+# 0.2.87 — 2026-07-05
+
+## Features
+
+- **Subscription upgrades** are now detected automatically without restarting the CLI.
+- **Bash permission prompts** now offer a "Never allow" choice that persists the deny rule.
+- **New `/docs` slash command** opens How-to Guides picker, browses web docs, or jumps directly to a guide by title.
+- **Per-model reasoning effort menus** are now configurable from the server and config.toml without a client release.
+- **Finished thinking blocks** now fold into grouped tool-call rows when group_tool_verbs is enabled.
+
+## Bug Fixes
+
+- **--minimal** mode now always uses your terminal's own colors so text stays readable on any background.
+- **Invalid fields** in [model.*] config blocks no longer cause the whole model to disappear from the picker.
+- **File tools** no longer target paths with literal trailing newlines or whitespace from model output.
+- **Fixed interactions** in no-freeform question modals so clicks below the last option no longer enter input mode.
+- **Background tasks** now correctly wake the agent after a cancelled blocking wait instead of staying idle.
+- **Copying quoted text** from rendered responses no longer includes the quote bar prefix in pretty mode.
