I am happy to announce the release of Nikola version 5.3. It includes some minor features and a good amount of bugfixing. Upgrading to it should not cause you any trouble, as far as I know.
Here's the changelog:

New Brazilian portuguese translation.
New planetoid experimental extra_plugin
Make really sure we import the right conf.py
Make SLUG_TAG_PATH a config dep for most pages
Removed meta title tag for better HTML validation
Removed #999 background from footnote backlink.
Made footnote references be superscripted.
Centered figure's image and caption.
Removed outset border from admonitions.
Use default theme as last resource for messages/translations
DATE_FORMAT option was being ignored
Remove trailing "" on windows gallery links (Issue #298)
Inconsistent breadcrumbs in gallery pages (Issue #303)
Use source files as bundle dependencies instead of outputs (Issue #294)
