Changelog for Rust SDK

## 0.9.0 *October 22, 2026* | Type | Changes | |------|----------| | **Added** | • Add `ChannelsCategoryPermission` and `UuidsCategoryPermission`, the `categories` option for `grant_token`, and parsing of category permissions in `parse_token`. Parsed token `resources` and `patterns` are optional now. • Allow `Permission` implementations to be shared across threads. | | **Fixed** | • Fix `DataStream` deadlock between `push_data` and `poll_next` which took `queue` and `waker` locks in opposite order, and `EventDispatcher` deadlock between stream creation and `invalidate`. | | **Modified** | • Remove redundant references in `format!` arguments of `PubNubClientInstance`, access and presence request builders. • Replace `r#type` with `custom_message_type` publish setter sent as `custom_message_type` query param. Received `Message` exposes the same field, and examples and docs use the new name. • Unknown `e` values and malformed envelopes are skipped instead of failing the whole subscribe response. Payload is picked by event type first, then by `-pnpres` channel suffix. • Add `keywords`, enable `access` feature by default, update `wiremock` and `cucumber`, and register the `integration` test target. • Update `README.md` PubNub Rust SDK header. • Add unit and integration tests for categories-only grants, all permission kinds, token parsing and malformed tokens. • Add tests for `DataStream` and `EventDispatcher` lock ordering, listener wake-ups and delivery of dispatched batches. • Cover type-first classification, presence channel suffix, unknown event types, malformed entries and message action `added` and `removed` events. | ## 0.8.0 *June 8, 2026* | Type | Changes | |------|----------| | **Added** | • Enable HTTP/2 negotiation on the default `TransportReqwest` by turning on reqwest’s `native-tls-alpn` feature, so ALPN can select `h2` when the origin supports it while preserving HTTP/1.1 fallback. | | **Fixed** | • Fix a Clippy `derivable_impls` lint in `RequestRetryConfiguration` (derive `Default` on the enum instead of a manual impl). | | **Modified** | • Add debug-level protocol logging in async and blocking `TransportReqwest::send()` after each completed request, including HTTP method, path, and the Reqwest-reported protocol version. | ## 0.7.0 *October 28, 2025* | Type | Changes | |------|----------| | **Added** | • Add `limit` (default `1000`) and `offset` parameters for `here_now` to fetch presence in portions. • Use default retry configuration for `subscribe` and `presence` REST API calls. | | **Fixed** | • Fix the issue because of which it was possible to add the same channel / group multiple times to the `subscribe`, `heartbeat`, or `leave` requests. • Fix the `Presence` enum variant to not intercept user-published messages that partly match the `Presence` variant. | | **Modified** | • Synchronize subscription flow with other SDKs. • Synchronize presence flow with other SDKs. | ## 0.6.0 *February 7, 2024* | Type | Changes | |------|----------| | **Added** | • Make it possible to create `SubscriptionCursor` from the string slice. • Add `add_subscriptions(..)` and `sub_subscriptions(..)` to `SubscriptionSet` to make it possible in addition to sets manipulation use list of subscriptions. | | **Fixed** | • Fix issue because of which `cursor` is not reset on `Subscription` and `SubscriptionSet` on unsubscribe. • Fix issue because of which cancelled effects still asynchronously spawned for processing. | | **Modified** | • Change `client` to `pubnub` in inline docs. • Add subscription token validation. • Added a method to validate the provided subscription token to conform to PubNub time token requirements with precision. • Separate `subscribe` example into two to show separately `subscribe` feature and `presence state` maintenance with subscribe. | ## 0.5.0 *January 25, 2024* | Type | Changes | |------|----------| | **Added** | • Change the real-time event handling interface. • `user_id` state for specified channels will be maintained by the SDK. State with subscribe calls has been improved. • Adding `Channel`, `ChannelGroup`, `ChannelMetadata` and `UuidMetadata` entities to be first-class citizens to access APIs related to them. Currently, access is provided only for subscription APIs. • Added ability to configure request retry policies to exclude specific endpoints from retry. | ## 0.4.1 *November 3, 2023* | Type | Changes | |------|----------| | **Modified** | • Update license information. | ## 0.4.0 *October 16, 2023* | Type | Changes | |------|----------| | **Added** | • Update the crypto module structure and add enhanced AES-CBC cryptor. | ## 0.3.0 *August 30, 2023* | Type | Changes | |------|----------| | **Added** | • PubNub subscribe API implemented. • PubNub presence API implemented. • Event engine as a new method of handling connections for `subscribe` and `presence` methods implemented. | ## 0.2.1 *June 7, 2023* | Type | Changes | |------|----------| | **Fixed** | • Fixed versions in the docs. • Fixed broken links for `docs.rs` page. • Fixed logo image. | ## 0.2.0 *June 5, 2023* | Type | Changes | |------|----------| | **Added** | • New SDK implementation. • PubNub `publish` API implemented. • PubNub `access manager` API implemented. • Add `parse_token` for authorization token debug. |

