[sglang] Tracking sglang compatibility in slime

Nobody has claimed this yet.

One of the key design goals of slime is to stay compatible with the latest releases of sglang. However, to support certain reinforcement learning (RL) features, we occasionally introduce minor modifications to sglang itself.

This issue serves as a centralized place to track relevant pull requests—both ongoing and merged—that affect or are affected by slime. It aims to facilitate collaboration and maintain alignment between the slime and sglang communities.

~~Ultimately, our goal is to eliminate the need for maintaining a separate sglang.patch file by upstreaming necessary changes directly into sglang.~~

As of sglang 0.4.9, the core features from slime have been merged into sglang. The remaining pull requests are primarily enhancements to sglang itself.

We’ll keep this list updated as development progresses.
