v1.0.66

# EXO v1.0.66 Release Notes

This is a stability release that fixes a regression with RDMA / Tensor Parallelism where models were getting stuck in `LOADING` state. It also fixes a download edge case with GLM 4.7 Flash and nodes getting stuck in `UNKNOWN` state / zombie states after periods of inactivity.

All models have been confirmed working with RDMA / Tensor Parallel on various configurations (including Mac Minis, MacBooks and Mac Studios). Thank you to users who reported bugs to help us resolve these issues - it helps a lot!

## Bug Fixes

- Use EXO shard instead of upstream shard for all models, loading models layer-by-layer, fixing models getting stuck in `LOADING` state e.g.`GLM-4.7-Flash-4bit`, `gpt-oss-120b-MXFP4-Q8` and `Qwen3-Coder-480B-A35B-Instruct-8bit`. Also fixes memory not being released when an instance is deleted. ([#1291](https://github.com/exo-explore/exo/pull/1291))
- Fix downloads getting stuck when model files change in Huggingface repo e.g. `GLM-4.7-Flash-4bit` which was updated upstream on Jan 25 ([#1290](https://github.com/exo-explore/exo/pull/1290))
- Always publish info gatherer events, preventing nodes getting stuck in `UNKNOWN` state / zombie states after a period of inactivity ([#1283](https://github.com/exo-explore/exo/pull/1283))
- Fix tool calls with empty text content ([#1292](https://github.com/exo-explore/exo/pull/1292))
