- Use a Sphinx/Myst {include} directive to pull the text from all previous
RELEASE files into the output, which makes the website sidebar index work
properly.
- Exclude the RELEASE files from the files given to RTD to publish, they
aren't needed now and generate warnings if included.
- Updated the intro paragraph in all RELEASE files.

# Release Notes
|
|
|
|
This document describes the changes that were included in the release of EPICS
|
|
noted below. Release entries are now provided in a separate document for each
|
|
version in the EPICS 7 series, but all are combined into a single page for
|
|
publishing on the EPICS website. Separate release documents are also included
|
|
from the older Base 3.15 and 3.16 series.
|
|
|
|
The external PVA submodules continue to maintain their own release notes files
|
|
as before, but the entries describing changes in those submodules since version
|
|
7.0.5 have been copied into the associated EPICS Release Notes files, and will
|
|
be added to new EPICS Release Notes published in the future.
|
|
|
|
## EPICS Release 7.0.6.1
|
|
|
|
### `mbboDirectRecord` enhancements
|
|
|
|
The bit fields `B0` - `B1F` of this record are now always updated and have a
|
|
monitor posted when the `VAL` field is set and the record processed. It is now
|
|
possible to initialize the record's value by setting the bit fields inside a
|
|
database file as long as no other method was used to initialize it (suc as
|
|
setting `VAL` directly, using `DOL`, or by an initial readback from device
|
|
support). A new internal field `OBIT` was added to store information about
|
|
monitors posted on the bit fields.
|
|
|
|
### Minimum Perl Version is now 5.10.1
|
|
|
|
Some scripts now make use of features that were introduced to this Perl version
|
|
that was released in 2009.
|
|
|
|
### DB Links to `DBF_MENU` fields fixed
|
|
|
|
[GH:183](https://github.com/epics-base/epics-base/issues/183)
|
|
These were broken in a previous release, but now work again.
|
|
|
|
### Long String access to CALC fields fixed
|
|
|
|
[GH:194](https://github.com/epics-base/epics-base/issues/194)
|
|
This was broken in a previous release, but now works again.
|
|
|
|
### Minor Changes
|
|
|
|
+ Many code comments have been spell-checked and corrected.
|
|
+ Passing a `-DDEBUG` compiler flag no longer breaks the build.
|
|
+ Parallel builds of RTEMS-mvme2100 and RTEMS-mvme2700 targets now work.
|
|
+ Illegal characters seen in JSON strings in a database file should now get a
|
|
better error message.
|
|
|
|
### Other Launchpad Bugs and GitHub Issues Fixed
|
|
|
|
+ [lp:1938459](https://bugs.launchpad.net/epics-base/+bug/1938459)
|
|
[GH:191](https://github.com/epics-base/epics-base/pull/191) int64in only
|
|
checks lower 32 bits for change
|
|
+ [lp:1941875](https://bugs.launchpad.net/epics-base/+bug/1941875) Buggy
|
|
warning message "Record/Alias name '...' should not contain non-printable ...
|
|
+ [GH:187](https://github.com/epics-base/epics-base/issues/187) waveformRecord
|
|
missing PACT=true?
|
|
+ [GH:189](https://github.com/epics-base/epics-base/pull/189) Fix a couple
|
|
memory leaks and a segfault
|
|
+ [GH:200](https://github.com/epics-base/epics-base/pull/200) and
|
|
[GH:201](https://github.com/epics-base/epics-base/pull/201) Fix timers on MS
|
|
Windows for non-EPICS threads
|
|
|
|
### Compiler interface for epicsAtomic tidied up
|
|
|
|
[GH:192](https://github.com/epics-base/epics-base/pull/192)
|
|
Both GCC and CLANG compiler intrisics used for the epicsAtomic APIs have been revised; implementations using CLANG should now run faster as they now use the compiler's built-in atomic functions instead of taking a mutex.
|
|
|
|
### The epicsTime code has been reimplemented
|
|
|
|
[GH:185](https://github.com/epics-base/epics-base/pull/185)
|
|
This was done to simplify the code and may have improved performance slightly for some uses. Support for the old NTP-specific `struct l_fp` has been dropped but all other routines and methods of the `class epicsTime` function as before.
|
|
|
|
### Updates to Record Reference documentation
|
|
|
|
Many of the built-in record types have had improvements to their documentation with additional fields added to the tables, rewrites of descriptions and links to other documents added or fixed.
|
|
|
|
### Submodule updates
|
|
|
|
The pvAccess module was updated to version 7.1.4:
|
|
|
|
- Changes to caProvider
|
|
- Resolve issues with pv structures that don't have a value field
|
|
- Add NULL checks for handling unusual structures
|
|
- Speed up channel creation when using large numbers of channels
