* Libs/Kotlin **(Breaking)**: In the 4 `*Patch` patch models, nullable fields are of type `MaybeUnset<T>` instead of `T`. call `MaybeUnset.Present(val)` to initialize this value
* Libs/Kotlin **(Breaking)**: `SvixOptions` no longer has `initialRetryDelayMillis` or `numRetries` instead use `retrySchedule`
* Libs/Kotlin **(Breaking)**: All `{Resource}{Operation}Options` and model classes (`ApplicationIn`/`MessageOut`) are now data classes
* Libs/Kotlin **(Breaking)**: Deprecated functions `MessageAttempt.list` and `MessageAttempt.listAttemptsForEndpoint` are removed
* Libs/Kotlin **(Breaking)**: All uses of `java.time.OffsetDateTime` replaced with `kotlinx.datetime.Instant`

* Libs/Go: Fix a null-pointer deference regression introduced in previous version.

* Libs/Rust: Fix regression in previous version. Nullable fields are now `Option<T>` instead of `T`, this affects `ListResponseXXXOut.iterator` and `EnvironmentOut.settings`

This version contains a big overhaul of the client libraries, with improved typing.

* Libs/Go: Add `Authentication.ExpireAll` (and `ExpireAllWithOptions`)
* Libs/Go **(Breaking)**: Excluding specific fields on the *Patch models (`ApplicationPatch` for example), all `Nullable{Type}` removed from the models

* Libs/Go **(Breaking)**: All custom model types are now imported from `github.com/svix/svix-webhooks/go/models` instead of `github.com/svix/svix-webhooks/go`
* Libs/Go **(Breaking)**: All `-WithOptions` methods are now removed. Their regular counterparts now take a pointer to an Options type which can be nil when not needed. For example in `Endpoint.RecoverWithOptions` is now `Endpoint.Recover`

* Libs/C **(Breaking)**: All redundant interfaces along with the `Svix.Abstractions` namespace are removed
* Libs/C **(Breaking)**: The `Svix.Model` and `Svix.Models` namespaces are now merged into a single `Svix.Models` namespace
* Libs/C **(Breaking)**: The `Svix.Client` namespace is removed, The `SvixClient` class can now be found in the `Svix` namespace

* Libs/Python **(Breaking)**: `PostOptions` and `ListOptions` are no longer used in methods for `Authentication`,`Endpoint`,`EventType`,`Integration`,`MessageAttempt`,`Message`, `Statistics` and `OperationalWebhookEndpoint` resources. Instead each API call now has its own `{Resource}{Operation}Options`. (Both sync and async)
* Libs/Python: In `Application` the `dashboard_access` method is deprecated in favor of `app_portal_access`. (Both sync and async)
* Libs/Python **(Breaking)**: `EndpointStatsOptions` is renamed to `EndpointGetStatsOptions`
* Libs/Python **(Breaking)**: `MessageAttemptListOptions` is removed in favor of call specific `{Resource}{Operation}Options`

* Libs/Kotlin **(Breaking)**: Update `recover` to return `RecoverOut` (instead of nothing)
* Libs/Kotlin **(Breaking)**: Update `replayMissing` to return `ReplayOut` (instead of nothing)
* Libs/Kotlin **(Breaking)**: Update `sendExample` to return `MessageOut` (instead of nothing)
* Libs/Kotlin **(Breaking)**: Update `MessageAttempt` list methods to each have its own type for
list options, since they don't all support the exact same set of parameters and some of the
parameters that could be set before would just get ignored
* Libs/Kotlin: Fix a bug in `EventType.list` where `options.order` was not getting honored

* Libs/Rust **(Breaking)**: Add optional `EventTypeDeleteOptions` parameter to `EventType::delete`
* Libs/Rust **(Breaking)**: Add optional `options` parameters to `Endpoint::recover`,
`Endpoint::rotate_secret`, `Integration::rotate_key` and `MessageAttempt::resend`

through the `Svix` object
* Libs/Rust **(Breaking)**: Switch `Patch` struct fields from `Option<Option<T>>` to
`js_option::JsOption<T>`
