## Changelog

### \[1.1.0] - 2026-08-31

#### Security and correctness

- Removed browser fingerprinting, WebDriver-suppression flags, and Medium's internal GraphQL endpoint.
- Replaced private-endpoint extraction with bounded DOM reads from the public following page.
- Added strict input validation, truthful provenance fields, exact output-schema validation, and automated tests.

### \[3.0.0] - 2026-05-22

#### Changed

- Increased scroll attempts from `ceil(maxItems/10)+3` → `ceil(maxItems/5)+5` for each user profile
- Increased scroll wait from 2s → 3s to give Medium more time to lazy-load cards
- Increased `maxConcurrency` from 3 → 5 for parallel multi-user scraping
- Only stop early on empty scrolls after at least 3 attempts (avoids premature exit)

All notable changes to the Medium Following Scraper are documented here.

### \[1.1.0] - 2026-05-21

#### Added

- **Multiple usernames support**: New `usernames` array input — scrape following lists for multiple users in one run.
- **Parallel processing**: Added `maxConcurrency: 3` to PlaywrightCrawler.
- Input schema updated with `usernames` (stringList) field.
- Fixed final log to correctly report `state.totalScraped`.
