📝 Walkthrough

Walkthrough

Adds OEL release v26.2.20 documentation: new image tag rows (date 2026-06-19) for Hydra, Keto, Kratos, Oathkeeper, and Polis, plus corresponding changelog files. Kratos includes a substantive entry about notify_previous_addresses hook behavior; all other components receive empty-entry placeholders.

Poem

🐇 Hop, hop, a new tag appears,
26.2.20 joins the release frontier!
Kratos tells addresses old, "Hey, watch out!"
Keto and Polis have nothing to shout.
But every blank page is a promise kept—
The rabbit stamps docs while the changelog slept. ✉️
