From 11248ecea33adf774ab35dcac9636e905d965e96 Mon Sep 17 00:00:00 2001 From: Maxime Grenu Date: Tue, 24 Feb 2026 17:12:59 +0100 Subject: [PATCH 1/2] feat: add Python 3.13 and 3.14 support - Add Python 3.13 and 3.14 to CI test matrix (Mac ARM64, Linux x64, Linux ARM64) - Add classifiers for Python 3.13 and 3.14 - Add cp313 to cibuildwheel build targets - Update ruff target-version to py313 - Add benchmark script for Python 3.14 features (compression.zstd, base64.z85) - Add documentation for Python 3.14 feature compatibility Co-Authored-By: Claude Opus 4.6 --- .github/workflows/linux_arm64_docker_ci.yml | 4 +- .github/workflows/linux_x64_docker_ci.yml | 5 +- .github/workflows/mac_arm64_ci.yml | 2 +- benchmark_python_features.py | 161 ++++++++++++++++++++ docs/PYTHON_3.14_FEATURES.md | 100 ++++++++++++ pyproject.toml | 6 +- python/tests/test_embedding.py | 8 +- 7 files changed, 277 insertions(+), 9 deletions(-) create mode 100644 benchmark_python_features.py create mode 100644 docs/PYTHON_3.14_FEATURES.md diff --git a/.github/workflows/linux_arm64_docker_ci.yml b/.github/workflows/linux_arm64_docker_ci.yml index 4e6b61cf..c7d8d4e3 100644 --- a/.github/workflows/linux_arm64_docker_ci.yml +++ b/.github/workflows/linux_arm64_docker_ci.yml @@ -26,7 +26,7 @@ jobs: strategy: matrix: -
