semgrep 1.140.0

Release v1.140.0

on Python PyPI

1.140.0 - 2025-10-16

Added

• scala: Allow partial case patterns such as case 1 => ... to easily match
  individual case clauses within a match-expression. (code-9118)
• Added python 3.14 support. (gh-11250)
• MCP: Slash command setup_semgrep_mcp now supports Claude Code. (saf-2261)

Changed

• Semgrep's Docker image base has been bumped from Alpine Linux 3.21 to 3.22 (docker-version)

Fixed

• Java and Rust: Fixed parsing of float and double literals with type suffixes so they can be used in metavariable-comparison and pattern matching. Previously, Java literals like 0.5f or 1.0d, and Rust literals like 0.5f32 or 1.0f64 would fail to parse and could not be compared. (gh-7968)
• Display an error instead of a malformed success message
  when the show subcommand fails due to an invalid CLI token. (grow-630)
• new semgrep/semgrep images should now contain golang v1.24 instead of v1.23 (saf-2240)
• Fixed an issue where temporary files, containing rules to be validated,
  persisted after a semgrep scan. (saf-2257)
• MCP: Fixed tool calls failing for some models (e.g., GPT-5). (saf-2262)
• MCP: Fixed a bug where resource closure errors would occur when trying to use
  the MCP with the streamable-http tranport method. (saf-2264)
