remove the warning message find prints about
   the 2007 change in the meaning of "-perm /000".  Everybody who is
   likely to care probably knows about this change by now.
