Icon Differences from XTide 1

XTide 2 is a complete redesign of XTide 1. There are too many subtle improvements to list them all, but here are the not so subtle ones:

These are the non-obvious things you must know in order to migrate:

  1. The environment variable HFILE is no longer used to specify the harmonics file; instead, HFILE_PATH is used:
    export HFILE_PATH=/etc/harmonics:/etc/offsets.xml:/etc/harmonics.anchorage
    
    If HFILE_PATH is not set, XTide looks for the file "harmonics" in the default directory.
  2. XTide now has its own built-in icon. Remove any icon settings that you made in your window manager init files.
  3. You may no longer use anonymous units in harmonics files. The units must be one of the recognized alternatives. These are: feet, meters, knots, knots^2 (for hydraulic currents). If you are still using an ancient harmonics file that contains no units or "bogo-knots," then shame on you. It's high time that you upgraded.
