v0.4.9
Two fixes.
- Multi-turn conversations with thinking enabled no longer 400 on Anthropic. Anthropic signs each thinking block and requires the signature echoed back when the block is replayed in history — so the second turn of any thinking conversation (and any thinking + tool-use turn) failed with
messages.N.content.0.thinking.signature: Field required. The provider now captures the signature and sends it back; an unsigned thinking block is dropped rather than sent unsigned. - Text selection works again in macOS Terminal.app. Terminal.app doesn't report mouse-motion events (xterm mode 1003) that Textual needs for in-app drag-select, so capturing the mouse there left you unable to select at all. Mouse capture now defaults OFF on Terminal.app (native click-drag select + copy; scroll with PageUp/PageDown) and ON elsewhere (wheel-scroll + in-app drag-select).
