Latest Version 5.12.2

Level of Importance: Highly Recommended
This release fixed a few bugs:
- Fixed an issue where CAN multi-frame message transmission would cause the device to lock up after 35 minutes of uptime
- Fixed handling of ATCRA, ATCF, and ATCM so their values are preserved when ATSP or ATTP are issued, matching ELM327 behavior
- Fixed rare issue where an overflow condition could reduce message delay times
- Fixed rare ISO 15765 flow-control frame transmission failure during concurrent multi-frame reception
- Fixed INTERNAL ERROR when receiving more multi-frame messages than specified
- Fixed ATCRA not restoring default filters when used without a parameter
- Fixed bug, STPX now properly sends 29-bit CAN messages when the AT/ST protocol is configured to 11-bit CAN
This release also added a few new features and a change:
- Added the Batched Commands feature, which supports sending multiple commands/requests in a single prompt
- Added the STBC command for enabling and disabling the Batched Commands feature
- Added the STBCOF command, which sets the output format for batched commands
- Added an optional parameter to STM and STMA commands to exit monitoring after reaching the specified message count
- Added the STITW command to set ISO protocol W timings
- STCSTM now also sets ISO 11898 inter-frame delay for segmented messages
