Changelog#

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

Unreleased#

1.0.0-beta.6 — Beta (2026-10-04)#

• Combine bounded Node request forwarding, experimental finite generated output

and UTF-8 transforms with the current helper/shared-stage Native compiler work. Size modes remain opt-in; no default optimization or target fallback changes.

• Add bounded opaque S3 getBody responses on Node Native/JavaScript and Fastly

Native, and embedded Assets bytes through the existing qualified interfaces. Fastly JavaScript S3 remains ineligible; arbitrary binary inspection is excluded.

• Qualify the explicit Node /server export for finite production HTTP, including

build identity, overload, readiness and graceful draining. Streaming/output/ transform/S3-body/blob-specific launcher qualification remains separate.

• Tighten Entities integration, JWT signing/verification and cleanup, and the

private MCP adapter. MCP remains unpublished and outside the 19-package set; Native signature-guest composition restrictions remain enforced.

• Require the separately selected installed-feature proofs and preserve exact

package/artifact identity. Fix guest JSON roundtrips while retaining ordered arrays and exact trust values; beta.5 historical guest-cache evidence remains distinct from current candidate cache reuse.

• Refresh example Wasm sizes from rebuilt default and experimental-size artifacts,

clarify bounded support limits, and preserve the reviewed npm latest tag.

• Retain the documented Viceroy missing-key CAS discrepancy as non-blocking by

release-owner direction. Raw failures remain recorded, CAS semantics are unchanged, and deployed Pulse cross-location acceptance remains separate.

1.0.0-beta.5 — Beta (2026-09-16)#

• Add bounded application-owned JSON decoding, pure application loops and string

trimming, execution-owned wall time, and exact-text SHA-256 digests.

• Preserve schema/KV parity, optional-property absence, JWT JavaScript support,

application error handling, bounded UTF-8 input and HTTP outcomes across the selected targets.

• Add provider-owned HTTP request deadlines and verify their exact packed

consumer closure, including cumulative effects and uncertain write outcomes.

• Preserve source-qualified effect identity and multifile composition through

exact installed packages.

• Bound Fastly Native string concatenation and avoid eager collection allocation

for scalar values, resolving large schema-encoding memory traps.

• Preserve bounded Fastly Native request headers and raise selected digest/S3

text capacity to 2 MiB.

• Share npm registry visibility polling across all release packages.
• Add a release-owner tagging helper with a dry-run default, clean-source and

remote-main checks, and immutable existing-tag handling.

1.0.0-beta.4 — Beta (2026-09-14)#

• Add ctx.encodeJson(value, 'schema.id') for schema-validated, bounded JSON text

before storage or other effects, across JavaScript and Native execution.

• Add manual release preparation that opens a draft PR, validates version

readiness before main, and leaves final tagged-source sealing to publication.

• Preserve published documentation and changelog history while advancing

current references during release preparation.

1.0.0-beta.3 — Beta (2026-09-14)#

• Fix CLI storage execution on Node Native, Node JavaScript and the Fastly Native local fixture host, including S3 response streams, bindings and conditional KV.
• Keep the last working Native application available when a development reload fails.
• Allow bounded npm registry propagation time and publish future releases directly under the latest npm tag while retaining the Beta release label.

1.0.0-beta.2 — Beta (2026-09-13)#

This candidate synchronizes the 19-package release catalog and prepares the next npm beta release:

• adds bounded S3-compatible object storage in @pulse-compute/s3, backed by

the Crypto hashing and signing primitives; the Assets contract stays intact;

• adds conditional KV operations and opaque generation tokens, with explicit

conflict handling and no non-atomic emulation;

• propagates explicit JavaScript targets through project analysis, retaining

resolved static third-party imports and ordinary awaited calls while checking Native eligibility independently;

• clarifies maintainer ownership, target boundaries, evidence requirements,

and human release authority;

• links public and internal package listings to npm and preserves the exact

published beta.1 documentation snapshot alongside the beta.2 documentation.

Conditional KV acceptance remains gated separately from the aggregate seal: Viceroy 0.21.0 creates a missing key for an existing-generation CAS, contrary to the required conflict behavior, and deployed Pulse cross-location acceptance is still pending. The standalone live Fastly probe confirms missing-key rejection but does not satisfy those Pulse acceptance gates. See wasm/test/kv/K4.md for the evidence and release boundary.

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.
