  • Much simpler install and configuration
  • Integrated session support
  • Webserver-independent login/logout
  • Security sandbox blocks all possible routes for remote command execution on the server
  • New editing model with conflict resolution allows freer collaboration, without fear of overwriting other people's changes

TWiki Patch Release 4.0.2

TWiki Release 4.0.2 supercedes TWiki Release 4.0.1, and addresses many important bugs and only few minor enhancements. For full details see the patch log below.

If you have TWiki Release 4.0.1 installed, you can download and install just the newer files contained in changed files.
Pay attention to not overwriting important pages which have been modified locally, like Main.TWikiAdminGroup or Main.TWikiUsers for instance. Also, note that users may have visualization problems on certain pages, due to CSS changes, which can be solved by force-reloading the pages.-- OlivierBerger - 02 Apr 2006

List of Changed & Removed Files


Is there going to be a patch file so it is possibly to simply patch an existing install from 4.0.1 to 4.0.2?

-- JeffersonCowart - 03 Apr 2006

FYI, it seems a patch had been provided at some time (r1.15 of current page), although I'm not sure how complete it was compared to tarbals provided now. Maybe history of this topic can provide you with these details ?

-- OlivierBerger - 03 Apr 2006

we are testing a patch file now

-- WillNorris - 03 Apr 2006

This is my first upgrade to my first TWiki installation, and guess what? I've modified a couple of files in the TWiki web which started me thinking about what to do. I've read some of the discussion about this from the last couple of years - is there any appetite for a new discussion about RCS and ways of handling local changes, or have the scars from the earlier ones not healed yet?

-- PeterKeller - 04 Apr 2006

Could you provide either a zipped package or a patch file for an upgrade path from 4.0.0 to 4.0.2? I had issues with the patch file to go to 4.0.1 so I skipped that, waiting for 4.0.2.

-- AlexTirdil - 04 Apr 2006

I would also very much appreciate a patch - from 4.0.1 to 4.0.2 in my case...

-- DirkSchlossmacher - 05 Apr 2006

Is there an easy way to just install the files changed from 4.0.1 tot 4.0.2? The changes seem significant, but i'm hesitant to reinstall everything. Detailed instructions for working from a unix shell would be much appreciated. OK, I've installed the supplied zip with changes and the fix, which work. Although i do not know why all these support files are redistributed for such a minor release... makes it hard not to deleted changed content. (e.g.: i kept my own TWikiPreferences and lib/TWiki.cfg - should I have installed the one in the changes.zip?)

-- JosMaccabiani - 08 Apr 2006

UpgradingTWiki04x00PatchReleases is the latest document done in the efforts to assist in upgrading to Dakar. It is a bit more cookbook-like than previous documentation, I believe it will be helpful to have handy in this case where changed content is an issue.

-- SteffenPoulsen - 10 Apr 2006

Yes! this is perfect, thank you very much.

-- JosMaccabiani - 10 Apr 2006

Is a patch from 4.0.1 to 4.0.2 still in the pipeline?

-- JamesAnderson - 24 Apr 2006

Same question from my side. I'm still on buggy 4.0.1 and hesitating to go the manual upgrade way... Thanks for any hints and ... the patch!

-- DirkSchlossmacher - 25 Apr 2006

We have trouble attaching files to a topic with 4.0.2. After the request is sent by the browser the it takes ages until it gets a response. Any ideas? Thanks. RST

-- ReneStoeckel - 28 Apr 2006

Please ask support questions in the Support web. (To help find out why, provide as much detail as possible.)

-- PeterThoeny - 29 Apr 2006

Refactored out TWikiR04x00x02EmailFix and added note to "read also the known issues topic."

-- PeterThoeny - 01 May 2006

Note : If rou're running version 4.0.2, %WIKIVERSION% should be "Fri, 31 Mar 2006 build 9626"

-- OlivierBerger - 13 Jun 2006

ALERT! Note: Please use Bugs:WebHome to report bugs
