I have just updated the plugin to version 1.5.0. This is a mix of change by myself and @kiwidude. The list of changes are:
- New: Add Reduce header sizes option to replace h1,h2,h3 tags with h4 in comments (off by default). Done by @kiwidude.
- Fix: Titles/authors with apostrophes can result in not finding search matches. Done by @kiwidude.
- New: Get the publishing date from the oldest editions. Can be configured on or off.
- Change: Fix layout of configuration.
- Change: Code cleanup.
Calibre should announce the update in the next hour or so. If there are any issues with the plugin, please report them here.
