Web now supports uploads of arbitrary file types: files and images share a preview area, background uploads expose progress and cancellation and remain visible across conversation switches, and models can use existing file tools to read saved paths on demand. by @CreatixChu
All outbound network requests honor the HTTP_PROXY, HTTPS_PROXY, ALL_PROXY, and NO_PROXY settings from the startup environment. by @LegGasai
The Python SDK adds a macOS x64 runtime wheel, allowing Intel-based Macs to install and run the bundled runtime. by @koalazf99
Render images directly in Web tool cards for top-level and PTC-nested read_image calls instead of showing raw attachment objects. by @Chinesezjc
Model discovery now supports models objects from custom model providers and native Anthropic model lists, and fills in model names, context windows, and maximum output tokens when needed. by @LegGasai

Immediately abort the active model turn when a goal is paused manually in Web, preventing the running model from continuing or resuming within the same turn. by @mektpoy
Preserve tool-call IDs and names across DeepSeek streaming continuation chunks, preventing empty tool names and conversation records that cannot be reopened. by @LegGasai
Prevent the Python SDK single-file runtime from rewriting Bash commands that begin with node as dsh runtime invocations. by @imccyu
Open a conversation selected from search in its Workspace, expand it, and scroll it into view instead of leaving the search interface open. by @Dudu-0223
Fix path separators, titles, and absolute-path validation for Windows drive-root Workspaces so drive roots work correctly. by @turtle1999
Fix Session cache reads. by @imccyu

The Skill picker supports fuzzy search, with improved Skill and command references in chat bubbles. by @LegGasai
Unify colors, hover and focus states, and category icons for clickable conversation links, making Markdown links, file references, web sources, artifact links, and Workflow member links easier to distinguish. by @yixiangihsiang
Standardize FS_NOT_OBSERVED diagnostics for unobserved file writes and failed edits while preserving the file path, structured error code, and original cause. by @turtle1999
Prevent local non-terminal subprocesses from opening console windows on Windows. by @turtle1999
Agent Team send_message consistently uses steer semantics and preserves sender attribution and ordering across agents and cold recovery. by @Dudu-0223

Breaking change: The Session persistence API is now owned by lifecycle-scoped SessionHandles; agentLoop.create() is asynchronous, and a new Session lock ensures that each Session is held by at most one process. by @turtle1999
Upgrade the Session format to v2: immutable adjacent-generation migrations convert v0/v1 logs to the current format, Assistant streams are aggregated by attempt into durable settlements, and Web preserves real-time incremental rendering. by @tianyicui
This release has a known performance regression that may affect responsiveness in some scenarios. We will address it in the next release.
