The change history for osgb

0.0.x - Paul's old versions

1.0.0

• New super-accurate conversion routines based on OSTN15
• Preserves legacy interface

1.1.0

• Documentation at https://grid-banger.readthedocs.io/en/latest/index.html
• Moved all functions from mapping module into gridder
• Fixed issue with array.array methods for Python2 v Python3

1.2.0

• Changed rounding behaviour for osgb.convert.grid_to_ll

  This is a mildly breaking change, in that the default outputs will have fewer decimal places, but it does not mean any loss of accuracy. If your GR is in whole metres, your lat/lon will be rounded to 6 decimal places which is about 10cm of accuracy. A new "rounding" keyword arg allows you to have more places if you really want them.

• Allow tuple argument to sheet_keys

• Improved error handling in parse_grid

• Added a script to make a GeoJSON file of each series of map outlines

• Added a zero-points script to show "meetings of Myriads"

• Added flag to bngl.py to show lat/lon in degrees-minutes-seconds notation

• Improved test coverage

2.0.0 (future plans)

• The next major release will drop support for Python2
