-## 1.0.0 Breaking Changes
-
-pdfjs 1.0.0-alpha.1 (still in development; expected to be buggy) contains a rewritten layout engine (layout engine of pdfjs `<=0.5` reached its limits), i.e., both API and layout behavior has changed completely. Install with:
-
 ```bash
-npm install pdfjs@1.0.0-alpha.1
+npm install rkusa/pdfjs@2.0.0-alpha.1
 ```
 
+## 2.0.0 Breaking Changes
+
+Version `2.0.0` is a re-write. I tried completely different approaches of the last years. Finally, this version has streaming layouting with smart content chunking, which allows for having a small memory footprint even when creating a PDF document with thousands of pages. I highly expect to settle with this implementation.
+
+----------------
+
 ### Features
 
-- Text (many formatting options)
+- Text (with common formatting options)
 - Images (JPEGs, other **PDFs**)
-- Tables (fixed layout, header row, before page break rows)
+- Tables (fixed layout, header row)
 - Header & Footer
-- TTF Font embedding (as CID fonts, i.e., support for fonts with large character sets)
+- AFM fonts && OTF font embedding (as CID fonts, i.e., support for fonts with large character sets)
+- Add existing PDFs (merge them or add them as page templates)
 
-**Missing:** AFM fonts are currently not implemented.

 If you are missing a feature, feel free to submit a PR or to ask for it.
