NEWS since v2.7.6 (2018-02-03):

* The --follow-symlinks option now applies to output files as well as input.
* 'patch' now supports file timestamps after 2038 even on traditional
  GNU/Linux platforms where time_t defaults to 32 bits.
* 'patch' no longer creates files with names containing newlines,
  as encouraged by POSIX.1-2024.
* Patches can no longer contain NUL ('\0') bytes in diff directive lines.
  These bytes would otherwise cause unpredictable behavior.
* Patches can now contain sequences of spaces and tabs around line numbers
  and in other places where POSIX requires support for these sequences.
* --enable-gcc-warnings no longer uses expensive static checking.
  Use --enable-gcc-warnings=expensive if you still want it.
* Fix undefined or ill-defined behavior in unusual cases, such as very
  large sizes, possible stack overflow, I/O errors, memory exhaustion,
  races with other processes, and signals arriving at inopportune moments.
* Remove old "Plan B" code, designed for machines with 16-bit pointers.
* Assume C99 or later; previously it assumed C89 or later.
* Port to current GCC, Autoconf, Gnulib, etc.
