0.5.2

Release notes for 0.5.2.

Released: 2026-09-08

Features

• Header actions now carry a stable data-zdtp-action attribute on both affordances — the inline header link and the compact kebab popover — with the ids export, import, apply, and reset. The ids are stable across releases; the display labels are not. This gives consumer tests a selector that survives a label change, which is what broke in #831. The hook removes the dependence on the label; it does not remove the responsive collapse, so a locator still needs to be visibility-qualified and panel-scoped — see the recipe Reaching header actions and PORTABLE-CONTRACT.md §7.6. (91916b4, #840)

Fixed

• The popover action items and the header region items are now keyed by their stable action id rather than by their display label. Two actions sharing a label previously produced duplicate keys, so reconciliation could reuse the wrong node and leave an item with a stale handler or aria-disabled state. (c3384ae)

• The 0.5.1 changelog said the old header-action selector "worked through 0.4.14". It worked through 0.5.0 — v0.4.15 and v0.5.0 both shipped before the collapse landed. (c3384ae)

Other Changes

• The documentation site moved to https://zdtp.zudolab.dev/, and the playground and minimal example to https://zdtp-playground.zudolab.dev/ and https://zdtp-minimal.zudolab.dev/. The package homepage field follows. (0b9e596, ef41bf2, #835)

• The 0.5.1 release notes now flag the header-action collapse as consumer-affecting, with the exact 1135px container-query threshold and the fact that it measures the shell's content-box inline size rather than the viewport. (6215888, #841)

• New bilingual recipe, Reaching header actions, covering both a label-based pattern for existing releases and the id-based pattern from this one. (c701369, #842)

• Twenty dead *.pages.dev example-demo links on the Examples page were repointed to their live zudolab.dev hosts. (c83ffa3, #836)
