Bumps com.squareup.retrofit2:converter-gson from 2.9.0 to 3.0.0.

Release notes

Sourced from com.squareup.retrofit2:converter-gson's releases.

3.0.0

Changed

• Upgrade to OkHttp 4.12 (from 3.14).

  This is the version of OkHttp that is written in Kotlin, and as a result Retrofit now has a transitive Kotlin dependency. However, this is also the supported version of OkHttp whereas the previous version was out of support for nearly 4 years.

Note: The 3.x versions of Retrofit maintain forward binary-compatibility with the 2.x versions. This means libraries compiled against 2.x can still be used with the 3.x versions.

2.12.0

New

• First-party converters now support deferring serialization to happen when the request body is written (i.e., during HTTP execution) rather than when the HTTP request is created. In some cases this moves conversion from a calling thread to a background thread, such as in the case when using Call.enqueue directly.

  The following converters support this feature through a new withStreaming() factory method:

  • Gson
  • Jackson
  • Moshi
  • Protobuf
  • Wire

Fixed

• Primitive types used with @Tag now work by storing the value boxed with the boxed class as the key.

2.11.0

New

• The built-in OptionalConverterFactory is now public to allow installing it before other converters which consume all types (e.g., Moshi, Gson, Jackson, etc.).

Fixed

• Ensure that exceptions thrown from failure to parse method annotations can be observed by multiple threads/callers. Previously only the first caller would see the actual parsing exception and other callers would get a cryptic ClassCastException.

2.10.0

New

• Support using Unit as a response type. This can be used for non-body HTTP methods like HEAD or body-containing HTTP methods like GET where the body will be discarded without deserialization.

• kotlinx.serialization converter!

  This was imported from github.com/JakeWharton/retrofit2-kotlinx-serialization-converter/ and remains unchanged from its 1.0.0 release.

  The Maven coordinates are com.squareup.retrofit2:converter-kotlinx-serialization.

• JAXB 3 converter!

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
