TWiki-4.3.1 has a significant number of changes compared to previous TWiki-4.2.x and TWiki-4.3.x releases so it is not feasible to provide a download file with only the changed files. Instead we provide upgrade packages TWiki-4.3.1-upgrade.zip and TWiki-4.3.1-upgrade.tgz where the most common tailored files are omitted. Most people will be able to copy these files on top of a running TWiki-4.2.x or TWiki-4.3.x (always take a backup). If you upgrade from TWiki-4.2.x it is recommended to regenerate the lib/LocalSite.cfg by renaming it as a backup and re-running configure which will create a new LocalSite.cfg. You can use your backup to refer to your old settings.
Note that TWiki.TWikiPreferences will be overwritten by the upgrade package as it contains an important update. If you have changed TWiki.TWikiPreferences (which we advice not to do, instead copy the settings to Main.TWikiPreferences) make sure to save a copy before applying the upgrade.
The upgrades are cumulative, that is, the TWiki-4.3.1 upgrade includes the changes from TWiki-4.2.1 through TWiki-4.3.0. You do not need to apply one by one.
The TWikiReleaseNotes04x03 contains additional information for the upgrader.
Upgrading From TWiki-4.1.x
Significant changes has been made since TWiki-4.1.2 so upgrading cannot be done by applying a patch.
The upgrade can be done relatively easily by following the the procedure described on TWikiUpgradeGuide.
