Patchmanager is a tool for transparently modifying installed files by the patch utility and for managing the special patch files ("Patches") for doing so. Since version 3.0, Patchmanager does not modify original files on mass storage, it merely alters their content when they are loaded into RAM to be executed.
Note that Patchmanager does not install an application icon on the launcher, but creates a new entry in SailfishOS' Settings app.
To install a recent Patchmanager the SailfishOS:Chum community repository can be used, which is easily accessed with the SailfishOS:Chum GUI application, which in turn can be installed via the SailfishOS:Chum GUI Installer. Alternatively Patchmanager can be installed from its OpenRepos repository using Storeman, which can be installed via the Storeman Installer. While these two sources can also be used to manually download and install Patchmanager, you may alternatively obtain Patchmanager RPMs from its releases page at GitHub. Note that the Patchmanager's OpenRepos repository and GitHub releases page also offer the final releases of Patchmanager 3.0 for SailfishOS < 3.4.0 and Patchmanager 2.3.3 for SailfishOS < 2.2.x.
Modern Patches for Patchmanager 3 are provided via the Web Catalog, while older Patches were provided as RPMs at OpenRepos and some of them are still maintained. Mind that many Patches were first released at OpenRepos but later migrated to the Web Catalog: For these you will find outdated RPMs, hence always search in the Web Catalog first.
