## Added

- Added a `OpenError::DictionaryDoesNotExist` error variant, which identifies when a dictionary couldn't be found.
- Added `Dictionary::try_open()`, which returns a `Result`, allowing programs to explicitly handle open failures.
- Added automatic gzip decompression for backend responses; see `Request::set_auto_decompress_gzip()`.
- Added `Request::get_query_parameter()` for easy access to individual query parameter strings.
- Added `get_ttl()` and `get_stale_while_revalidate()` accessors for `CacheOverride`.

## Changed

- Renamed `with_body_bytes()` and `set_body_bytes()` methods to `with_body_octet_stream()` and `set_body_octet_stream()` to emphasize that they modify the `Content-Type` of the request or response. The original names are still present, but deprecated.
- When reading from an HTTP body, an unexpected EOF (e.g., if a backend disconnects) results in an appropriately-tagged `std::io::Error` rather than the generic `"fastly_http_body::read failed"`.

## Fixed

- Panics caused when request limits are exceeded in `Request::from_client()` or the `#[fastly::main]` macro now log a more informative error message; previously it was reported as `panicked at 'explicit panic'`.
