 ### Fixes
 
+- Sandbox: pass configured `sandbox.docker.env` variables to sandbox containers at `docker create` time. (#15138) Thanks @stevebot-alive.
 - Onboarding/CLI: restore terminal state without resuming paused `stdin`, so onboarding exits cleanly after choosing Web UI and the installer returns instead of appearing stuck.
 - macOS Voice Wake: fix a crash in trigger trimming for CJK/Unicode transcripts by matching and slicing on original-string ranges instead of transformed-string indices. (#11052) Thanks @Flash-LHR.
 - Heartbeat: prevent scheduler silent-death races during runner reloads, preserve retry cooldown backoff under wake bursts, and prioritize user/action wake causes over interval/retry reasons when coalescing. (#15108) Thanks @joeykrug.
