 ## CHANGELOG
 
+### 2025-12-14
+
+Converted to multi-stage Docker build with improved build times and reduced final image size. The builder stage is now separate from the runtime stage, excluding unnecessary build tools from the final image.
+
+Added timing statistics to `build-and-copy.sh` to track Docker build and image copy durations, displaying a summary at the end.
+
+Triton is now being built from the source, alongside with its companion triton_kernels package. The Triton version is set to v3.5.1 by default, but it can be changed by using `--triton-sha` parameter.
+
+Added new flags to `build-and-copy.sh`:
+- `--triton-sha <sha>`: Specify Triton commit SHA (defaults to v3.5.1 currently)
+- `--no-build`: Skip building and only copy existing image (requires `--copy-to-host`)

 ### 2025-12-11 update
 
 PR for MiniMax-M2 has been merged into main, so removed the temporary patch from Dockerfile.
