After doing some checking and research, I’ve noticed that Haiku currently runs Discourse 2.5 and Trac 1.4.
The latest version of Discourse is 2.6 which was released today. The release notes are here:

The latest version of Trac is 1.4.2 which was released in June. Release notes are here:

Discourse 2.6 has many improvements and bug fixes, and Trac 1.4.2 is a maintenance release which focuses on bug fixes and stability improvements, so it might be a good idea to install these updates.
Thanks!
