Both pages to bisync don’t have the option --track-renames listed.
See rclone bisync and Bisync
In the top right corner of both pages is a label that indicates that these pages are for version 1.58.
However, under Limitations \https://rclone.org/commands/rclone_bisync/ and in the Changelog \https://rclone.org/bisync/#v1-66 the option is mentioned.
The option seems to have been added in 1.66 so it should be listed under \https://rclone.org/commands/rclone_bisync/#options and \https://rclone.org/bisync/#command-line-syntax
Actually, i am a little confused why it’s showing up in the docs at all if they are for v1.58.
PS: i corrupted the links because 'new users can only put 2 links in a post'.
