Release v0.8.5

Highlights

Protocol integrity. The server no longer writes to stdout, which on the default stdio transport is the JSON-RPC channel. Tree traversal was printing every word of every editable control it encountered, interleaving plain text into the framing the client parses (#359).

Reliability under load. Snapshot and WaitFor tree capture is now size-bounded to prevent hangs and oversized output (#353), the UIA watchdog self-heals after repeated COM failures (#334), and a corrupted comtypes.gen cache from concurrent generation is now handled (#358).

Multi-monitor. Display captures are aligned correctly, annotated captures stay within screenshot bounds, and a structured per-monitor display inventory was added (#303, #329).

Added

• Structured per-monitor display inventory by @zengfanfan in #329
• Explicit-start drag support for Move by @zengfanfan in #328
• WINDOWS_MCP_WATCHDOG switch to disable the UIA watchdog by @mvanhorn in #333
• Strict executable launch by @zengfanfan in #335

Fixed

• Stop writing to stdout, which carries the stdio JSON-RPC protocol by @Jeomon in #359
• Corrupted comtypes.gen cache from concurrent generation by @pranco388 in #358
• Report missing startup dependencies instead of exiting with a bare traceback by @dgonick in #355
• Bound Snapshot/WaitFor tree capture size to prevent hangs and oversized output by @Veloflott in #353
• Self-healing UIA watchdog reconnect on repeated COM failures by @Jeomon in #334
• Multi-monitor snapshot annotations by @sposer and @ackinul in #303
• Raise on failure so isError=true on the MCP wire by @sanjibani in #300
• Retry get_active_window on transient empty UIA results by @Austin519 in #294
• Paste long text via clipboard to avoid SendKeys scan-code race by @Austin519 in #293
• Guard auth banner against non-UTF-8 stdout by @Austin519 in #292
• Reject invalid input boolean values by @zengfanfan in #330

Tests & CI

• Unit test workflow for pull requests by @JezaChen in #343
• Repair broken isError-compliance regression test by @JezaChen in #341

Docs

• Add Autohand Code MCP setup by @igorcosta in #325

Maintenance

• Routine automated dependency bumps
