lxml~=5.3 blocked installation on Python 3.14 (Windows) because no pre-built wheels exist for 5.x on 3.14 and the source build fails without libxml2 headers. lxml 6.x ships Python 3.14 wheels and is already API- compatible (our full regression suite runs on lxml 6.0.2 unchanged). Change ~=5.3 to >=5.3 to allow 6.x, and add Python 3.14 classifier. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Problem
lxml~=5.3resolves to5.4.xwhich has no pre-built wheels for Python 3.14 on Windows. pip falls back to a source build, which fails withoutlibxml2development headers — making crawl4ai uninstallable on Python 3.14.Fix
lxml~=5.3→lxml>=5.3to allow lxml 6.x (which ships Python 3.14 wheels)Programming Language :: Python :: 3.14classifierlxml 6.x is already API-compatible with crawl4ai — our venv runs 6.0.2 and the full regression suite (303 tests) passes unchanged.
