This update includes a high-risk major version upgrade for pillow and a medium-risk minor upgrade for pyasn1.

pillow 9.5.0 → 12.3.0 (High Risk)

This upgrade spans three major versions (v10, v11, v12) and introduces significant breaking changes requiring code modifications and environment updates.

Key Breaking Changes:

• Python Version Support: Support for Python 3.7 was dropped in v10.0.0, 3.8 in v11.0.0, and 3.9 in v12.0.0. Your environment must be running Python 3.10 or newer.
• Resampling Filter Constants: In v10.0.0, resampling filter constants like Image.ANTIALIAS, Image.BICUBIC, etc., were removed and replaced by an enum, Image.Resampling. For example, Image.ANTIALIAS is now Image.Resampling.LANCZOS. This is a common breaking change that will require code updates where image resizing or transformations occur.
• Removed Modules and Attributes: Numerous deprecated features have been removed across these versions, including im.category, PyAccess, and internal helper classes.

Recommendation: Due to the number of major versions and significant API changes, this upgrade should be tested thoroughly in a development environment. Pay close attention to image processing code, especially resizing operations, and verify your Python runtime environment is compatible.

pyasn1 0.5.1 → 0.6.4 (Medium Risk)

This minor version upgrade drops support for older Python versions.

• Python Version Support: Version 0.6.0 dropped support for Python 2.7, 3.6, and 3.7.
• The upgrade is otherwise focused on bug fixes and minor feature additions. The target version 0.6.4 includes security fixes for Denial-of-Service vulnerabilities present in earlier 0.6.x versions.

Recommendation: The risk is medium primarily due to the dropped support for end-of-life Python versions. Verify that your application is running on a supported Python version (3.8+).
