Notable changes: - `uv_ip_name()` has been added. - On Windows, `uv_fs_read()` and `uv_fs_write()` now return `UV_EBADF` instead of `UV_EPERM` when the file descriptor was opened with incorrect flags. This matches the behavior on other platforms. - Streams can be reset and attempted to read from after EOF is read. - The main thread now has a valid ID instead of `NULL`. - `uv_cpu_info()` now supports `aarch64`. - Several minor issues related to mingw32 have been fixed.
