5.8.0

Release notes for 5.8.0.

Released: 2026-08-20

Features

• Added strict anchor validation to the showcase and generated-project link checkers, including source-first validation for scaffolded sites. (b50bd9aac, 59127e7fe)

• Added a published-version guard that prevents release scaffolds from pinning first-party packages that are not yet available from npm. (4bdc37132, 8c234c08e)

• Shipped a complete nav-overflow regeneration path with ejected headers, preserving stable CSP bytes while allowing local nav behavior and class-token customization. (1b3d501c3, 721ff37d3)

Bug Fixes

• Made nested island props preservation explicit with data-zd-props-preserve, preventing opted-out islands from receiving props updates or remount flags during client navigation. (e75cff084)

Other Changes

• Strengthened docTags regression coverage so an unselected feature cannot emit either a true or false config field. (37dec787c)

• Updated @takazudo/zdtp to 0.4.12 across the package, showcase, and generated scaffold.
