+### DBE_PROPERTY event rate changed
+
+Updating property fields now only post DBE_PROPERTY events if the
+field actually changed.
+
+### Allow users to delete previously created records from the database
+
+From this release, record instances and aliases that have already been loaded
+by an IOC can be removed from the database again before the call to iocInit
+by loading a second instance of the named records but using `"#"` in place of
+the record type. Values for the fields are not required or advised, just use
+an empty record body { }. This is useful when a template defines records that
+are not wanted in some IOCs, without having to split or duplicate the original
+template.
+
+For example this will remove the record named "unwanted":
+
+```
+record("#", "unwanted") { }
+```
+
+## EPICS Release 7.0.8.1
+
+### Limit to `_FORTIFY_SOURCE=2`
+
+GCC versions 12 and beyond and glibc have added some aggressive runtime
+checks for buffer overflows in libc functions at runtime, and the
+[Ubuntu 2024.04](https://wiki.ubuntu.com/ToolChain/CompilerFlags) release
+increased their default gcc fortification level from 2 to 3.
+This has started causing EPICS Base builds to fail on that version, and
+other OS releases may make that configuration change with similar results.
+This release detects a compiler configured with `_FORTIFY_SOURCE=3` and
+overrides it to 2.
+Later releases of Base will adjust the code, providing information to the
+compiler to avoid triggering these incorrect protections.
+
+### Fix issue with compress record
+
+In Base 7.0.8, an update to the compress record was added to allow for certain
+algorithms to use partially filled buffers in their computations. Unfortunately,
+this broke the behaviour of the records in certain cases. This has been fixed.
+
+### Various minor changes
+
+These included fixing minor memory leaks and documentation corrections. The
+`SIZV` field of lsi, lso and printf record VAL fields now can't exceed 32767
+characters, to match an internal limit.
+
+### `epicsSocketAccept()` now returns `SOCKET`, not `int`
+
+This might have some effect on downstream modules still using `int`, but the
+OS-specific osdSock.h headers which osiSock.h includes have all declared
+`SOCKET` (in most casese as a typedef for `int`) for many releases.
+This change removes a compiler warning on WIN32.
+Further details and the discussion about this change can be found
+[here](https://github.com/epics-base/epics-base/pull/458).
+
+### `dbLoadRecords` allows macros with default values
+
+Previously the parser assumed that files containing macro substitutions were
+bad if no macro definitions were provided; that assumption was made incorrect
+once macro substitutions were allowed to provide a default value.
+
+### Hostname length limit in CA removed
+
+Before this release, the CA client library only handled hostnames in address
+list environment variables up to 255 characters long.
+This limit has been removed.

-### ANSI escapes in stderr
-
-ANSI escape charactor sequences may now be printed to the stderr stream.
-These escapes will appear in logs captured from that stream.
-Tools which parse and/or render these logs may need to be adjusted to
-either strip out the escapes, or to translate them into markup.
-(see [ansi2html](https://pypi.org/project/ansi2html/) for example)

-### Allow explicit append with `dbRecordsOnceOnly!=0`

-Previously setting `dbRecordsOnceOnly!=0` prevented any further changes to a record via a .db file.  eg.

-`dbRecordsOnceOnly!=0` previously disallowed appending fields with either form:

-### Fix for input links marked "special"

-The calcout record (and a number of synApps record types) marks its input

-### 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.
