# Changelog

***

title: "Changelog"
description: "Latest updates and improvements to the ParseTx API."

## v1.0.0-rc8 - Pre-Launch Hardening & IP-Level Safety (June 2026)

\* **IP-Level Email Rate Limiting**: Added strict IP-based rate limiting (20/hour) across signups and magic links to protect Resend and domain reputation from abuse.
\* **Accessibility Indicators**: Standardized `:focus-visible` focus rings site-wide for complete WCAG keyboard navigation compliance.
\* **Success Page Key Recovery**: Refined success validation queries to gracefully display a key recovery card on page refresh rather than returning verification errors.

## v1.0.0-rc7 - Async Queue Limits & Lazy Resets (June 2026)

\* **Queue Consumer Limit Enforcement**: Implemented limits in the background worker to skip processing for deactivated keys or keys that exceeded their daily safety token budget.
\* **Lazy resets for background clients**: Automated daily and monthly usage resets for keys running asynchronously.

## v1.0.0-rc6 - RapidAPI Gateway Auth Bypass (June 2026)

\* **RapidAPI Support**: Added verified proxy authentication support allowing RapidAPI to handle pricing and quotas while logging telemetry metrics without double-billing.

## v1.0.0-rc5 - Bearer Auth & Provisioning Backups (June 2026)

\* **Dual-Header API Authentication**: Upgraded all APIs and SDKs to support standard `Authorization: Bearer <key>` headers alongside `X-API-Key`.
\* **Backup key emails**: Automated email delivery of the raw API key at checkout to prevent user loss.
\* **Admin Route Rate Limiting**: Isolated internal administrative routes with strict IP-based lockouts.

## v1.0.0-rc4 - Tier-0 Fast Path & Webhooks (June 2026)

\* **Tier-0 Merchant Expansion**: We've expanded the in-memory deterministic fast-path cache to 587 top merchants. Long-tail targets were shifted to the KV cache, drastically optimizing Tier-0 hits and reducing latency.
\* **Website Documentation Sync**: Updated site-wide headers and footers to easily access the Docs, Contact, and API Quickstarts from any page.

## v1.0.0-rc3 - Free Tier & Pricing Updates (June 2026)

\* **Free Developer Tier**: Start free with 5,000 transactions/month and no credit card required. Claim your key via email verification at `/free-key`.
\* **Reduced Pricing**: Pay-as-you-go rate for the Developer tier reduced to a flat \$0.001/transaction (active after the free 5K transactions are exhausted).

## v0.1.0 - Private Beta Launch (June 2026)

\* **Initial Release**: The ParseTx API is now live.
\* **Batch Native**: Support for synchronous (≤10) and asynchronous (≤500) batches.
\* **PII Sanitization**: Implemented deterministic entropy trimming to remove UUIDs and card numbers before AI processing.
\* **SDKs**: Released official Node.js and Python SDKs.
