We have an instruction on how to translate OpenIV into your own language and we are calling for you to do so. You can find a changelog for this version on our bug-tracker here. General changes, improvements, and fixes in OpenIV 4.1 The main change in this release is the improved Hash Generator tool.
New features will come in future updates. This means that this release does not have long-awaited RDR 2 editing features. As a first step, we decided to release OpenIV 4.1 with the features that were already finished. The development of OpenIV was halted in the summer of 2021 due to team creative burnout.
Today we are happy to announce that OpenIV is back in development and release of OpenIV 4.1.
