+
+## Changes made on the 7.0 branch since 7.0.5
+
+<!-- Insert new items immediately below here ... -->
+
+### epicsEnvShow accepts glob pattern
+
+The optional argument to epicsEnvShow can now be a glob pattern.
+
+### New function `epicsStrnGlobMatch()`
+
+The function `epicsStrnGlobMatch(char* str, size_t len, char* pattern)`
+works exactly the same as `epicsStrGlobMatch()` but takes an additional
+length arguments which limits the number of characters of `str` to match.
+
+### Glob pattern allowed in `var` command
+
+When used with one argument, the `var` command can be used with a glob pattern
+for printing matching variables.
+
+### Fix for input links marked "special"
+
+The calcout record (and a number of synApps record types) marks its input
+link fields with the attribute `special(SPC_MOD)` and provides code in
+the record's `special()` routine to reinitialize the related value field
+whenever the input link field is set to a numeric constant. Unfortunately the
+changes to the link handling code broke this behaviour (reported as Launchpad
+[bug #1824277](https://bugs.launchpad.net/epics-base/+bug/1824277))
+back in the Base 3.16.1 release. This issue has been fixed in Base, although
+external record types may require some fixing to ensure they are correctly
+checking for and initializing the link in their `special()` routine.
+
+### IOCsh sets `${PWD}`
+
+IOC shell will now ensure `${PWD}` is set on startup,
+and updated by the `cd` iocsh function.
+
+
+### 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.
