Hotfix to fix several bugs with the 3.9.2 beta, including issues with the melter.

For a full changelog, see https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.9.2.37

For all 3.9.2 changes, see https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.9.2.34

First beta for 1.20.1. This means the API should be stable enough for addons, however game content may still get changes and rebalances, so keep an eye out on future updates if you are a modpack dev. There may still be bugs.

Full changelog: https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.9.2.34

Hotfix to fix a crash with projectiles on NeoForge. Requires Mantle 1.11.36 or later.

Full changelog: https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.9.1.19

Bug fix and small feature update. Requires Mantle 1.11.36.

Full changelog: https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.9.1.17

Will likely be the last release for 1.19.2 unless major bugs are discovered. Development is moved onto focus on 1.20 now.

Full changelog: https://github.com/SlimeKnights/TinkersConstruct/releases/v3.8.5.58

Update to 1.20.1. This build is an alpha, meaning things might be broken and APIs may change. Don't add to a modpack unless you plan to continue to support the modpack for the next several months.

If you are an addon author, know that the API is not yet stable so you may have to make changes when the next release is made. Otherwise, if you wait for a Beta release the API will be stable. See GitHub for what to expect to change in future 1.20 builds.

For a full changelog, see https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.9.0.6

This will most likely be the last release for 1.18.2 barring any significant bugs discovered. It contains a ton of bug fixes and minor features backported from the 1.19.2 branch.

For a full changelog, see https://github.com/SlimeKnights/TinkersConstruct/releases/tag/3.7.2.167

Contains many bug fixes along with smaller new features. Should be a much more stable release than the previous 1.19.2 build.

For a full changelog, see https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.8.4.50

First Beta release for 1.19.2. API should not break after this point, if it does feel free to open a bug report. This means it is fully safe for addons to update.

There may still be balance changes in future builds, want to finalize a couple things before marking this as release.

Full changelog: https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.8.3.39

Hopefully should be the last major API changes. Marking this as an alpha mostly as it needs more testing, but addons should have a lot less risk of breaking when porting to the API from this alpha.

Changelog: https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.8.2.32

General bug fix and improvement update. Requires Mantle 1.10.24.

Full changelog at https://github.com/SlimeKnights/TinkersConstruct/releases/tag/v3.8.1.16

Obligatory Alpha Warning

This build is an alpha. Alpha means things might break. Specific points:

• We will do our best to prevent worlds from breaking, but make backups of worlds just in case.
• Do not include this build in a modpack unless you plan to stick around on 1.19.2 long enough for us to get a stable release out. We don't want to constantly get reports of issues we have long since fixed because a modpack did not make a stable experience.
• If you are an addon author, know we make no API stability guarantees until we make a beta. Check out the Roadmap for specifics on what we plan to change. Feel free to ask on our discord if you have any questions on updating.
