 - Agent: deliver final replies for non-streaming models when block chunking is enabled. Thank you @mneves75 for PR #369!
 - Agent: trim bootstrap context injections and keep group guidance concise (emoji reactions allowed). Thanks @tobiasbischoff for PR #370.
 - Agent: return a friendly context overflow response (413/request_too_large). Thanks @alejandroOPI for PR #395.
+- Agent: auto-enable Z.AI GLM-4.x thinking params (preserved for 4.7, interleaved for 4.5/4.6) unless disabled. Thanks @mneves75 for PR #443.
 - Sub-agents: allow `sessions_spawn` model overrides and error on invalid models. Thanks @azade-c for PR #298.
 - Sub-agents: skip invalid model overrides with a warning and keep the run alive; tool exceptions now return tool errors instead of crashing the agent.
 - Sessions: forward explicit sessionKey through gateway/chat/node bridge to avoid sub-agent sessionId mixups.
