 # Changelog
 
+## 2026-03-09 - 4.2.0 - feat(smartpdf)
+replace internal Express server with @push.rocks/smartserve, add PDF→WebP rendering, improve start/stop handling and bump dependencies
+
+- Replace internal Express HTTP implementation with @push.rocks/smartserve and update README wording to reflect HTTP server usage
+- Add PDF→WebP rendering: use pdf.js in-page rendering, capture canvases via Puppeteer to produce WebP buffers; added robust wait/timeout and error handling
+- Add start/stop guards: _isRunning flag, reset readiness Deferred on start, and throw if start called while running
+- Remove direct http/express exports from plugins and stop exporting express; export smartserve from plugins
+- Improve JPEG conversion to produce progressive JPEGs via SmartJimp (sharp mode)
+- Bump dependencies/devDependencies: @push.rocks/smartfs to ^1.5.0, add @push.rocks/smartserve ^2.0.1; devDeps @git.zone/tsbuild ^4.3.0, @git.zone/tstest ^3.3.0, @types/node ^25.3.5
+
 ## 2026-03-01 - 4.1.3 - fix(tests)
 use example.com in image conversion test and relax JPEG size assertion

+SmartPDF spins up a lightweight HTTP server (via `@push.rocks/smartserve`) bound to `localhost` and a headless Chromium browser. When you call a generation method:
 
 1. Your HTML is registered internally and served at `http://localhost:{port}/{id}`
 2. Puppeteer navigates to that URL, waits for the page to fully render, and captures a PDF
