# 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;
