Changelog

Shipped this week.

Releases, fixes and performance wins. No marketing, no breadcrumbs — just what changed and when.

v64.3.0 Apr 17, 2026
Zero‑copy response streams
  • New Stream Response bodies from KV reads without a single allocation. Benchmarked at −38% CPU on large blobs.
  • Perf Request router rewritten in WASM. Cold boot median drops from 0.9ms → 0.6ms.
  • Fix 64 logs --follow no longer drops frames under heavy traffic.
v64.2.1 Apr 04, 2026
Mesh‑wide KV replication
  • New KV writes now replicate to all 12 edge regions with a single RTT. Eventual consistency window: ~80ms p99.
  • New Atomic counters: kv.incr(key, n) and kv.decr(key, n).
  • Perf Idle‑to‑first‑request median: 0.4ms, down from 0.7ms.
v64.2.0 Mar 21, 2026
Structured concurrency, by default
  • Breaking Child fetches inherit the request's deadline. Dangling promises no longer keep workers alive.
  • New request.deadline and request.signal are first‑class and always non‑null.
  • Fix Deploys with a node_modules larger than 256MB now fail loudly instead of silently hanging.
v64.1.4 Mar 02, 2026
Friendlier CLI errors
  • New Every CLI error includes a short, copy‑pasteable fix. No more "segfault: see dmesg".
  • Fix 64 rollback now actually rolls back when the previous revision is more than 30 days old.
v64.1.0 Feb 10, 2026
Public beta
  • New 64bit.site opens to the public. Free tier: 1M requests, 1GB KV, unlimited subdomains on *.64bit.site.
  • New First three public projects ship: mkpgc, kv, golfklub.
v64.0.0 Jan 01, 2026
Hello, 64
  • New The first cut of the 64‑bit runtime. Typed, deterministic, and quieter than it has any right to be.
