1.1.3

Tiny bugfix for Debian.

1.1.2

It is now possible for the user to control whether highlighting is
combined in text mode.

Added a cache for page images. This makes it much quicker to flick back
and forth between pages. The cache size can be set by the user: the
bigger the cache the more pages that can be flicked through without
recalculating.

1.1.1

Replaced QVariant::toReal() with QVariant::toDouble() to avoid breaking
compatibility with Qt 4.4.

1.1.0

Added margin rules to indicate where changes are. (These can be turned
off by setting a rule width of 0.0.)

1.0.0

Implemented the sequence matcher algorithm for text mode matching.

0.6.0

Redid the user interface to use dock widgets.

0.5.0

First release.
