+* Add Chromium-based Edge support. This involves adding a new Chromium driver to
+ the tree too.
+* Extra domains added for CDP: Network, Performance, Security, Target
+* Firefox: enable full page screenshots
+* Better support for Java 9+ modules
+* Start reworking HTTP abstractions. These should better support streaming, and
+ so will not require us to hold all requests in memory.
