How determine latest Kate syntax update number?

Last I found is https://kate-editor.org/syntax/update-5.256.xml
Before months was 5.240, I try 5.241, 5.242, 5.250. 5.260 - not found , next 5.257 etc
Is way to determine last number better than binary search of existing url? I am using syntax files in my editor.
5.240 and 5.256 are identical - they appear regularly and update depends from current date?

Is possible download index file Syntax Highlighting - Kate and parse it, but this way have not version numbers.
