SFTP support for putty ppk v3

SFTP support for putty ppk v3

Although the new file format was introduced for Putty in version 0.75 (of 2021) there is still no support for the new V3 format in Xceed SFTP, requiring to convert files to the old format.

Are there any plans to upgrade this to the new version as 4 years have passed?
Anyone else waiting for an upgrade?
