• #134: Fixed a few bugs that caused the installer to fail in weird ways during a fresh install (i.e. for Docker users).
• #136: If you don't specify a subheader in the blog config, nothing will be displayed.
• #139: If an author's biography is empty, the "About the Author" section will not be displayed. In a future version, we may change this behavior to be dependent on the status of a checkbox rather than the non-emptiness of the biography field.
• #142: Hide "Uncategorized" from the right menu if there are no blog posts without a category.
• #143: Fixed issues with date/time handling that broke post editing.
• #144: Fixed the regular expression in the required attribute that caused browsers to prevent form submission.
• #145: The "default format" is now respected by the forms that support different input formats.
• #146: Created a button to purge the caches.
• Hid the link to view blog post history, as that feature was overlooked. We'll implement it in version 1.4.0.
• Some image types can be viewed directly instead of always forcing a download. The enforcement logic is a whitelist (that gadgets can extend).

Also, this runs an autorun script that was overlooked in preparing the v1.3.0 update. If you had broken symlinks for the new Motifs, this will fix it automatically.
