Fedora 44 python-libcst Important Update RUSTSEC Fixes 2026-17c484fafa

Update to 1.8.6. Build with PyO3 (fixes RUSTSEC-2026-0176, RUSTSEC-2026-0177).. -------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-17c484fafa 2026-07-18 00:26:14.272987+00:00 -------------------------------------------------------------------------------- Name : python-libcst Product : Fedora 44 Version : 1.8.6 Release : 4.fc44 URL : https://github.com/Instagram/LibCST Summary : A concrete syntax tree with AST-like properties for Python 3 Description : LibCST parses Python source code as a CST tree that keeps all formatting details (comments, whitespaces, parentheses, etc). It's useful for building automated refactoring (codemod) applications and linters. LibCST creates a compromise between an Abstract Syntax Tree (AST) and a traditional Concrete Syntax Tree (CST). By carefully reorganizing and naming node types and fields, it creates a lossless CST that looks and feels like an AST. -------------------------------------------------------------------------------- Update Information: Update to 1.8.6.
