+* windows: Re-implement uv_fs_stat. The st_ctime field now contains the change
+  time, not the creation time, like on unix systems. st_dev, st_ino, st_blocks
+  and st_blksize are now also filled out. (Bert Belder)
+
+* linux: fix setsockopt(SO_REUSEPORT) error handling (Ben Noordhuis)
+
+* windows: report uv_process_t exit code correctly (Bert Belder)
+
+* windows: make uv_fs_chmod() report errors correctly (Bert Belder)
+
+* windows: make some more NT apis available for libuv's internal use (Bert
+  Belder)
+
+* windows: squelch some compiler warnings (Bert Belder)
