All the new versions come with a number of bug fixes and improvements. You may see the changelogs for any individual package or library in the list below if you want to have all the details.
How to use the new versions for testing BEFORE the update
Users are strongly encouraged to test their software applications and data processing chain with the new versions of the various software packages before the date of the change to the default versions.
The new versions of the software packages can be selected by using the oct21 tag in modules. For example:
