+Pico Default Theme Changelog
+============================
+
+**Note:** This changelog only provides technical information about the changes
+          introduced with a particular Pico version, and is meant to supplement
+          the actual code changes. The information in this changelog are often
+          insufficient to understand the implications of larger changes. Please
+          refer to both the UPGRADE and NEWS sections of the docs for more
+          details.
+
+### Version 2.0.0-beta.2
+Released: -
+
+```
+* [Fixed] Fix sliding animation of collapsible menu in IE 9
+* [Changed] Move Fontello font to `icon/` directory
+* [Changed] Improve Fontello font copyright notice
+* [Changed] Add Droid Sans and Droid Sans Mono font files to `font/` directory,
+            making Pico's default theme fully self-containing
+```
+
+### Version 2.0.0-beta.1
+Released: 2017-11-05
+
+**Note:** Pico's default theme was completely rewritten from scratch for
+          Pico 2.0 and moved to this separate repository. This changelog only
+          provides basic information about the most important changes compared
+          to Pico 1.0. It therefore doesn't include the changes made before
+          this release. The rewrite breaks backwards compatibility (BC).
+
+```
+* [New] Rewrite Pico's default theme from scratch with a much cleaner, more
+        modern, but still "stupidly simple" structure; the new theme officially
+        supports Internet Explorer 9+ as well as all versions of the major
+        desktop and mobile browsers, as long as they are still officially
+        supported by their respective vendor
+* [New] Pico's default theme is now a fully responsive theme, adapting the
+        layout to the viewing environment (desktops vs. tablets vs. smartphones
+        vs. ...)
+* [New] Add a collapsible page menu for small screens (menu slides up/down)
+* [New] Add basic form themeing
+* [New] Support a "widescreen" mode, demonstrating how themes can adjust their
+        behavior using config parameters (i.e. Pico's `config/config.yml`)
+* [Changed] Show top-level pages in the website's navigation only (i.e. show
+            `page.md` and `sub/index.md`, but not `sub/page.md`)
+* [Changed] Hide pages starting with a `_` in the website's navigation
+* [Changed] Move Pico's social icons from `index.md` to `_meta.md`,
+            demonstrating how themes can use YAML-only meta pages to support
+            dynamic content
