ChanSort Change Log
===================
2023-01-06
- added support for numerous .DBM file formats used by DVB-C and DVB-S receivers based on
MStar chips. Known brands to use this format include Xoro, TechniSat, Strong, Comag and
many more. (If your file isn't recoginezed, please send it to me to add support for it)
2023-01-04
- TCL/Thomson: improved file detection (.tar file or directory containing DtvData.db,
satellite.db, cloneCRC.bin)
