+Version 1.13.0  (May 2021)
+
+This release supports Python 2.7, 3.6, and 3.7.
+It is the last release planned to support Python 2.
+
+Upgrade Instructions
+
+  To install updated dependencies, run:
+    pip install -r requirements.txt --no-deps --upgrade --upgrade-strategy=only-if-needed
+  Run `./rebuild-all.bash` to get new ForgeFeedback app available
+
+  If switching from Python 2 to Python 3, we recommend upgrading to Allura 1.13.0 first
+  and then switch Python versions as a separate step.  When switching Python versions, you
+  will need to make a completely new python virtual environment using Python 3, and run
+  `pip install ...` in it, and then use it to run Allura.
+
+  When running on Python 3, newer versions of Pygments and Pillow can be installed which
+  include security fixes within those packages.  The versions specified in requirements.txt
+  are older versions so that Python 2 can still be supported.
+
+  If you have customizations or extensions for Allura, you will need to port that code to
+  Python 3.
+
+.ini file changes:
+  If you have customized development.ini or docker-dev.ini for your own site, you will
+  need to remove all the stats references after the "Logging configuration" section.
+  Remove it from 2 `keys =` lists, and 1 `handlers =` list, and the whole [handler_stats]
+  subsection.
+
+  All `%` will need to be escaped as `%%`, for example in bulk_export_filename.
+  `%` in logging configurations at the bottom of the file is ok.
+
+  For python 3, comments on the same line like `foo = 123; comments` are no longer
+  allowed.  For example, `override_root = task` needs to be its own line only.
+
+  New configuration options are available.  If you have an existing .ini file, defaults
+  will be used automatically, or you can set your own values for: phone.attempts_limit,
+  scm.view.max_file_bytes, and scm.download.max_file_bytes
