## Changes made on the 7.0 branch since 7.0.7
<!-- Insert new items immediately below here ... -->
### Extend longout conditions to write the OUT link (OOPT field)
The longout record has now the capacity to condition its output write operation to
different options, using the OOPT field (similar to calcout record). This is
the first output record to have such feature as a result of the
[Make output records only write on change](https://bugs.launchpad.net/epics-base/+bug/1398215)
issue on Launchpad.
### Add conditional output (OOPT) to the longout record
The longout record can now be configured using its new OOPT and OOCH fields
to (not) write to its output link depending on the contents of VAL, in a
similar manner to the calcout record. More information can be found on the
reference page for the longout record type that accompanies this release.
This functionality was suggested in
[lp# 1398215](https://bugs.launchpad.net/epics-base/+bug/1398215) and may
be added to other output record types if the community finds it useful,
please send feedback about the feature to tech-talk.
### Tab completion for IOC shell
