### Calibrations

- Note: Changes to the license handling means that calibration files (other than the DEMO calibration) can no longer be edited offline without a license.
- Extended Limits Mode: pop up message if limits have been violated & prevent editing out of range.
    Added Extended Limits mode that must be enabled in order to set values outside of their typical range (up to either their extended limits or full-scale if extended limits were not specified in the ECU Defintion file).
- Added Reset to default value context menu command for selected options.
- Default values now take into account bit masks.
- Per-object reset to defaults (if available).

- New Calibration: persist window geometry.
- Fixed entry of single digit numbers for parameters/options via keyboard.
- Fixed issue with sign extension of raw values.

- Defer compare so that view updates before running the compare algorithm.
- Removed 'calibration compare wizard'.
- Use square brackets instead of curly braces to indicate item units as per convention.
- Fixed directory lists so that templates are picked up from "Documents/*vendor*/*app*/conversion templates".
- Fixed issue saving conversion templates with more recent ECU definition file versions.
- Fixed bug in display of verification differences - source values were always 0.
- Fixed issues with default filename.
- Fixed calibration compare crash.
- Fixed File->Convert unhandled exception if the file cannot be opened.
- Fixed crash in Compare tab when multi-differences report is shown and then a new compare is loaded that cleared it.

- Workarounds for comms issues with SL1:
  - LOGTBL reads always return 8 bytes from SL1, leading to verify errors.
  - LOGTBL reads are now prevented from exceeding the max transfer size of the port.
  - SL1 incorrectly specified protocol read/write sizes in the ECU definition file, leading to undesired effects.
- Handle new PCAN_ERROR_CAUTION initialization result code which means the port was still initialized (and would have undesirable knock-on effects).

- Auto-close start dialog if starting an ECU comms operation.
- If showing a new ECU transaction progress dialog, close any completed ones first.
- Reworked comms notification processing slightly to avoid situation where disconnecting the ECU could result in the disconnected state not being seen.
- Added 'Change Connection...' button to Connect dialog.  When connecting to an ECU if the incorrect port was selected then this allows a more streamlined resolution to that problem.
- Fixed crash when connecting to ECU via FTDI connection with hotplugging enabled.
