These outages will also affect open textbooks in the B.C. Open Textbook Collection that are hosted in BCcampus' internal instance of Pressbooks (opentextbc.ca). We will be updating Pressbooks tomorrow . We apologize for the late notice, but there is a security issue that needs to be addressed as soon as possible. But there is good news! This surprise update means that we get to bring you a lot of great new features just before the holidays. UPGRADE NOTICE On December 21, 2018 , from TIME to TIME, Pressbooks (pressbooks.bccampus.ca) will be upgraded to version 5.6.3. Your account will be unavailable during this time.

See the Pressbooks User Guide for more information: Glossaries . * Expanded webbook table of contents: The table of contents that appears on the webbook home page is now expanded by default so all chapters that are contained within parts will be displayed. * Custom "Part" and "Chapter" labels: You can now customize "part" and "chapter" labels in exports.
