[dependabot]

Bumps time-machine from 3.3.1 to 3.4.0.

Changelog

Sourced from time-machine's changelog.

3.4.0 (2026-08-10)

• Publish wheels for Python 3.15.

  Thanks to Edgar Ramírez Mondragón in PR [#655](https://github.com/adamchainz/time-machine/issues/655) <https://github.com/adamchainz/time-machine/pull/655>__.

• Fix a reference leak in the patched datetime.datetime.utcnow() that occurred when its Python 3.12+ DeprecationWarning was raised as an error, such as under -W error. Each such call leaked a reference to the active traveller object.

  PR [#656](https://github.com/adamchainz/time-machine/issues/656) <https://github.com/adamchainz/time-machine/pull/656>__.

• Extend the :ref:Migration CLI <migration-cli> to migrate patterns from freezegun’s pytest plugins, pytest-freezegun and pytest-freezer: the freezer fixture and the pytest.mark.freeze_time marker. Also make it migrate freeze_time() context managers that bind the result with as, including converting tick() method calls to shift().

  PR [#658](https://github.com/adamchainz/time-machine/issues/658) <https://github.com/adamchainz/time-machine/pull/658>. Thanks to Javier Buzzi for the initial work in PR [#562](https://github.com/adamchainz/time-machine/issues/562) <https://github.com/adamchainz/time-machine/pull/562>.

• Fix the :ref:Migration CLI <migration-cli> to handle trailing commas in freeze_time() calls when adding tick=False. Previously, it produced invalid syntax, like travel("2023-01-01",, tick=False).

  PR [#658](https://github.com/adamchainz/time-machine/issues/658) <https://github.com/adamchainz/time-machine/pull/658>__.

• Fix the :ref:Migration CLI <migration-cli> to not indent imports kept from a rewritten from-import when the import doesn’t start its line, such as after if True: on one line. Previously, the kept import gained leading whitespace, producing invalid syntax.

  PR [#658](https://github.com/adamchainz/time-machine/issues/658) <https://github.com/adamchainz/time-machine/pull/658>__.
