Version 3.6.19

• Corrections to function normalizeStr to replace some missing characters.
• Extended waypoint coordinate parser for all ARINC 424 Code Convention full degree waypoint
  formats.
• Added push request #16 of @flpduarte. Fixed bug in which Little Navmap would only read and
  display a single transition from addon (Community) SIDs and STARs, despite these procedures
  actually having more than one transition. This happens when using the latest MSFS SDK (SU9 or later).
• Now saving invalid and null parking names from MSFS with indicator NONE into the database to
  allow handling in flight plans.
• Now skipping empty X-Plane apt.dat files to avoid program freezing in an empty loop for
  malformed files.
• Fixed issue where airport frequencies were written as 0 instead of null for MSFS resulting in
  wrong search results.
• Database minor version updated to 21.
• Moved version number to variable in file atools.pro instead of coding into sources.
• Now writing files version.txt and revision.txt files into deployment folder allowing
  deployment scripts to automatically name archives.
• Improvements to Flightgear XML flightplan files import and export. Thanks to @colingeniet at
  Github for the fixes.
• Now decreasing connection rate for long running sessions using autoconnect to avoid loss of
  internal SimConnect handles. After 30 minutes, an attempt is made to connect every 30 seconds, and
  after one hour, every minute. Workaround for #891 which is most likely a SimConnect issue.
