First stable release of Keyv v6, published to npm's latest tag.

All 20 published packages release in lockstep at 6.1.0; there is no 6.0.0. @keyv/website is private and not published.

Coming from v5? Follow the v5 to v6 migration guide, or point your coding agent at https://keyv.org/skills/migrate. v5 stays in maintenance; install it with keyv@5.

These are changes since 6.0.0-rc.1. Coming from v5, start with the migration guide.

Promote 6.0 to release candidate: Cloudflare KV adapter, MySQL fixes, and a full dependency refresh.

All published @keyv/* adapters release in lockstep at this version. @keyv/website is private and not published.

• mysql: keys are now stored as VARBINARY (6e519b4, #2015; f579073, #2016) Migration: @keyv/mysql tables created under 6.0.0-beta.4 use the previous key column type. Recreate the keyv table, or ALTER the key column to VARBINARY, before upgrading.

Finalize the v6 storage-adapter API (ttl → expires) and complete the cross-adapter code/test review.

• Storage adapters now use expires (absolute epoch-ms timestamp) instead of a relative ttl. (da9c08f, #1981) Migration: if you call a storage adapter directly or implement a custom one, read the absolute expires value from the entry envelope instead of accepting a ttl argument. The Keyv core API is unchanged — it continues to derive expires from the value envelope, so typical...

This release rolls up the entire v6 beta cycle — everything merged since v6.0.0-alpha.3. v6 is a major, ground-up modernization of Keyv: a leaner core, a new raw-data API, first-class capability detection, telemetry, two new encryption packages, a dependency-free etcd adapter, and a wave of breaking dependency upgrades across the monorepo.

Heads up: v6 contains a number of breaking changes vs. v5. If you are upgrading from v5, read the v5 → v6 migration guide alongside these...
