The author's decision of 7 October 2026. A release saved next to a capsule
cannot exist when the capsule is made, and once the date comes the capsule
can be opened: such a file only opens it again and does not cover the real
case, someone opening it decades later when drand is gone and nobody saved
anything. Long-term recovery rests instead on archives and cache services
that keep the releases of all rounds; a reader asks for its round and
verifies the signature against the pinned key.
Spec: the .dkr extension (section 20, back to v0.14), sections 1, 4, 8, 45,
47.1, 49, 50 (rewritten), 53, 62.1 (rule 28 removed, rule 26 reworded),
63, 70, 73, 74 (the datekeys.release .dkk extension dropped too), 76
(the v0.15 block, with the discarded design) and the annex 79. The
release object, the chain hash at step 10, step 9.c option B and the
archive format stay.
Code: decrypt -save-release and the command datekeys release are gone,
with writeRelease and their tests; decrypt -release FILE stays. The
release objects of testdata/releases are now <round>.cbor, and
TestVectorFilesAreCurrent fails on a file the generator no longer writes.
