+ANSI escape charactor sequences may now be printed to the stderr stream.

+
+The function `epicsStrnGlobMatch(char* str, size_t len, char* pattern)`

+### Timeouts for Unit Test Programs
+
+The unit test programs that are run by the `make runtests` or `make tapfiles`
+commands get executed by a `.t` wrapper script which is normally generated by
+the EPICS `makeTestfile.pl` program. Those generated wrapper scripts now
+impose a time-limit on the test program they execute, and will kill it if it
+runs for longer than 500 seconds (8 minutes 20) without exiting. That
+time-limit can be changed for any such test by modifying the Makefile which
+creates and runs the `.t` wrapper script.
+
+Setting the environment variable `EPICS_UNITTEST_TIMEOUT` to the desired
+number of seconds while the Makefile is generating the test script changes the
+timeout in that script. For example:
+
+```
+  TESTSCRIPTS_HOST += hourLongTest.t
+  hourLongTest.t: export EPICS_UNITTEST_TIMEOUT=3600
+```
+
+When selecting such a timeout remember that different Continuous Integration
+systems such as GitHub Actions and Appveyor run on processors with different
+speeds, so allow enough head-room for slower systems to complete the test.
+
+Test programs written directly in Perl as a `.plt` script should implement a
+similar timeout for themselves. The "netget" test in Base does this in a way
+that works on Windows as well as Unix-like hosts.
