TikiWiki 2.0 (previously known as 1.10) was released in August 2008
Table of contents
TikiWiki is truly a community success. Over 80 people contributed 6894 commits (code changes) to the source code of version 2.0 and so many more to testing, documentation, bug reporting, etc.
Nelson Ko acted as release manager and Louis-Philippe Huberdeau handled the packaging.
There are tons of enhancements. Really! You can read the changelog to see the 6894 commits (code changes)
Or you can read the general overview of new features:
As with any major release, if you have a production site, test the upgrade to the new version on a test environment first.
Remember, backup your database before running any scripts!
The tiki_1.8to1.9.sql will bring your database up to the latest version of the 1.9 series and then the tiki_1.9to2.0.sql script will bring you from the 1.9 database to the 2.0 database schema.
Tiki 2.0 needs a memory_limit setting fixed to, at least, 32M. With less than 32M, you will have some white screens when browsing some functions.
Category permissions have changed significantly in 1.10. Most notably in order to edit content in categories a user needs tiki_p_edit_categorized. This permission needs to be manually assigned to groups in Category Admin and Groups Management individually.
A database administrator can consider using the information in Category Perms MySQL queries to facilitate an upgrade. However note that these queries give users that previously had the ability to view content in categories to edit the content as well. This may not be what you intend. The safe way is to configure permissions manually.
Also if you had upgraded using the Tiki installer then users that previously had the ability to view content that is categorized will continue to have them. If you however upgraded by manually running 1.9to2.0.sql there are some queries here that you may have to run Category Perms MySQL queries.
- Descriptions no longer accept html but can be wiki parsed
- Field type: user selector options have changed. You need to reset them according to the new doc. (or maybe just a bug)
- If you customized your templates you should remake them.
- Even with bundled themes you will notice some visual changes
- You may want to change "Preference syntax" in tiki-admin.php?page=general to 1.9.x to use old variable names or you can convert your templates to use the new variable names using this script
- Joshua Morin reported several issues
- Jesús Olmos at Internet Security Auditors reported a leak which could be used to disclose path and PHP configuration.
- Special thanks to Philippe Gamache & Damien Seguy for their advice
Many users do not realize that these features that provide the ability to edit files that are part of the TikiWiki installation from the web can be a security risk if permission to use these features are given to non-admin users, and that editing of local files on the server is inherently risky. Pending further improvements in version 2.1 and 3.0, changes in this version 2.0 have added input sanitization for many strings that are deemed risky — making it likely that certain content cannot be entered through these features. The workaround is to edit the files on the server directly.
