+### v0.9.0
+
+- Add connection progress indicator (@talex5 #220).  
+  Clients can now use `Capnp_rpc_unix.with_cap_exn` to show a progress indicator while waiting to connect.
+  It will use the log if enabled.
+  If not, but stderr is a tty, it shows a message while connecting and then erases it (if connecting takes longer than 0.5s).
+  If stderr is not a tty, it just prints a message there.
+
+- Use `Mirage_crypto_rng_lwt.initialize` instead of `Mirage_crypto_rng_unix.initialize` (@hannesm #217).  
+  The former periodically feeds entropy to the RNG, while the latter seeds the RNG only once.
+
+- Set TCP_KEEPIDLE=60 if possible (@talex5 #214).  
+  Cap'n Proto connections tend to be long lived and we therefore turn on the `SO_KEEPALIVE` option.
+  However, the default keepalive timeout of 2 hours is much too long for some networks.
+  In particular, Docker's libnetwork silently drops idle connections after about 10 minutes.
+
+Windows support:
+
+- Prevent crash if ExtUnix wasn't built with sockopt (@MisterDA #218).  
+  If ExtUnix isn't built with sockopt then the symbol `have_sockopt_int` isn't available and an exception is raised. 
+  This may be the case on some environments (e.g., ExtUnix built with mingw-w64).
+  It is a workaround until support for `TCP_KEEPIDLE` is added for these environments (e.g., using Winsock instead).
+
+- There is no SIGPIPE on Windows (@dra27 #212).
+
+- Switch from "capnpc" to "capnp compile" (@talex5 #213).  
+  `capnpc` seems to be the old name, and isn't present on Windows.
+
+Build changes:
+
+- Remove Travis and Dockerfile (@talex5 #220).  
+  Travis is very slow and error-prone now, and ocaml-ci generates a working Dockerfile automatically for people who want it.
+
+- Include transitive dependencies in opam files (@talex5 #219).  
+  Patch generated by https://github.com/ocurrent/opam-dune-lint/
+
+- Require `tcpip.unix` specifically to get the checksum stubs linked (@hannesm #216).
