+# 0.6.4
+
+This release takes where the last left off, and makes a concerted effort to improve both the test coverage and the number of features for which there are functional tests.
+
+## Improvements
+
+* Running Ruby 2.7 with no warnings;
+
+* Test suite now has functional tests for:
+  * authentication on proxies (http, socks4a, socks5);
+  * DNS-over-HTTPS;
+  * connect timeouts (still a bit flaky though);
+
+* Improved test coverage of project to 90%;
+
+* building website/blog with Jekyll 4;
+
+## Bugfixes
+
+* fixed regressions on HTTP, SOCKS4a and SOCKS5 proxy authentication;
+* fixed DNS-over-HTTPS implementation to be compliant with the latest RFC;
