Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Revised automatic setpoint change. The proposed approach is essentially the approach used by most controllers of eCCR ('upshift' on descent, 'downshift' on ascent), so that the OSTC4 when used as a backup computer for eCCR will make the changes at the same time as the eCCR itself.
