Note: The Gentoo Portage Managers have updated TikiWiki packages:

• http://packages.gentoo.org/ebuilds/?tikiwiki-1.8.6
• http://packages.gentoo.org/ebuilds/?tikiwiki-1.9.1

For a list of pending bugs on gentoo bugzilla query:

• ALL Tikiwiki

TikiWiki 1.7.x is not secure and is no longer being maintained. Admins should adopt 1.8.6. (Old policy: Receives only bug fixes and security fixes.We do not add any new feature to it, nor backport any new feature.)

TikiWiki 1.8.6 should be used in production environments.
TikiWiki 1.9 is a developer and tester version, it is stable enough to run but things break from time to time. New features go there. (Old policy: We are in feature freeze and code clean up.)

TikiWiki 1.10 is a developer version, major new features go there.
