Claude Code (Anthropic's terminal coding agent)

  • Version 2.1.166 released 7 minutes ago:
- Added fallbackModel setting to configure up to three fallback models tried in order when the primary model is overloaded or unavailable; also applies to interactive sessions. - Glob pattern support in deny rule tool‑name position (e.g., "* denies all tools); allow rules reject non‑MCP globs, unknown tool names in deny rules warn at startup. - Hardened cross‑session messaging: messages relayed via SendMessage from other Claude sessions no longer carry user authority — receivers refuse relayed permission requests, and auto mode blocks them. - Per‑model thinking toggle now disables thinking on models that think by default via the Claude API (3P providers unchanged); can be set with MAX_THINKING_TOKENS=0 or --thinking disabled. - Claude Code now retries a turn once on the fallback model when the API rejects an unexpected non‑retryable error; auth, rate‑limit, request‑size, and transport errors still surface immediately. - claude update now announces the target version before downloading instead of going silent. - claude agents: typing a URL into the list now filters to the session whose first prompt contained it. - Numerous bug fixes: - Fixed recurring “image could not be processed” error and extra token usage when an unprocessable image was sent. - Fixed remote sessions becoming permanently stuck after a brief backend disruption during worker registration at startup. - Fixed flickering in JetBrains IDE terminals (IntelliJ, PyCharm, WebStorm, etc.) on 2026.1+ by enabling synchronized output. - Fixed Shift+non‑ASCII characters (e.g., Shift+ä → Ä) being dropped in terminals using the Kitty keyboard protocol (WezTerm, Ghostty, kitty). - Fixed PowerShell command validation occasionally hanging far past its time budget on Windows when a killed process's children held its output pipes. - Fixed orphaned claude --bg-pty-host processes spinning at 100% CPU after the daemon dies while connected on macOS. - Fixed voice mode requiring /login to clear a stale auth check after toggling /voice. - Fixed managed settings with an invalid entry silently disabling enforcement of their remaining valid policies. - Fixed managed‑settings allowedMcpServers/deniedMcpServers predicates not matching when they use ${VAR} references. - Fixed background agent sessions that entered a git worktree crash‑looping with “No conversation found” when reopened. - Fixed duplicated thinking text in the Ctrl+O transcript view while streaming. - Fixed the cursor sticking at the end of the first line when typing a multiline prompt in the dispatch and reply inputs.
  • Dynamic Workflows (research preview) introduced June 2, 2026:
- End‑to‑end, parallel task handling across codebases, migrations, and complex engineering work with built‑in verification and saved progress. - Available in Claude Code CLI, Desktop, VS Code extension (Max/Team/Enterprise plans with admin enabled), Claude API, Amazon Bedrock, Vertex AI, and Microsoft Foundry. - Can consume substantially more tokens; start with scoped tasks. - Two ways to start: ask Claude to “create a workflow” or enable the ultracode setting (effort level xhigh) to let Claude decide when to use a workflow. - Example use cases: codebase‑wide bug hunts, large migrations, critical work needing independent verification.
  • Admin permissions for Enterprise custom roles (June 2, 2026):
- Extended custom roles framework with admin permissions, letting members access billing or privacy without Owner access.

OpenAI Codex CLI

  • Version 0.137.0 released June 4, 2026:
- New Features - TUI controls now support F13‑F24 keybindings, paste in searchable menus, and a compact reasoning‑only status/title item. - Enterprise/admin flows show monthly credit limits and can apply cloud‑managed config bundles (including EDU workspaces). - Remote‑control clients can start pairing and list or revoke controller grants through app‑server v2 RPCs. - Plugin workflows gained machine‑readable codex plugin list --json output and cached remote catalog suggestions. - Hosted web and image tools are available in more code‑mode flows; standalone web searches can run in parallel. - Multi‑agent v2 keeps runtime choice per thread and exposes cleaner follow‑up and metadata defaults for spawned agents. - Bug Fixes - Cancelling a submitted prompt before visible output restores the draft, attachments, and collaboration mode for editing. - Slash‑command filtering and footer shortcut hints now reset or render according to the current UI state. - Platform reliability improved for macOS app launches, Windows SQLite startup, thread resume, and sandbox setup refreshes. - Plugin loading preserves app manifest order, deduplicates local/remote curated installs, and treats malformed skills fields as warnings. - Permission requests and approvals now carry environment identity, and managed MITM proxying exports readable CA bundles to child commands. - Local session history is safer for compressed rollouts, renamed titles, pathless side‑chat reloads, and stack‑heavy startup/config rebuilds. - Documentation - Added app‑server docs and generated schema updates for monthly credit limits, remote‑control RPCs, and environment‑scoped permission approvals. - Moved repo review rules and contributor conventions into AGENTS.md, including Rust test‑module layout and Python 3 compatibility guidance. - Chores - Root formatting and Justfile workflows are more complete and Windows‑aware. - Rust CI and release workflows now use the git CLI for Cargo fetches to avoid intermittent libgit2/submodule failures. - Python SDK releases publish runtime wheels from the SDK workflow and pin to a glibc‑compatible runtime package. - Bazel CI’s BuildBuddy wrapper was reintroduced with Windows‑safe process handling and validation. - Shared prompts, context fragments, and skills plumbing moved into dedicated crates/extension paths to reduce codex‑core coupling.
  • Earlier recent versions (0.136.0, 0.135.0, etc.) continue incremental improvements.

OpenCode (opencode‑ai/opencode)

  • Version 1.16.2 released 9 hours ago:
- Core - Reasoning summaries now only run on providers that support them, avoiding GPT‑5 request failures on compatible backends. - Edit operations now refuse loose matches that could overwrite the wrong code or replace an existing file by mistake. - Fixed Bedrock sessions hanging before a model response starts. - Improvements - Diff viewer now supports next and previous hunk navigation. - Terminal themes now refresh after live terminal reloads without stale colors or broken highlighting. - Running subagents can now be sent to the background so you can keep working. - Sessions now persist system context updates during long‑running conversations. - Added Snowflake Cortex provider support. - TUI - Fixed the external editor fallback so attach‑mode sessions still open when the original project path is unavailable locally. - Permission replies now route through the correct session directory. - /mo now prefers the models command in slash autocomplete. - Fixed crashes from malformed path or diff metadata in permission and session views. - Desktop - Fixed titlebar tab overflow clipping. - Fixed overflowed titlebar tabs so scrolling and drag regions behave correctly. - Improved tab closing and navigation so the next tab is selected more reliably. - Improved multi‑server desktop support with per‑server home state and session tabs. - Thank you to contributors: @kameshsampath, @pcadena‑lila, @weiconghe, @alblez, @jerome‑benoit.
