# Bespin 0.5 Release Notes

Up - Next Release

## Known Bugs

This release is a preview release. We wanted to get this out to embedders so that they could try it out and give us feedback on the new packaging.

- The editor may be invisible or behave strangely if it does not have a height assigned to it. bug 517809
- The scrollbar behavior is not yet back to its old state, so you may witness odd appearance or behavior. A future release will break the editor gutter area out into a separate component, which will make fixing the scrollbars easier. bug 527809
- The BespinEmbedded.js file is larger than we'd like it to be, but optimizing its size is not easy at this stage. We'll be looking at ways to shrink it further from release to release. bug 528479
- Currently, Bespin is putting three objects into your page's global namespace: SC, ENV and tiki. bug 528480
- In development, the SproutCore test runner is not yet working, likely due to the new "Tiki" module loader that Bespin is using. bug 528482

## Features

- The user-facing API is now simpler for embedding, and it's possible to use the editor without writing any JavaScript code.
- New documentation and documentation toolchain

## Infrastructure

- SproutCore now provides the underlying GUI toolkit
- The code has been completely reorganized into CommonJS modules
- Dojo is no longer required
- The scrollbars are no longer built directly into the editor component, but are instead separate components that can be changed or reused.
- Bespin Embedded is built using the SproutCore build tools (and therefore depends on Ruby, various gems and SC code to build)

## Other Changes

- JSON files are now run through the JavaScript syntax highlighter
- Multiline strings in JavaScript are now highlighted correctly (bug 524577). Thanks to Irakli Gozalishvili.
- Scrollbars are drawn a little nicer with respect to their antialiased position.
