10 * Fixed Bash commands failing with "task output swap refused (tasks dir moved or linked)" on some Macs
11 * Fixed "always allow" not saving in a project that has no .claude/settings.local.json yet
12 * Fixed Remote Control sessions hosted by Claude Desktop or VS Code stalling for minutes after a tool finished when the connection to claude.ai was degraded

1017 * Added `PreModelSwitch` and `PostModelSwitch` hook events (block, confirm, or annotate a model switch); `SessionStart` resume hooks now receive session staleness and the estimated re-cache cost

2058 * Fixed a regression where a custom API gateway could receive the user's Anthropic OAuth credential instead of the gateway's own token
2059 * Fixed subagent (Agent tool) frontmatter MCP servers ignoring `--strict-mcp-config`, `--bare`, remote mode, enterprise managed MCP config, and managed-settings MCP server allow/deny policies
2060 * `--strict-mcp-config` no longer strips inline `mcpServers` from explicitly-passed agent definitions (`--agents` / SDK `agents`), and blocked subagent MCP servers now surface a visible warning
