Of the three packages, the upgrade for nbconvert carries a medium risk due to a change in Python version support. The other upgrades are low risk.

Key Changes

• nbconvert 7.6.0 → 7.17.0 (Medium Risk):
  This upgrade drops support for Python 3.8. The documentation for newer versions states that the supported Python versions are 3.8-3.11, but the changelogs indicate that testing and support for 3.8 were dropped in favor of newer versions. This is an environment change that requires verification.

  • Recommendation: Verify that your project's runtime environment is compatible with the new minimum Python version required by nbconvert.

• mistune 3.0.2 → 3.3.0 (Low Risk):
  This is a minor version upgrade consisting of bug fixes and security enhancements. Changes include fixes for potential Denial of Service (DoS) vulnerabilities, improved HTML escaping, and corrections to plugin behavior. No breaking API changes are noted in this range.

• tornado 6.2 → 6.5.5 (Low Risk):
  This upgrade span consists of several patch and minor releases that introduce security fixes, bug fixes, and type annotation improvements. Key changes include hardening against Denial of Service (DoS) attacks by limiting multipart request parts and stricter header validation. Version 6.5.0 also introduces several deprecations, such as for obs-fold continuation lines in HTTP headers, which will be removed in Tornado 7.0. While not immediately breaking, these deprecations should be noted for future maintenance.
