Changelog

d391c3a 1.3.50

Fixes sparse padding of diffs for wide tables, see #126

• Updates optional sqlite3 dependency from 3 to 4 (#122)
• Exposes a flag for controlling number of context columns (#121)

Bugfix: don't swallow a final cr/lf in a cell when rendering to CSV, see #117

python fix: avoid use of reserved keyword async, a problem in python 3.7, see #115.
