## 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 |
