Three bug fix releases this weekend.
Version 1.4.9 fixes an ebook creation error that occurred if Amazon’s kindlegen software was not available on the host machine.
Version 1.4.10 makes the install process more seamless and less error-prone by automating a configuration step that previously needed to be carried out by hand.
Version 1.4.11 fixes a cosmetic error in the bibliography section, where book titles beginning with special characters such as the #hashtag were interpreted as markdown and therefore formatted incorrectly. Markdown characters at the beginning of the line are now removed.
To update an existing installation, simply do
git checkout master && git pull
