OpenIV refreshes download mirrors and rolls out installer update improvements

OpenIV, the core archive/editor utility used by many GTA modders, has refreshed its download mirrors and documentation and is rolling out improvements to its install/update system, and a mirror listing shows an update entry dated February 22, 2026. The project attached a changelog labeled "OpenIV 4.0.1" that includes an "Installation and updates improvements" section and a string "June 24th, 2020OpenIV 4.0.1" in the provided text.

The changelog begins the rollout of a new installer and updater, listing concrete first-step changes under "## Installation and updates improvements." Implemented items in this release include: "The setup package is now smaller." and "Download speed for updates from this version to the future version should be faster than previous." Those two lines are the only implemented update-system claims present in the changelog excerpt.

The announcement also lists planned features that maintainers say will follow later. The changelog explicitly states: "Small partial patches support. This will allows us update some files of OpenIV (like RDR 2 filenames databases or localization packs) without updating whole application." It also lists "Different update channels support. This will allows us to provide BETA versions before general release." The post closes that section with "Those improvements planned to arrive later this year."

The release notes include multiple bug fixes and functional changes for editors and modders. The changelog states: "We fixed an issue that prevented launching Grand Theft Auto V (Epic Games Store) from OpenIV." It also records: "We fixed an issue that caused OpenIV to crash when opening some models and textures in GTA V." A third fix reads: "We fixed an issue where OpenIV did not update the size of a nested archive if you deleted all files in it." Practical workflow changes are called out as well: "You can add names and strings to OpenIV databases by editing files in your Documents folder: Documents\OpenIV\[Game Name]\Strings\ Starting with this update OpenIV will automatically reload contents of these files if they were changed while running."

The changelog contains bilingual headers and framing text, including Russian lines such as "Установка и обновление" and "Сегодня мы рады сообщить о выпуске OpenIV 4.0.1, небольшого обновления направленного на улучшения поддержки игр и стабильности." The document also notes "## Локализация интерфейса" and advises users that "Вы можете найти список изменений для этой версии на нашем баг-трекере здесь."

The mirrors and documentation refresh appear to be live in at least one public mirror listing, which shows an update entry dated February 22, 2026; the provided mirror line is truncated in the available material and does not include a mirror hostname or URL linking that entry to a specific version. The changelog text and the February 22, 2026 mirror entry are both present in the supplied materials, but they are not explicitly connected by any additional metadata in those extracts.

Modders can expect a smaller setup package and faster update downloads immediately, with partial patches and BETA channels promised as later rollouts under the timeline quoted: "Those improvements planned to arrive later this year." For a full list of changes the changelog directs users: "You can find list of changes for this version on our bug-tracker here.
