UPGRADE STEPS AS OF 10/12/2026:


Short version (TL;DR):

  ALWAYS replace all existing EXEs and DLLs with the new ones in the release.



Detailed version:

  This version of uMRC comes with an updated OpenDoors DLL library file:

  - ODoors63.dll

  Replace your old ODoors*.dll file with this one. Using any other DLL 
  file will cause uMRC to not work properly.

  If you're upgrading from v099 to v100 or later, note that the following DLL 
  library files have changed:


  Old DLL files no longer needed:

  - libcrypto-41.dll
  - libssl-43.dll

  New DLL files included with uMRC:

  - crypto-57.dll
  - ssl-60.dll


  Next, overwrite the contents of the "screen" subdirectory, since the contents
  of the help files may have changed.

  Don't forget the theme files in the "themes" subdirectory.

  Finally, obviously overwrite the old EXEs.

  Your old mrc.cfg and userdata files should continue to work just fine
  after upgrading.
