Happy 2nd Birthday UMF

Today it's now been 2 years since UMF first released.
Progress has been slower this second year largely due to UMF being in the process of being rewritten.
A rewrite has long been necessary to better provide support for new features, more reliability and stability as well as code cleaning.
The new UMF will feature a brand new UI, new config system, better mod packaging, better mod library and third party library support, improved encryption, and a lot more.
This means all existing mods will break, and will require them all to be updated to work.
When the new UMF is ready for testing, it will remain in beta for several months to give mods a chance to be updated, before UMF is released on the stable branch.
There is no set date or estimate for when this new UMF will be out, but you can follow some of the progress on our Discord.

New Release v0.53.0

A new version (v0.53.0) of UMF has now been released.
This release is both late and too early;
Late because I have had a lot on my plate and packed too many changes into one update.
Early because it contains some unfinished features such as the Mod Manager.
Due to the size and early release of this update it's likely to contain a few uncaught issues.

This update features;

• - Support for Unity Engine 2019


• - Support for Mod Packs (Website support to be added later)


• - Support for Universal Mods


• - Major improvements to the UMF Installer


• - Improved Mod Library/API support


• - Various Bug fixes and internal improvements.

See the Changelog for a full list of changes.

Happy Birthday UMF

Today it has been 1 year since the first release of UMF.
In that year UMF has been downloaded more than 73,000 times by more than 50,000 unique users, despite having just a few mods available for most of that time.
UMF has come a very long way in just a year, and still has so much more in store for it.
While there is no new release today, here are some of the things coming in the next few releases:

• - Fixes for MacOS


• - Easy Modpacks


• - Slime Rancher Mod API


• - A rewrite of the in-game GUI


• - More integration and improvements with the website

The documentation is also in the process of being moved to a better wiki software, due to nothing but problems with the current one.
It will replace the current wiki URL as soon as it is ready.
More official mods for more games are also coming, but anyone could start creating mods with a little bit of learning.
There are a lot of other big plans for UMF not mentioned here, but those will take a lot more time.

New Release v0.52.1

A new version (v0.52.1) of UMF has now been released.

New Website and New Release v0.52

A new version (v0.52) of UMF has now been released.
With this release we also bring a brand new website with mod hosting!
This is only a small beginning of big things to come.

The UMF update brings an all new Installer, a one-click mod installer, new tools for mod creators, and much more.
Due to the introduction of Harmony 2.0 all old mods will break with this release, but fear not, we have updated all of the official mods to go along with this release.
See the Changelog for a full list of changes.

The documentation has been moved over to the wiki and updated, and will continue to be built on over time.
You can find the new documentation here.
