- Previously, url.Parse did not enforce validation of hostnames within square brackets. - RFC 3986 stipulates that only IPv6 hostnames can be embedded within square brackets in a URL. - Now, the parsing logic should strictly enforce that only IPv6 hostnames can be resolved when in square brackets. IPv4, IPv4-mapped addresses and other input will be rejected. - Update url_test to add test cases that cover the above scenarios. Thanks to Enze Wang, Jingcheng Yang and Zehui Miao of Tsinghua University for reporting this issue.
