Changelog for python3-build: 1.5.1 -> 1.6.0
Source: CHANGELOG.rst

1.6.0 (2026-08-27)
- Pass ``--dependency-constraints-txt`` files through to the installer unmodified instead of re-parsing them into a
  deduplicated set of lines, fixing a case where a hashed requirement (e.g. from ``pip-compile --generate-hashes``) could
  have its ``--hash`` continuation line separated from its requirement line and silently dropped, depending on the
  interpreter's hash seed - by :user:`manfred-kaiser` (:issue:`1140`)
**********
 Removals

- Remove ``exc_info`` parameter and attribute from ``BuildBackendException``. - by :user:`layday` (:issue:`1161`)
