A new maintenance release for ReefMaster 2 is available. To update, click the Check For Updates on the startup window or in the FILE menu.

Changes include:

• Sidescan channel now imported correctly when depths are missing in the original SL2 or SL3 sonar log file. Note that the ReefMaster generated .IDX file will need to be deleted manually to force the re-importing of any previously imported affected files. The .IDX will be in the same disk location and have the same name as the original sonar log file, with the addition of the .IDX extension.
• Added sentence selection window during NMEA log file import to avoid the problem of importing GLL and/or GGA messages with no date information (prefer RMC instead, if available).
• USR version 4 and 5 waypoint and trail support (import only).
• Fixed issue of truncated shaded relief map in maps with very large depth ranges.
• Fixed triangulation error that could occasionally result in some small map anomolies.
• Fixed issues with sidescan mosaic ordering during export.
• Fixed AT5 raster type issue producing raster maps with wrong layer type on some recent Lowrance units.
• Fixed error when opening MBTiles files from some third party providers.

Thanks for your continued support of ReefMaster

A further update, 2.1.50, is now available which fixes an error introduced with the last update (apologies), which could cause an infinite loop during the map generation in certain situations.

A further bug, crashing when using the same fixed-depth palette for both tracks and map layers, has also been fixed.

don't know if is the 2.1.50 release or some windows10 update but at moment I see Reefmaster opening the Workspaces faster than before

Opening projects could be quite a bit faster if you have big and/or self-intersecting shorelines. Opening workspaces themselves shouldn't really be affected.

Thank you Matt
