Changelog

TurnitPass product updates

Recent platform changes across the humanizer, AI detector, writing tools, billing, and API.

Latest platform notes

Latest release

May 2026latest

Developer API expanded

Added authenticated v1 endpoints for humanize, paraphrase, rewrite, detect, citation, bibliography, and API key status.

GET/status

v1

API surface

Versioned v1 endpoints are tracked here when request shapes, limits, response fields, or authentication behavior change.

Tools

Writing workflow

Humanizer, AI detector, paraphrase, citation, and bibliography changes are grouped by practical writer impact.

Access

Billing and access

Secure checkout, workspace limits, API key behavior, and account access changes are called out separately.

Recent changes

02May 2026

Citation exports expanded

Citation and bibliography responses now include formatted HTML, plain text, BibTeX, and RIS output for common academic and technical styles.

03May 2026

Document import warnings surfaced

TXT, Markdown, DOCX, and PDF imports now keep source kind, filename, and parser warnings visible in writing and detector workflows.

04May 2026

Detector response normalized

Detector-style scans now return review estimates, source context, status, and writing-signal metadata through the same public API shape.

Versioning

v1 routes stay stable

Prompts

Sensitive implementation details stay internal

Billing

Billing keys remain configurable

How updates are organized

Release lanes

Changelog entries are grouped by user-visible behavior.

Internal implementation details stay private, but API contracts, workspace behavior, document import changes, and writing-tool surfaces are documented when they affect developers or writers.

Core

Humanizer and AI detector

Changes to AI-writing signal estimates, side-by-side review, and revision notes.

Research

Citation and bibliography

New source types, citation formats, BibTeX/RIS export behavior, and bibliography sorting logic.

API

Developer platform

API key lifecycle, limits, status fields, usage logging, and workspace controls.

Web

Public pages

Notion-style page updates, comparison pages, feature pages, pricing, contact, and localized shells.

Release policy

The changelog follows the same product boundary as the API platform: public notes cover endpoint behavior, billing surfaces, document parsing, and visible workflow changes. Sensitive prompt internals are handled as implementation details unless they affect public behavior.

Versioning
v1 routes stay stableBreaking API changes should ship under a new versioned route. Additive response fields may appear on existing v1 endpoints.
Prompts
Sensitive implementation details stay internalPublic notes describe behavior changes and compatibility impact, not internal prompts or private implementation details.
Billing
Billing keys remain configurableBilling, portal access, and plan limits remain configurable without exposing private setup details.
Documents
Parser changes are notedDocument import behavior for TXT, Markdown, DOCX, and PDF should be visible when it affects extracted text or warnings.

API compatibility notes

Existing API keys
Remain valid unless revokedKeys are stored as hashes and can keep calling v1 endpoints until a user revokes them or usage rules change.
Response fields
Additive by defaultClients should ignore unknown fields. Removing or renaming response fields requires a versioned change.
Word limits
Documented in referenceTransform endpoint and detection word limits are reflected in API reference and smoke coverage.

Changelog FAQ

Does the changelog include prompt changes?

Prompt internals are not published as full text because they are sensitive. Public notes describe behavioral changes, endpoint impact, and compatibility expectations.

How should API clients handle new response fields?

Treat unknown fields as additive metadata. Clients should parse the fields they need and ignore additional keys unless the API reference says otherwise.

Where do billing configuration changes appear?

Billing behavior is noted here when checkout, portal, or plan-limit logic changes. Production credentials are configured securely outside the codebase.
