3.7.4 (2021-02-25)

Bugfixes

• (SECURITY BUG) Started preventing open redirects in the aiohttp.web.normalize_path_middleware middleware. For more details, see GHSA-v6wp-4m6f-gcjg.

  Thanks to Beast Glatisant for finding the first instance of this issue and Jelmer Vernooij for reporting and tracking it down in aiohttp. #5497

• Fix interpretation difference of the pure-Python and the Cython-based HTTP parsers construct a yarl.URL object for HTTP request-target.

  Before this fix, the Python parser would turn the URI's absolute-path for //some-path into / while the Cython code preserved it as //some-path. Now, both do the latter. #5498
