MJOLNIR Launcher changelog

Installs the runtime, manages your mods, and launches Halo Campaign Evolved.

29 releases · latest v0.6.0 · Documentation

v0.6.0

Point the launcher at your game

If MJOLNIR cannot find Halo Campaign Evolved, you can now choose the folder yourself instead of being stuck on the Game Not Found screen.

v0.5.3

Verifies author-signed mod archives

The launcher refuses to install a community mod whose author signature does not verify, pins each mod's signing key, and warns you when a key changes or is revoked.

v0.5.2

Setup installs the mods a new install needs

First-time setup no longer finishes with a modding framework and nothing to run in it, and the rest of the signed mods are now listed in My Mods with an Install button.

v0.5.1

The signed badge tells the truth, and updates install quietly

Mods installed by an earlier launcher now verify as signed instead of reading unverified forever, and automatic updates stop interrupting you with an installer prompt.

v0.5.0

The signed runtime replaces the modpack

The launcher installs a signed runtime bundle instead of the old modpack, refuses one whose signature does not verify, and stops overwriting your settings.

v0.4.1

Automatic updates work for the first time

Fixes automatic updates, which had never worked in any released build: the launcher was silently blocked from checking, and reported the block as "up to date".

v0.4.0

The hub release: browse, rate and update mods in the launcher

The launcher becomes a full hub client: mod pages, ratings and comments built in, one Updates screen for everything, and sign-in by pairing.

v0.3.3

A Tools tab, and the Tag Editor

Adds a Tools tab that installs and updates companion apps on demand, starting with the new MJOLNIR Tag Editor for browsing and editing the game's tags and textures.

v0.3.2

Security: replaces the update signing key

Replaces the key that automatic updates are verified against, after the previous private key was found committed to the public repository.

v0.3.1

Update notifications you cannot miss

Fixes automatic updates, which could not verify a download and so never installed one, and adds an update badge that persists after you dismiss the banner.

v0.3.0

Install, verify and toggle the mod framework from the launcher

The launcher now installs the UE4SS modding framework for you, verifies every file it wrote, and supports Game Pass copies of Halo Campaign Evolved as well as Steam.

v0.2.6

The Windows installer builds again

Fixes the Windows installer, which had stopped building since the branded artwork was added in 0.1.3, leaving several releases without one.

Release pipeline only

A version bump published to exercise the release pipeline. Nothing in the launcher itself changed since 0.1.1.

v0.1.1

Automatic updates

The launcher can now check for new versions and install them itself, instead of asking you to download a new installer by hand.
