Svix

* Libs/Java **(Breaking)**: The type of `MessageIn.transformationsParams` changed from `Object` to `Map<String,Object>`.
* Libs/Java and Libs/Kotlin **(Breaking)**: Due to an internal change in the underlining JSON de/serialization library, some JSON objects may not be serialized correctly. To address this `MessageIn.payload` now accepts a JSON encoded string instead of an `Object` (for Java) or `Map<String, Any>` (for Kotlin)
* Libs/Go: Fix regression in Go lib, operations now return `&svix.Error` instead of `svix.Error`

* Libs/Ruby **(Breaking)**: Ruby version changed from `2.7` to `3.4.2`
* Libs/Ruby **(Breaking)**: Deprecated methods `MessageAttempt.list` and `MessageAttempt.list_attempts_for_endpoint` are removed

* Libs/Javascript: Fix regression causing json deserialization to throw exception in a few edge cases

* Libs/Java **(Breaking)**: All uses of `ListOptions`/`PostOptions` are removed, and renamed to `{Resource}{Operation}Options`. For example in `Endpoint.List` you would now use `EndpointListOptions`
* Libs/Java **(Breaking)**: Deprecated methods `MessageAttempt.list` and `MessageAttempt.listAttemptsForEndpoint` are removed

* Libs/Go: Fixed regression where go >= 1.23 was needed, now Go >= 1.21 is supported

* Libs/JavaScript: Fixed regression introduced in version 1.59.0, types are now correctly exported
