Incompatibilities and deprecations
Support for Word conversion/publication has been removed.
Support for HareScript code in the WebHare filesystem (publisher) and in published output has been removed.
The webserver will only run HareScript code from a module folder, not from output/ or storage/ folders
site:: and currentsite:: loadlib paths are no longer supported
ajvformats has been upgraded to 3.0.0. This has some effects on OpenAPI specifications:
Formats time and date-time now require timezone, as per JSON Schema specification / RFC3339.
Added formats iso-time and iso-date-time that have optional timezone, they can be used for backwards compatibility.
Keywords formatMaximum and formatMinimum for time and date-time format now take into account timezone (both for time and for date), the previous comparison logic that ignored timezone is preserved for iso-time and iso-date-time formats.
