###
[`v0.28.0`](https://redirect.github.com/encode/httpx/blob/HEAD/CHANGELOG.md#0280-28th-November-2024)

[Compare
Source](https://redirect.github.com/encode/httpx/compare/0.27.2...0.28.0)

The 0.28 release includes a limited set of deprecations.

**Deprecations**:

We are working towards a simplified SSL configuration API.

*For users of the standard `verify=True` or `verify=False` cases, or
`verify=<ssl_context>` case this should require no changes. The
following cases have been deprecated...*

- The `verify` argument as a string argument is now deprecated and will
raise warnings.
-   The `cert` argument is now deprecated and will raise warnings.

Our revised [SSL documentation](docs/advanced/ssl.md) covers how to
implement the same behaviour with a more constrained API.

**The following changes are also included**:

-   The deprecated `proxies` argument has now been removed.
-   The deprecated `app` argument has now been removed.
- JSON request bodies use a compact representation.
([#&#8203;3363](https://redirect.github.com/encode/httpx/issues/3363))
- Review URL percent escape sets, based on WHATWG spec.
([#&#8203;3371](https://redirect.github.com/encode/httpx/issues/3371),
[#&#8203;3373](https://redirect.github.com/encode/httpx/issues/3373))
- Ensure `certifi` and `httpcore` are only imported if required.
([#&#8203;3377](https://redirect.github.com/encode/httpx/issues/3377))
- Treat `socks5h` as a valid proxy scheme.
([#&#8203;3178](https://redirect.github.com/encode/httpx/issues/3178))
- Cleanup `Request()` method signature in line with `client.request()`
and `httpx.request()`.
