Overview - Factagora

What is a Changelog?

The changelog tracks notable changes to Factagora products, split into two independent release tracks:

API — the Factagora API, for developers integrating against it
Extension — the DeepVerify Chrome extension, for end users

Each track has its own version numbers and its own release list, so an API release and an Extension release with the same version number are unrelated changes.

API Versioning

The API follows Semantic Versioning: MAJOR.MINOR.PATCH.

Part	When to increment	Examples
MAJOR	Breaking changes: existing client code will break	Removing a field, renaming an endpoint, changing auth method
MINOR	New features, backwards-compatible	New endpoint, new optional parameter, new response field
PATCH	Bug fixes, backwards-compatible	Fixing incorrect response data, performance improvements

Versions in the 0.y.z range are considered early development, so anything may change. Stability is guaranteed from 1.0.0 onwards. Only changes to the publicly documented APIs are recorded here. Internal endpoints are excluded.

Extension Versioning

The DeepVerify Chrome extension is versioned by its manifest.json version and auto-updates for all users, so there’s no compatibility concern to call out — releases just describe what changed.

What Gets Recorded (API)

Changes to the following endpoints are tracked in the API changelog:

Endpoint	Description
`GET /api/v1/fact-search`	Fact Search
`POST /api/v1/fact-checker`	Fact Checker

`POST /api/v1/fingerprint/embed`	DeepStamp Embed

Change Categories

Each release groups changes into the following categories:

Category	Meaning
`Added`	New feature or endpoint
`Changed`	Change to existing behavior
`Deprecated`	Feature that will be removed in a future version
`Removed`	Feature that has been removed
`Fixed`	Bug fix
