# Changes

## Unreleased

- Add `session.update(key, updater)`
- Add `session.update_or(key, updater, default_value)`
- Add `session.contains_key(key)`

## 0.10.1

- Expose `storage::generate_session_key()` without needing to enable a crate feature.

## 0.10.0

- Add `redis-session-rustls` crate feature that enables `rustls`-secured Redis sessions.
- Add `redis-pool` crate feature (off-by-default) which enables `RedisSessionStore::{new, builder}_pooled()` constructors.
- Rename `redis-rs-session` crate feature to `redis-session`.
- Rename `redis-rs-tls-session` crate feature to `redis-session-native-tls`.
- Remove `redis-actor-session` crate feature (and, therefore, the `actix-redis` based storage backend).
- Expose `storage::generate_session_key()`.
- Update `redis` dependency to `0.26`.

## 0.9.0

- Remove use of `async-trait` on `SessionStore` trait.
- Minimum supported Rust version (MSRV) is now 1.75.

## 0.8.0

- Set secure attribute when adding a session removal cookie.
- Update `redis` dependency to `0.23`.
- Minimum supported Rust version (MSRV) is now 1.68.

## 0.7.2

- Set SameSite attribute when adding a session removal cookie. [#284]
- Minimum supported Rust version (MSRV) is now 1.59 due to transitive `time` dependency.

[#284]: https://github.com/actix/actix-extras/pull/284

## 0.7.1

- Fix interaction between session state changes and renewal. [#265]

[#265]: https://github.com/actix/actix-extras/pull/265

## 0.7.0

- Added `TtlExtensionPolicy` enum to support different strategies for extending the TTL attached to the session state. `TtlExtensionPolicy::OnEveryRequest` now allows for long-lived sessions that do not expire if the user remains active. [#233]
- `SessionLength` is now called `SessionLifecycle`. [#233]
- `SessionLength::Predetermined` is now called `SessionLifecycle::PersistentSession`. [#233]
- The fields for Both `SessionLength` variants have been extracted into separate types (`PersistentSession` and `BrowserSession`). All fields are now private, manipulated via methods, to allow adding more configuration parameters in the future in a non-breaking fashion. [#233]
- `SessionLength::Predetermined::max_session_length` is now called `PersistentSession::session_ttl`. [#233]
- `SessionLength::BrowserSession::state_ttl` is now called `BrowserSession::session_state_ttl`. [#233]
- `SessionMiddlewareBuilder::max_session_length` is now called `SessionMiddlewareBuilder::session_lifecycle`. [#233]
- The `SessionStore` trait requires the implementation of a new method, `SessionStore::update_ttl`. [#233]
- All types used to configure `SessionMiddleware` have been moved to the `config` sub-module. [#233]
- Update `actix` dependency to `0.13`.
- Update `actix-redis` dependency to `0.12`.
- Minimum supported Rust version (MSRV) is now 1.57 due to transitive `time` dependency.

[#233]: https://github.com/actix/actix-extras/pull/233

## 0.6.2

- Implement `SessionExt` for `GuardContext`. [#234]
- `RedisSessionStore` will prevent connection timeouts from causing user-visible errors. [#235]
- Do not leak internal implementation details to callers when errors occur. [#236]

[#234]: https://github.com/actix/actix-extras/pull/234
[#236]: https://github.com/actix/actix-extras/pull/236
[#235]: https://github.com/actix/actix-extras/pull/235

## 0.6.1

- No significant changes since `0.6.0`.

## 0.6.0

### Added

- `SessionMiddleware`, a middleware to provide support for saving/updating/deleting session state against a pluggable storage backend (see `SessionStore` trait). [#212]
- `CookieSessionStore`, a cookie-based backend to store session state. [#212]
- `RedisActorSessionStore`, a Redis-based backend to store session state powered by `actix-redis`. [#212]
- `RedisSessionStore`, a Redis-based backend to store session state powered by `redis-rs`. [#212]
- Add TLS support for Redis via `RedisSessionStore`. [#212]
- Implement `SessionExt` for `ServiceResponse`. [#212]

### Changed

- Rename `UserSession` to `SessionExt`. [#212]

### Removed

- `CookieSession`; replaced with `CookieSessionStore`, a storage backend for `SessionMiddleware`. [#212]
- `Session::set_session`; use `Session::insert` to modify the session state. [#212]

[#212]: https://github.com/actix/actix-extras/pull/212

## 0.5.0-beta.7

- Update `actix-web` dependency to `4.0.0.beta-18`. [#218]
- Minimum supported Rust version (MSRV) is now 1.54.

[#218]: https://github.com/actix/actix-extras/pull/218

## 0.5.0-beta.6

- Update `actix-web` dependency to `4.0.0.beta-15`. [#216]

## 0.5.0-beta.5

- Update `actix-web` dependency to `4.0.0.beta-14`. [#209]
- Remove `UserSession` implementation for `RequestHead`. [#209]
- A session will be created in the storage backend if and only if there is some data inside the session state. This reduces the performance impact of `SessionMiddleware` on routes that do not leverage sessions. [#207]
