# Release 788 - July 2026

# New features

Product definitions now support line exclusion through a new Not valid on lines field in the Concession section on the Product Definition page. This makes it possible to configure tickets that are valid on regular bus, tram, or metro services, but not on specific lines (for example night lines).
Line exclusion is enforced throughout TapConnect:
- Validation rejects taps on excluded lines.
- Travel rights do not activate when a passenger taps on an excluded line.
When both inclusion and exclusion are configured, exclusion takes precedence: a line listed under Not valid on lines is never accepted, even if it also appears under Valid on lines.
The same line number cannot appear in both Valid on lines and Not valid on lines, so conflicting product definitions are caught before save.
Products with Not valid on lines configured cannot be used as building blocks in Combi Products.
The Customer Service ticket view shows excluded line numbers when a ticket has line-based restrictions.
Version 8 of the Issuing API is now available. Product and ticket info endpoints include validOnLineIds and notValidOnLineIds.
