     - new permalinking experience: `/b` is now a _redirect_ to the target page, anchored on the branch, rather than a 200 OK serving you the target page but aliased.
 
+        % id = "01JHXX4CDTS0DWGFM8TAN24TAY"
         + the permalink button on the right now copies the permalink to your clipboard directly, because navigating to the permalink only to be redirected to a non-permanent link would be pretty useless.

     - subpage listings are now generated automatically.
 
+        % id = "01JHXX4CDT1ZWQ70DJXACECTDQ"
         - this changes the inner structure of major categories a bit.
         nesting has been reduced and there's only a flat list of pages under each individual category.

         - in the future, I'd like to incorporate a fuzzy search & tagging system to make it a bit easier to find posts.
         maybe I'll also rewrite Atom feeds to be based off of this.

     - branch dates are now rendered server-side to prevent layout shifting on load.
 
+        % id = "01JHXX4CDT7A7YFS5KXJVRQTCP"
         - because of this, dates now use `YYYY-MM-DD` format consistently in all locales.

         - despite this, the dates are still corrected on the client side to account for time zone differences.

     + the treehouse will now scale more nicely with your font size preferences, as you've set them in your browser.

     - internals: branches are now based on flexboxes rather than background images.
     this requires sending a bit more HTML, but [the layout is a lot more stable][branch:01HP20D2R4F2XZVBBQNVW6CVHE] as well as being [easier to extend][branch:01HP20D2R4C0DZAKKB84FCQNXN]
