## Changes made on the 7.0 branch since 7.0.7
### 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()
```
### dbEvent eventsRemaining missed on cancel
In some cases, RSRV may queue a subscription update, but not flush it.
@@ -48,6 +72,23 @@ The compress record now supports the use of partially-filled buffers when using
any of the N-to-one algorithms. This is achieved by setting the new field `PBUF`
to `YES`.
### Extended timestamp channel filter
The `"ts"` filter can now retrieve the record's timestamp in several numeric
and string formats, some of which support full nanosecond precision.

### Fixed leak from a non-EPICS thread
On some 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, on POSIX and WIN32 targets, this
allocation would not be `free()`d, resulting in a memory leak.

MSVC before vs2012, and the WINE runtime).

This now works again, it was broken in 2019 (7.0.3.1) by an errant commit.

=head3 TimeStamp Filter C<"ts">
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
the time the value was fetched.
=back
=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:
=head4 Example
=over
Hal$ caget -a 'test:channel.{"ts":{}}'
test:channel.{"ts":{}} 2012-08-28 22:10:31.192547 0 UDF INVALID
Hal$ caget -a 'test:channel'
test:channel <undefined> 0 UDF INVALID
=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>.
=head4 String type C<"str">
The following values are accepted for this parameter:
=over
=item * C<"epics"> requests the timestamp as a string in the format used by
tools such as C<caget>.
=item * C<"iso"> requests the timestamp as a string in the ISO8601 format.
=back
=head4 Epoch adjustment C<"epoch">
The following values are accepted for this parameter:
=over
=item * C<"epics"> keeps the EPICS epoch (1990-01-01) and is the default if the
C<"epoch"> parameter is not specified.
=item * C<"unix"> converts the timestamp to the UNIX/POSIX epoch (1970-01-01).
