# Claude Code v2.1.132

> Claude Code v2.1.132, released 6 May 2026 (2026-05-06). 13 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

Web version: https://changelogs.core-directive.com/v/2.1.132

This release adds Linux sandbox configuration for custom `bwrap` and `socat` binaries, improves MCP startup handling with a new wait tool behind a rollout flag, and makes WebFetch failures more actionable by returning HTTP status details instead of opaque fetch errors. It also includes several terminal and background-session refinements, plus dark-launched `/goal` infrastructure that is present in the build but not enabled.

## Changes

### Custom Linux Sandbox Binary Paths

**What**

Linux users can now configure exact `bwrap` and `socat` binary paths for sandbox and proxy bridge setup.

**Usage**

`{ "sandbox": { "bwrapPath": "/usr/bin/bwrap", "socatPath": "/usr/bin/socat" } }` **Details** - `bwrapPath` controls the bubblewrap executable used for Linux sandboxing. - `socatPath` controls the executable used for HTTP/SOCKS bridge processes. - Claude Code validates that configured paths are executable and reports clearer errors if not. - This is useful on systems where these tools are installed outside `PATH`, or where a managed environment pins exact binary locations. **Evidence** Sandbox schema adds `bwrapPath` and `socatPath` settings (search for `"Linux only: absolute path to the bwrap"` and `"Linux only: absolute path to the socat binary"`)

### MCP Wait For Servers [Gradual Rollout]

**What**

Claude can wait briefly for MCP servers that are still connecting, then continue once their tools are available.

**Usage**

`Claude calls WaitForMcpServers when an MCP server is still connecting.` **Details** - The new `WaitForMcpServers` tool waits for all pending servers, or for specific server names. - Results distinguish connected, failed, still pending, needs-auth, disabled, and unknown servers. - Missing-tool guidance now tells Claude when a requested MCP tool belongs to a server that is still connecting. - The tool is gated by `tengu_ashen_kelp`, so it may not be visible for every user yet. **Evidence** MCP wait tool and gated enablement (search for `"WaitForMcpServers"` and `"The MCP server '"`)

- Flag `tengu_ashen_kelp`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.132; this account: on, anonymous baseline: on, compiled default: no gate table built for this version) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

### WebFetch HTTP Error Results

WebFetch now returns structured HTTP failure information when a server responds with an error status, including status text and `Retry-After` when present. This should help users distinguish an authentication-required page, a rate limit, and a normal fetch failure without guessing from a generic exception.

**Evidence**

WebFetch HTTP error result text (search for `"The server returned HTTP"` and `"The response body was not retrieved"`)

### Fullscreen Renderer Controls

Terminal fullscreen behavior is more conservative and easier to override. Claude Code now recognizes `CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN` as an explicit opt-out, and it auto-disables fullscreen on Windows-over-SSH ConPTY sessions unless `CLAUDE_CODE_NO_FLICKER=1` is set.

**Evidence**

Fullscreen environment handling (search for `"CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN"` and `"fullscreen disabled: Windows over SSH"`)

### Background Session Detach Key

Background session instructions now consistently use `Ctrl+Z` to detach, replacing older `Ctrl+B then d` and `Ctrl+Q` guidance in redraw/startup messages.

**Evidence**

Background session prompts (search for `"Ctrl+Z to detach"`)

### MCP Connection Resilience

Remote MCP retry behavior now logs recovery and stops retrying once failed remote servers recover. MCP stdio transports also detect excessive non-protocol stdout and disconnect before unbounded memory growth.

**Evidence**

MCP retry and stdout overflow handling (search for `"[MCP] Retry: all remote servers recovered, stopping"` and `"StdoutOverflowError"`)

### Bash Safety Detection

Read-only command validation gained additional shell-edge-case detection, especially around zsh recursive evaluation, array subscripts, assignment side effects, redirect expansion, and escaped brace handling. These checks reduce cases where a command that looks harmless can still execute dynamic shell code.

**Evidence**

Shell safety reasons (search for `"zsh $name[expr]"`, `"assignment alters command lookup/execution"`, and `"Redirect target starts with ="`)

### Long-Running Command Guidance

The Bash tool description now explains `run_in_background` more directly and removes stale advice to read output later immediately. Claude Code also includes stronger guidance to avoid foreground `sleep` and use background commands or Monitor for waiting.

**Evidence**

Background command guidance (search for `"`run_in_background` runs the command detached"` and `"Foreground `sleep` is blocked"`)

### Policy Limit Cache Handling

When policy limits are fetched and no restrictions apply, Claude Code now preserves an explicit cached empty result instead of treating it like a deleted cache file. This should reduce noisy policy-limit cache churn in environments with no active restrictions.

**Evidence**

Policy limit cache message (search for `"Policy limits: No restrictions (cached empty)"`)

### Service Availability Messages

Daemon/service messages now distinguish unsupported installation from on-demand operation, making platform limitations clearer.

**Evidence**

Service messaging (search for `"service install not available on this platform"` and `"service uninstall not available on linux"`)

## Bug Fixes

- WebFetch now reports HTTP status responses as tool results instead of falling through to less-informative request failures (search for `"The server returned HTTP"`)

- MCP stdio servers that write too much non-JSON data to stdout are disconnected with a clear overflow error instead of allowing unbounded buffering (search for `"wrote >"` and `"without a JSON-RPC message boundary"`)

- Fullscreen mode is now disabled automatically for Windows-over-SSH ConPTY sessions where the alternate-screen renderer is known to misbehave (search for `"fullscreen disabled: Windows over SSH"`)

- Policy-limit fetches with no restrictions now cache the empty state instead of deleting the cache on the old 404 path (search for `"Policy limits: No restrictions (cached empty)"`)

## In Development

Features with infrastructure added but not yet enabled. These are shipped "dark" and may become available in future versions.

### Goal Command [In Development]

**What**

A new `/goal` command is being prepared to set a session-scoped stopping condition so Claude keeps working until a stated goal is met.

**Status**

Disabled/stubbed

**Details**

- The implementation adds `/goal <condition>`, `/goal clear`, status rendering, and a session-scoped Stop hook.
- Goal state records the condition, iteration count, and set time.
- The command currently has `isEnabled: () => !1`, so users cannot invoke it in this build.
- The existing `/loops` UI can see and manipulate related Stop-hook entries, but `/goal` itself remains unavailable.

**Evidence**

Disabled goal command implementation (search for `"Set a goal — keep working until the condition is met"` and `"No goal set. Usage: `/goal <condition>`"`)
