+
+### bi "Raw Soft Channel" use MASK
+
+If MASK is non-zero, The raw device support will now apply MASK to the
+value read into RVAL.
+eg. allows extraction of a bit from an input integer.
+
+```
+record(longin, "integer") {
+    field(VAL, "0xff")
+}
+record(bi, "bit1") {
+    field(DESC, "extract bit 1")
+    field(DTYP, "Raw Soft Channel")
+    field(INP , "integer")
+    field(MASK, "0x2")
+    field(ZNAM, "Clear")
+    field(ONAM, "Set")
+}
+```
+
+### 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.
+
+```
+record(ai, "myrec") {}
+```
+
+`dbRecordsOnceOnly!=0` previously disallowed appending fields with either form:
+
+```
+record("*", "myrec") {} # error
+record(ai, "myrec") {}  # error
+```
+
+Beginning with this release, `dbRecordsOnceOnly!=0` allows appending when explicitly intended (when record type is `"*"`).
+
+```
+record("*", "myrec") {} # allowed
+record(ai, "myrec") {}  # error
+```
+
+### Add `$EPICS_CLI_TIMEOUT`
+
+Add support for CA tools timeout from environment variable `$EPICS_CLI_TIMEOUT`
+which sets the default the default timeout for `caget` et al.
+The `-w` argument continues to take precedence.
+
+### Fixed leak from a non-EPICS thread on WIN32
+
+On Windows targets, if a thread not created by `epicsThreadCreate*()` directly
+or indirectly calls an `epicsThread*()` function, a specific tracking struct
+is allocated.  Prior to this release the allocation would not be `free()`d,
+resulting in a memory leak.
+
+A similar issue on POSIX targets was previously fixed.
+
+### Change compiler for FreeBSD to clang
+
+The default compiler for FreeBSD targets changes from GCC to clang.
+
+### Expose `dbCreateAlias` in IOC shell
+
+Add a new IOC shell command `dbCreateAlias` allow record aliases to be added.
+Intended for use before `iocInit`.  eg. to add an alias "bar" for a record "foo".
+
+```
+dbLoadRecords("some.db") # includes: record(ai, "foo") { ...
+dbCreateAlias("foo", "bar")
+iocInit()

-This filter replaces the timestamp in the data fetched through the channel with
-the time the value was fetched (or an update was sent). The record's timestamp
+This filter is used for two purposes:
+
+=over
+
+=item * to retrieve the timestamp of the record as a value in several different
+        formats;
+
+=item * to retrieve the record value as normal, but replace the timestamp with

+
+=head4 Parameters
+
+=head4 No parameters (an empty pair of braces)
+
+Retrieve the record value as normal, but replace the timestamp with the time the
+value was fetched (or an update was sent). This is useful for clients that can't
+handle timestamps that are far in the past. Normally, the record's timestamp
 indicates when the record last processed, which could have been days or even
 weeks ago for some records, or set to the EPICS epoch if the record has never
 processed.
 
-=head4 Parameters
+=head4 Numeric type C<"num">
 
-None, use an empty pair of braces.
+The following values are accepted for this parameter:

+=item * C<"dbl"> requests the timestamp as C<epicsFloat64> representing the
+        non-integral number of seconds since epoch. This format is convenient,
+        but loses precision, depending on which epoch is used.
+
+=item * C<"sec"> requests the number of seconds since epoch as C<epicsUInt32>.
+
+=item * C<"nsec"> requests the number of nanoseconds since epoch as
+        C<epicsUInt32>.
+
+=item * C<"ts"> requests the entire timestamp. It is provided as a two-element
+        array of C<epicsUInt32> representing seconds and nanoseconds.
+
+=back
+
+Note that C<epicsUInt32> cannot be transferred over Channel Access; in that
+case, the value will be converted to C<epicsFloat64>.

+
+The following values are accepted for this parameter:
+
+=over
+
+=item * C<"epics"> requests the timestamp as a string in the format used by

+
+The following values are accepted for this parameter:
