  • v1.26.8 Changes

    January 07, 2022
    • ➕ Added extra message to urllib3.exceptions.ProxyError when urllib3 detects that a proxy is configured to use HTTPS but the proxy itself appears to only use HTTP.
    • ➕ Added a mention of the size of the connection pool when discarding a connection due to the pool being full.
    • ➕ Added explicit support for Python 3.11.
    • 0️⃣ Deprecated the Retry.MAX_BACKOFF class property in favor of Retry.DEFAULT_MAX_BACKOFF to better match the rest of the default parameter names. Retry.MAX_BACKOFF is removed in v2.0.
    • 📦 Changed location of the vendored ssl.match_hostname function from urllib3.packages.ssl_match_hostname to urllib3.util.ssl_match_hostname to ensure Python 3.10+ compatibility after being repackaged by downstream distributors.

    the same socket.send() call (Pull #1906)

    0️⃣ Send http/1.1 ALPN identifier with every TLS handshake by default (Pull #1894)

    into an urllib3.exceptions.SSLError (Pull #1939)

  • v1.25.11 Changes

    October 19, 2020

    🛠 Fix retry backoff time parsed from Retry-After header when given in the HTTP date format. The HTTP date was parsed as the local timezone rather than accounting for the timezone in the HTTP date (typically UTC) (#1932, #1935, #1938, #1949)

    🛠 Fix issue where an error would be raised when the SSLKEYLOGFILE environment variable was set to the empty string. Now SSLContext.keylog_file is not set in this situation (#2016)
