Full Changelog: https://github.com/lambda-client/lambda/compare/0.0.1+1.21.5...0.0.2+1.21.5

We are incredibly proud to announce the release of the all-new Lambda Client, a free, open-source utility mod completely rewritten from the ground up for Minecraft 1.21.5.

This is not just an update; it is a new beginning. After over two years of development, we have rebuilt the client to focus on advanced automation, unmatched performance, and complex task execution with minimal micromanagement.

✨ Key Features & Changes

• Automation Engine: Features a full build engine with Litematica integration, conflict-free orchestration, and complex block state handling (rotations, attachments, etc.).
• New GUI: A sophisticated interface built on Dear ImGui offering fine-grained control over 1000+ settings.
• Elytra Boost: Now capable of speeds up to 200 km/h.

⚠️ Important Notices

1. 2B2T / Grim Anticheat: 2B2T has changed their Grim config as of today. While Lambda is “Anticheat Ready”, some features may require a rework or exhibit instability due to this sudden server-side change.
2. Legacy Client: The previous version of the client has been renamed to Lambda Legacy. It has been archived and moved to: https://github.com/lambda-client/lambda-legacy. Old addons are not compatible with the new Lambda.
3. Alpha Status: This is an Alpha release. While highly capable, please expect bugs and incomplete features as we progress toward Beta.
