This release adds an automatic mod updater, you can run it from the top menu bar.
For now the mod updater can only update Sideloader Modpacks. Only the changed files are downloaded to save bandwidth, and outdated/replaced files are automatically removed.
Some version of the Sideloader Modpack that you want to update has to be already installed, for now there is no way to add a modpack from 0. You can get the full modpacks from the mega folder or by installing the HF Patch. The modpacks have to be in their default directories to be detected so don't rename them (shown in the screenshot below).
Loose files in your mods folder will NOT be checked, if you dropped any mods in there you will have to manually remove them if necessary.
Big thanks to DeathWeasel for maintaining the Sideloader Modpack and assistance with creating this feature! Check his patreon for information about Sideloader Modpack updates, and consider showing him some support!
In the future I will add updating plugins to the mix. Long term plan is to have this updater replace HF Patch (KKManager will be able to do everything that the patch does, while downloading only the files that are necessary).
