Removed

• Support for calling return (pipe) from vcl_recv has been removed after previously being deprecated. No action is required, save for awareness that rollbacks to older service versions containing calls to return(pipe) from vcl_recv will be blocked.

Changed

• The x-compress-hint header will now only be added on ESI requests if it was not previously set. This is a change from the previous behavior, which was to automatically append x-compress-hint to on for ESI requests. This change allows a VCL service to override the x-compress-hint set by ESI. Existing logic should continue to work as it does today, however any existing activated services that have been setting the x-compress-hint header before ESI will now find their logic overriding the automatic setting.

Added

• Documentation is now available for fastly.try_select_shield.

Fixed

• A bugfix has been made regarding workspace memory usage and std.count.
