Changelog#

Pulse follows semantic versioning for public releases. The repository begins its public history with the 1.0.0-beta.1 prerelease.

1.0.0-beta.1 — Beta (2026-08-01)#

The first public Beta establishes a native-first Pulse application contract and completes the synchronized release candidate:

• promotes @pulse-compute/pulse into the synchronized public package set and

removes its duplicate Fastly-conditioned bootstrap so provider-specific startup remains owned by @pulse-compute/provider-fastly.

• adds --experimental-native-size to provider-neutral compile and Native

provider builds. The Native compiler owns the experimental size profile and the default remains unchanged.

• moves the fixed provider composition behind a neutral CLI facade. Concrete

host operations and target policy are now composed from provider-owned modules, while Node remains the reference/smoke substrate.

• adds synchronous string logging through ctx.log.error, warn, info, and

debug, including profile thresholds, Native pruning, a compact host ABI, provider-owned output, redaction, and four-mode conformance.

• completes direct Fastly JavaScript execution, provider capabilities, package

effects, local tooling, deterministic source/deployment packaging, and downstream runtime compilation.

• seals full-target-support availability for Node and Fastly JavaScript without

automatic fallback.

• adds revision-bound release reports, sixteen-shard evidence aggregation,

offline Fastly Native/JavaScript candidates, and exact binary-patch replay.

• adds the bounded Crypto, JWT, and Entities packages to the synchronized

18-package release catalog;

• synchronizes the Apache-2.0 package metadata, Beta documentation,

exact v1.0.0-beta.1 routes, and npm beta policy without assigning latest;

• performs no deployment or publication; those operations remain separately

authorized release actions.

• @pulse-compute/runtime as the canonical application surface;
• static Router authoring with parameters, mounts, terminal middleware, fallthrough, and error lanes;
• whole-project analysis with explicit effects and continuations;
• schema-backed request, fetch, and response handling;
• provider-neutral portable Wasm and direct native Fastly realization;
• Node development, inspection, testing, and provider conformance;
• package-owned GRIP and asset lowering;
• generated, versioned documentation and guarded release candidates;
• explicit runtime-target support gates with no automatic fallback.

The Beta deliberately rejects unsupported Native source instead of silently changing execution targets.
