# Changelog

Notable changes to RTX Remix for Minecraft, newest first. Changes that a
player, a map author, or a contributor would notice go here; internal
refactoring does not.

The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and the project uses [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
The version in a release is the `mod_version` in `gradle.properties`, and it is
also part of every mod file name.

## Unreleased

## 0.1.0 - 2026-10-23

The first public release, a beta.

### Added

- Path-traced rendering of Minecraft Java Edition 1.21.1 through RTX Remix:
  terrain, entities and block entities, particles, the sky, and clouds, with
  baseline LabPBR textures built into the mod JAR through Fabric's `fabric` pack.
- Lighting that follows the game: time of day, weather, being underwater, and
  per-dimension skies, with the End's constant dark dome and a black sky with
  no ambient where a dimension has none. Map authors can give zones and biomes
  their own looks through gameplay-driven conf profiles installed beside the
  mod, with an authoring guide.
- Block lights from resource-pack rules, a Light Reach setting and an Auto
  light cull distance, flames and lights on hand-held items, and the `G` key
  to put out and relight what the local player holds.
- The Copper Beacon, a placeable and craftable directional lamp: dye and
  saturation, intensity, cone angle, redstone control, and static, rotating,
  oscillating, or patrolling motion that every player sees the same way.
- An RTX Remix settings screen in Options, a button into Remix's own Graphics
  Settings, the `/rtx` command tree, `F8` to toggle path tracing, and
  session-only quality presets through `/rtx preset <name>` or
  `-Drtxremix.preset=<name>`.
- Camera paths: record a flythrough by walking it and replay it on wall-clock
  time or one fixed step per frame. Still shots keep a pose together with its
  time of day, weather, path-tracing state, and cloud style.
- Procedural clouds, selectable in place of vanilla's.
- Steadier frames at high render distance: paced chunk delivery and unloads
  in single-player, a hold behind the loading screen after joining a world,
  and allocation-free hot paths that keep garbage collection out of the frame.
- A self-contained mod JAR that any Fabric launcher can install on its own,
  and a Windows installer for Prism Launcher and the Microsoft launcher that
  sets up Java, Fabric, the mod, and tuned JVM arguments, and repairs,
  upgrades, uninstalls, or exports an install.
- Developer tools under `tools/` through the `rtx` CLI: launching, benchmarks
  on the pinned demo world, built by [BlockWorks](https://www.blockworks.uk/),
  and the LabPBR art pack, created by an art team at NVIDIA, or on locally
  staged fixtures, JFR and Tracy profiling, and the contributor checks.
- Developer tools launch Minecraft through a Prism Launcher data folder for
  each checkout, signed in to a Microsoft account that owns Minecraft: Java
  Edition. `tools\rtx.bat prism signin` signs a checkout in, and
  `launch.jvmArgs` carries developer JVM options.
