+## Cross-System LLM Budget Coordination
+
+PRAutoBlogger and Peptide News both call OpenRouter and may share a single API key / billing account. Their combined spend should be considered when setting per-plugin budgets.
+
+| Plugin | Default Models | Typical Daily Spend | Budget Control |
+|--------|---------------|--------------------:|----------------|
+| PRAutoBlogger | Gemini 2.5 Flash Lite (analysis + editing), Claude Sonnet 4 (writing) | $0.05–$0.30 depending on article count | Hard-stop monthly budget in plugin settings |
+| Peptide News | Google Gemini 2.0 Flash (keywords + summaries) | $0.01–$0.05 | No hard budget yet (planned) |
+
+**Important:** If your OpenRouter account has a global spending limit, set each plugin's budget to less than half the total. PRAutoBlogger will hard-stop when its budget is exhausted, but Peptide News currently has no budget enforcement — a spike in news fetches could consume shared quota.
+
+**Future improvement:** A shared `wp_options` key (e.g., `ecosystem_monthly_llm_budget`) that both plugins read, with each plugin reserving its allocation on startup. This requires coordination at the ecosystem level and is tracked as a medium-term goal.

+## [0.2.1] — 2026-04-12
+
+### Changed
+- **Reddit data source switched to RSS primary, .json fallback.**
+  PullPush.io was frequently stale/unavailable. Reddit RSS/Atom feeds work
+  reliably from datacenter IPs (Hostinger) where .json gets 403. Comments
+  are still fetched via .json (unavailable in RSS).
+- Updated "Enabled Sources" checkbox label to "Reddit (RSS + .json)".
+- Updated "Test Connections" to show RSS + .json status.
+- Source status indicator now shows Reddit RSS (Primary) and .json (Fallback).
+
+### Removed
+- `class-pull-push-client.php` — replaced by RSS feeds in `class-reddit-json-client.php`.
+- All PullPush.io references from admin UI, docs, and provider code.
+
+### Fixed
+- Generate Now button now always sends `force: '1'` to clear stale generation locks.
+- Fixed encryption double-encryption bug with `enc:` prefix detection.
+
+## [0.2.0] — 2026-04-12
+
+### Changed

+  and require no authentication.
+- Removed Reddit Client ID and Client Secret fields from admin API Keys tab.
+- Updated "Test Connections" results to show Reddit source status.
+
+### Added
+- Source status indicator in API Keys tab showing RSS and .json
+  availability with live status dots and last-collection timestamp.
