+## [v1.59.0] - 2026-05-13
+
+This release adds XML tool call parsing for better model compatibility, performance improvements for TUI rendering, and enhanced remote runtime capabilities.
+
+## What's New
+
+- Adds XML tool call fallback parsing for models that return `<tool_call>...</tool_call>` text instead of using OpenAI function-calling API
+- Adds fd:// scheme support to server.Listen for parent process socket passing
+- Adds per-code-block copy affordance with clickable copy glyphs in TUI
+- Adds session persistence and resumption for A2A (agent-to-agent) interactions using SQLite
+- Adds comprehensive remote runtime API with SSE event streaming, session management, and graceful degradation
+
+## Improvements
+
+- Improves TUI rendering performance with cached output, targeted invalidation, and incremental markdown rendering
+- Improves ACP support with session management, event handling, and structured error codes
+- Preserves user input across tab switches in TUI dialogs
+
+## Bug Fixes
+
+- Fixes crash during tool auto-install by adding panic recovery
+- Fixes SSE stream cancellation and IPv6 address binding issues
+- Fixes Vertex AI Model Garden provider capability lookups by rewriting provider to publisher mapping
+
+## Technical Changes
+
+- Replaces internal secretsscan with github.com/docker/portcullis library
+- Centralizes modelsdev.Store creation via RuntimeConfig with lazy initialization
+- Merges modelcaps into modelinfo and introduces strongly-typed modelsdev.ID
+- Refactors event handling to use EventSink interface instead of channel threading
+- Removes experimental send, watch, and proto subcommands
+
