    🔄 Changed

    • Cleaned up expected behaviour for URL escaping. url.path is now URL escaped. (Pull #1285)
    • Cleaned up expected behaviour for bytes vs str in URL components. url.userinfo and url.query are not URL escaped, and so return bytes. (Pull #1285)
    • ⬇️ Drop url.authority property in favour of url.netloc, since "authority" was semantically incorrect. (Pull #1285)
    • Drop url.full_path property in favour of url.raw_path, for better consistency with other parts of the API. (Pull #1285)
    • 0️⃣ No longer use the chardet library for auto-detecting charsets, instead defaulting to a simpler approach when no charset is specified. (#1269)

    🛠 Fixed

    • Swapped ordering of redirects and authentication flow. (Pull #1267)
    • .netrc lookups should use host, not host+port. (Pull #1298)

    ✂ Removed

    • The URLLib3Transport class no longer exists. We've published it instead as an example of a custom transport class. (Pull #1182)
    • ⬇️ Drop request.timer attribute, which was being used internally to set response.elapsed. (Pull #1249)
    • ⬇️ Drop response.decoder attribute, which was being used internally. (Pull #1276)
    • Request.prepare() is now a private method. (Pull #1284)
    • 🚚 The Headers.getlist() method had previously been deprecated in favour of Headers.get_list(). It is now fully removed.
    • 🚚 The QueryParams.getlist() method had previously been deprecated in favour of QueryParams.get_list(). It is now fully removed.
    • 🚚 The URL.is_ssl property had previously been deprecated in favour of URL.scheme == "https". It is now fully removed.
    • 🚚 The httpx.PoolLimits class had previously been deprecated in favour of httpx.Limits. It is now fully removed.
    • 🗄 The max_keepalive setting had previously been deprecated in favour of the more explicit max_keepalive_connections. It is now fully removed.
    • 💅 The verbose httpx.Timeout(5.0, connect_timeout=60.0) style had previously been deprecated in favour of httpx.Timeout(5.0, connect=60.0). It is now fully removed.
    • 👌 Support for instantiating a timeout config missing some defaults, such as httpx.Timeout(connect=60.0), had previously been deprecated in favour of enforcing a more explicit style, such as httpx.Timeout(5.0, connect=60.0). This is now strictly enforced.
