What's new in this version:

- This patch addresses a regression found in 2021.2.0 where users were unable to make requests against localhost on certain platforms like Windows and through local DNS servers across all platforms.
- Once discovered we removed 2021.2.0 from the auto-update list and began our investigation. Through investigation we found the source of the regression was an update made to node-libcurl and worked with the maintainer to get a new build that resolves the issue.
