0.3.0-alpha.1 - 2026-06-11
Alpha iteration: resync the published SDK with the latest dev (sub-plan 27.1 security-hardening release). No breaking API changes.
-
webhooks.verifyfailure codes are now dotted (webhook.*prefix). Every code in theWebhookSignatureErrorCodeunion changed:signature_missing→webhook.signature_missingsignature_malformed→webhook.signature_malformedtimestamp_missing→webhook.timestamp_missingtimestamp_outside_window→webhook.timestamp_outside_windowsignature_mismatch→webhook.signature_mismatch
Consumers branching on
result.codeneed to add thewebhook.prefix. The new format matches the openapi error-code convention and is now byte-equivalent across the Node, Python, Go, Ruby, and JVM SDKs (sub-plan 21.3 row C-8).
- Two new failure modes, split out for better diagnostics:
webhook.secret_missing- the caller passedsecret: ''(previously collapsed intosignature_mismatchvia HMAC-of-empty-key).webhook.timestamp_invalid- thet=value parsed but was non-finite / non-positive (previously collapsed intotimestamp_missing).

0.1.0-alpha.2 - 2026-05-29
First release published from the public mirror repo
(tosh-labs/blockchain0x-node) via npm Trusted Publisher OIDC with
Sigstore provenance attestation. Functionally identical to
0.1.0-alpha.1; this version validates the two-stage release pipeline
(private monorepo -> mirror to public repo -> publish from public repo
with provenance).
package.jsonnow declares@types/nodein devDependencies so a standalonenpm installoutside the monorepo resolves cleanly. This was implicit (hoisted) in the monorepo build but explicit here for the public-repo build path.
0.1.0-alpha.1 - 2026-05-29
Published from the private monorepo via npm Trusted Publisher OIDC,
WITHOUT provenance attestation (npm requires the source repo to be
public for --provenance and blockchain0x-app is private).
Functionally identical to 0.1.0-alpha.0; this version validated the
CI publish wire and ships the LICENSE + CHANGELOG files alongside the
tarball.
LICENSEfile (Apache-2.0) now ships in the tarball.CHANGELOG.mdfile shipping in the tarball.
0.1.0-alpha.0 - 2026-05-29
Initial alpha publish. Manual release via the committed
scripts/publish.sh helper.
