# Changelog

All notable changes to PRAutoBlogger will be documented in this file.

Format follows [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project uses [Semantic Versioning](https://semver.org/).

## [0.2.0] — 2026-04-12

### Changed
- **Reddit data source migrated from OAuth to PullPush.io + .json fallback.**
  Reddit rejected our API application; PullPush.io is free, requires no auth,
  and provides better subreddit-wide comment search. Reddit .json endpoints
  serve as an automatic fallback when PullPush is down.
- Removed Reddit Client ID and Client Secret fields from admin API Keys tab.
- Updated "Test Connections" results to show which Reddit source is active
  (PullPush.io or .json fallback) instead of generic "Reddit API connected."
- Updated "Enabled Sources" checkbox label from "Reddit" to "Reddit (via PullPush.io)".

### Added
- Source status indicator in API Keys tab showing PullPush.io and Reddit .json
  availability with live status dots and last-collection timestamp.
- Configurable research cache TTL (1–72 hours) in Sources tab.
- Reddit time window selector (24h / week / month) in Sources tab.
- Posts-per-subreddit limit (5–100) in Sources tab.
- LiteSpeed cache purge step in CI/CD deploy pipeline.

### Removed
- `class-reddit-api-client.php` — replaced by `class-pull-push-client.php`
  and `class-reddit-json-client.php`.
- Reddit OAuth credential fields and encrypted storage entry.

### Fixed
- Deploy pipeline now purges LiteSpeed/OPcache after file extraction,
  preventing stale PHP bytecode from being served.