Added	Add `ChannelsCategoryPermission` and `UuidsCategoryPermission`, the `categories` option for `grant_token`, and parsing of category permissions in `parse_token`. Parsed token `resources` and `patterns` are optional now. Allow `Permission` implementations to be shared across threads.
Fixed	Fix `DataStream` deadlock between `push_data` and `poll_next` which took `queue` and `waker` locks in opposite order, and `EventDispatcher` deadlock between stream creation and `invalidate`.
Modified	Remove redundant references in `format!` arguments of `PubNubClientInstance`, access and presence request builders. Replace `r#type` with `custom_message_type` publish setter sent as `custom_message_type` query param. Received `Message` exposes the same field, and examples and docs use the new name. Unknown `e` values and malformed envelopes are skipped instead of failing the whole subscribe response. Payload is picked by event type first, then by `-pnpres` channel suffix. Add `keywords`, enable `access` feature by default, update `wiremock` and `cucumber`, and register the `integration` test target. Update `README.md` PubNub Rust SDK header. Add unit and integration tests for categories-only grants, all permission kinds, token parsing and malformed tokens. Add tests for `DataStream` and `EventDispatcher` lock ordering, listener wake-ups and delivery of dispatched batches. Cover type-first classification, presence channel suffix, unknown event types, malformed entries and message action `added` and `removed` events.

Added	Enable HTTP/2 negotiation on the default `TransportReqwest` by turning on reqwest’s `native-tls-alpn` feature, so ALPN can select `h2` when the origin supports it while preserving HTTP/1.1 fallback.
Fixed	Fix a Clippy `derivable_impls` lint in `RequestRetryConfiguration` (derive `Default` on the enum instead of a manual impl).
Modified	Add debug-level protocol logging in async and blocking `TransportReqwest::send()` after each completed request, including HTTP method, path, and the Reqwest-reported protocol version.

Added	Add `limit` (default `1000`) and `offset` parameters for `here_now` to fetch presence in portions. Use default retry configuration for `subscribe` and `presence` REST API calls.
Fixed	Fix the issue because of which it was possible to add the same channel / group multiple times to the `subscribe`, `heartbeat`, or `leave` requests. Fix the `Presence` enum variant to not intercept user-published messages that partly match the `Presence` variant.
Modified	Synchronize subscription flow with other SDKs. Synchronize presence flow with other SDKs.

Added	Make it possible to create `SubscriptionCursor` from the string slice. Add `add_subscriptions(..)` and `sub_subscriptions(..)` to `SubscriptionSet` to make it possible in addition to sets manipulation use list of subscriptions.
Fixed	Fix issue because of which `cursor` is not reset on `Subscription` and `SubscriptionSet` on unsubscribe. Fix issue because of which cancelled effects still asynchronously spawned for processing.
Modified	Change `client` to `pubnub` in inline docs. Add subscription token validation. Added a method to validate the provided subscription token to conform to PubNub time token requirements with precision. Separate `subscribe` example into two to show separately `subscribe` feature and `presence state` maintenance with subscribe.
