v1.7.0 (2014-10-03)
- Save timestamps in POSIX time instead of a user-specific string format; the
format setting is now only used for displaying absolute timestamps in the
panel (see #28) - Remove doubled information in history file, namely 'action' key (#30)
- Fix a bug where quickly browsing through the reopen panel would cause some
views to get mistaken for real views and added to the history (#31) - Fix exception when timestamp could not be parsed (#28)
