Recent updates
v1.0.3
Release v1.0.3 has no release notes. The code diff indicates this version mainly changes build and packaging configuration, including a TypeScript toolchain upgrade and a shift in the generated JavaScript target from ES5 to ES2015, along with changes to what gets published to npm.
v1.0.2
This release (v1.0.2) contains essentially no code-level behavioral changes. The diff shows a package version bump and the addition of a package-lock.json file for dependency locking.
v1.0.1
Release v1.0.1 was published on 2019-05-26, but the publisher did not provide any release notes. No documented new features, fixes, breaking changes, or dependency updates are available from the provided release data, so developer-impact risk cannot be assessed from release notes alone.
v1.0.0
v1.0.0 has no publisher release notes provided, but the code diff shows a substantial internal rewrite from JavaScript to TypeScript with the compiled output moved to a dist/ entrypoint. The Tracer stream implementation was refactored and the public method signatures for event creation were narrowed, along with package build/publishing configuration changes.
v0.1.3
Release v0.1.3 includes no provided release notes. The only observed code change is in package.json, where the version is bumped and a license field is added.
v0.1.2
Release v0.1.2 contains no provided release notes. Based on the diff, changes appear limited to README documentation and package metadata, with no lib/source code changes shown in the provided diff.
v0.1.1
Release v0.1.1 contains no published release notes. The diff shows only CI and package metadata changes, with no library source code modifications.
v0.1.0
Release v0.1.0 contains a major rewrite of this library’s public API and internals. The repository’s release notes are effectively empty, so the changes visible in the code and documentation updates represent undocumented behavioral and compatibility shifts.
1.3.0
The provided release notes are missing (none were included by the publisher). The code changes for version 1.3.0 are small but introduce new BunyanTracer behavior around parent/child tracing and field initialization.
1.2.0
Release 1.2.0 was published on 2015-02-20, but the publisher provided no release notes. As a result, there is no documented information here about new features, bug fixes, breaking changes, or security updates.
