What's in this Update?
While I've made changes in every chapter, below is a list of some of the most interesting updates:

- Switched to the
langdetectpackage for language detection.
- Upgraded Ubuntu to 20.04 in Linux deployment chapter.
- Addressed issues with Heroku's Postgres database and SQLAlchemy 1.4.
- Solved issues with recent releases of the pymysql package requiring the

There is one aspect of the tutorial that is still in need of an update: the use of the Flask-Bootstrap extension. Unfortunately this extension has not been updated in a long time, and it continues to require version 3 of the Bootstrap CSS framework, which is now two major releases old. While there are a few forks of Flask-Bootstrap that implemented support for Bootstrap 4, there are currently none that I know of that support Bootstrap 5. Out of the Bootstrap 4 forks, most are already unmaintained, or else they don't have a clear path to Bootstrap 5. Given that there are no worthy successors to Flask-Bootstrap, I have decided to continue using this old version, which continues to work well, with the caveat that it keeps the user interface stuck on Bootstrap 3. I will continue to monitor this and update the Bootstrap chapter when a good alternative to Flask-Bootstrap appears.
How to Get this Update
The update to the tutorial is available right now on this blog. This continues to be freely available to everyone.
If you have purchased the paid version from my Courses page, first of all thank you so much for your support, and second, you can find the updated ebook downloads and text of the tutorial in your course page. Note that most of the updates are minor in nature, so at this time I have not made updates to the video material.
