+== Migrating from Gun 2.0 to 2.1
+
+Gun 2.1 contains a small security improvement for
+the HTTP/2 protocol, as well as includes a small
+number of fixes and improvements.
+
+Gun 2.1 requires Erlang/OTP 22.0 or greater.
+
+=== Features added
+
+* A new HTTP/2 option `max_fragmented_header_block_size` has
+ been added to limit the size of header blocks that are
+ sent over multiple HEADERS and CONTINUATION frames.
+
+* Update Cowlib to 2.13.0.
+
+=== Bugs fixed
+
+* Gun will no longer configure the NPN TLS extension,
+ which has long been replaced by ALPN. NPN is not
+ compatible with TLS 1.3.
+
+* Gun will no longer crash when TLS connections close
+ very early in the connection's life time.
