+
+## Features
+
+### `:oauth` plugin
+
+The `:oauth` plugin manages the handling of a given OAuth session, in that it ships with convenience methods to generate a new access token, which it then injects in all requests.
+
+More info under https://honeyryderchuck.gitlab.io/httpx/wiki/OAuth
+
+### session callbacks
+
+HTTP request/response lifecycle events have now the ability of being intercepted via public API callback methods:
+
+```ruby
+HTTPX.on_request_completed do |request|
+  puts "request to #{request.uri} sent"
+end.get(...)
+```
+
+More info under https://honeyryderchuck.gitlab.io/httpx/wiki/Events to know which events and callback methods are supported.
+
+### `:circuit_breaker` plugin `on_circuit_open` callback
+
+A callback has been introduced for the `:circuit_breaker` plugin, which is triggered when a circuit is opened.
+
+```ruby
+http = HTTPX.plugin(:circuit_breaker).on_circuit_open do |req|
+  puts "circuit opened for #{req.uri}"
+end
+http.get(...)
+```
+
+## Improvements
+
+Several `:response_cache` features have been improved:
+
+* `:response_cache` plugin: response cache store has been made thread-safe.
+* cached response sharing across threads is made safer, as stringio/tempfile instances are copied instead of shared (without copying the underling string/file).
+* stale cached responses are eliminate on cache store lookup/store operations.
+* already closed responses are evicted from the cache store.
+* fallback for lack of compatible response "date" header has been fixed to return a `Time` object.
+
+## Bugfixes
+
+* Ability to recover from errors happening during response chunk processing (required for overriding behaviour and response chunk callbacks); error bubbling up will result in the connection being closed.
+* Happy eyeballs support for multi-homed early-resolved domain names (such as `localhost` under `/etc/hosts`) was broken, as it would try the first given IP; so, if given `::1` and connection would fail, it wouldn't try `127.0.0.1`, which would have succeeded.
+* `:digest_authentication` plugin was removing the "algorithm" header on `-sess` declared algorithms, which is required for HTTP digest auth negotiation.
