v6.0.0-beta.4

Keyv v6.0.0-beta.4 — 2026-06-18

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

⚠ BREAKING CHANGES

• 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 keyv.set(key, value, ttl) usage is unaffected.

Features

• bigmap: wire up Hookified events — BigMap now emits SET, DELETE, and CLEAR via the new BigMapEvents enum. (b88d03f, #1977)

  import { BigMap, BigMapEvents } from '@keyv/bigmap';
  
  const map = new BigMap<string>();
  map.on(BigMapEvents.SET, (key, value) => console.log('set', key, value));
  map.on(BigMapEvents.DELETE, (key) => console.log('deleted', key));
  
  map.set('a', '1');  // → "set a 1"
  map.delete('a');    // → "deleted a"

  Also renames the exported MapInterfacee type to MapInterface (typo fix — safe within the v6 beta).
