Comments

I cannot find the upgrade script to upgrade from 4.0.5 to 4.1.0. Am I looking in the wrong places?

-- AlexanderNicolovius - 17 Jan 2007

The upgrade procedure is found in the root of the distribution and it is a manual process. Experience has shown that it is in practical safer and better to upgrade manually because different installations have different local tailorings.

-- KennethLavrsen - 17 Jan 2007

Is the upgrade from 4.0.5 to 4.1.0 a full installation? Or is there a patch upgrade path that I'm missing? I looked at INSTALL.html and TWikiUpgradeGuide.html, but neither seemed appropriate.

-- JoshuaTharp - 26 Jan 2007

There is no patch package to upgrade from 4.0 to 4.1, please follow the TWikiUpgradeGuide.

-- PeterThoeny - 26 Jan 2007

The configure tool in TWiki 4.1.0 currently does not work with Perl 5.6.5 (and maybe other older versions). If you have Perl 5.6.5 you can either configure it manually (quite difficult) or use TWiki 4.0.5 for now.

In Cairo we have internal links in the form [[foo.bar.de]] which points to the topic Foobarde in the same web. After upgrade to 4.1 this is a broken link cause it points now to the Topic De in subweb BAR under web FOO. Is this a bug or a feature?

-- OlafBerg - 30 Jan 2007

That is a feature and a somewhat unfortunate spec change for existing users.

-- PeterThoeny - 30 Jan 2007

You should use the support web for these questions. It is a feature called subwebs.

-- KennethLavrsen - 30 Jan 2007

There seems to be a problem with the 4.1.0 distribution files. Both the ZIP and TGZ versions are missing files from the TWikiDocGraphics library. These files are referenced in the TWikiDocGraphics topic, but are missing from the attachment directory: list deleted -- TW

-- BryanThale - 04 Feb 2007

This has been reported as Bugs:Item3500 and will be corrected in 4.1.1.

-- ThomasWeigert - 04 Feb 2007

I've been dealing with software since the RSTS-E days. This one's so unfriendly, I deleted it. Get you head out Peter.
