Today we are happy to announce that OpenIV is back in development and release of OpenIV 4.1.

Pause in development

The development of OpenIV was halted in the summer of 2021 due to team creative burnout. We are now trying to resume development. As a first step, we decided to release OpenIV 4.1 with the features that were already finished. This means that this release does not have long-awaited RDR 2 editing features. New features will come in future updates.

Improved Hash Generator

The main change in this release is the improved Hash Generator tool. Hash Generator how has options to:

  • Change Hash algorithm: Default, Case Sensitive, AWC
  • Change Output format: Hex, Unsigned int, Signed int
  • Generate on typing

General changes, improvements, and fixes in OpenIV 4.1

  • You can now create a sequence of folders at once (e.g. x64\data\lang);
  • We added Rename feature into Organize Favorites window;
  • More file types are now associated with Text Editor;
  • Fixed an issue where OpenIV generated incorrect XML exported by the “Export to XML” feature.

You can find a changelog for this version on our bug-tracker here.

UI Localization

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 the localization guide on GitHub. As for existing localizations, here is the list of differences between 4.0 and 4.1.
