+Release =v4.0.0= has been tagged.
+
+This release contains breaking changes.
+
+Minimum Go version required to use =go-vcr= is set to =1.22=.
+
+The import path for =recorder= and =cassette= packages has changed and now they
+reside in:
+
+- =gopkg.in/dnaeon/go-vcr.v4/pkg/cassette=
+- =gopkg.in/dnaeon/go-vcr.v4/pkg/recorder=
+
+Only version =2= of the cassette format is now supported.
+
+The =recorder.Options= struct has been removed. Instead of it, we can now use
+functional options to configure the recorder.
+
+The following =recorder.Option= functions may be used to configure the recorder.
+
+- =recorder.WithCassette= - sets the name of the cassette
+- =recorder.WithMode= - sets the mode of the recorder
+- =recorder.WithRealTransport= - sets the underlying transport used by =go-vcr=.
+- =recorder.WithBlockUnsafeMethods= - blocks unsafe methods, if set to =true=.
+- =recorder.WithSkipRequestLatency= - simulates request/response latency, if set to =true=.
+- =recorder.WithPassthrough= - configures passthrough handlers
+- =recorder.WithHook= - configures recorder hooks
+- =recorder.WithMatcher= - configures the matcher to be used
+- =recorder.WithReplayableInteractions= - allows interactions to be replayed multiple times, if set to =true=.
+
+The =cassette.OnRequestReplayFunc= type has been removed. Instead of it, users
+should use a =recorder.BeforeResponseReplayHook=.
+
+The =cassette.DefaultMatcher= is now stricter. See [[https://github.com/dnaeon/go-vcr/pull/98][#98]] and [[https://github.com/dnaeon/go-vcr/pull/99][#99]] for more details.
+
+Added support for blocking Unsafe HTTP Methods. The definition of Safe Methods
+comes from [[https://datatracker.ietf.org/doc/html/rfc9110#name-safe-methods][RFC 9110, section 9.2.1]]. See [[https://github.com/dnaeon/go-vcr/pull/100][#100]] for more details.
+
+Added support for server-side recording and replaying. See [[https://github.com/dnaeon/go-vcr/pull/101][#101]] for more
+details.
