This new release is largely focused on bug fixing and optimising various parts of the apps. There's about 26 improvements and 25 bugs and security fixes included - as always many of these apply to both the mobile and desktop app (see the [desktop changelog](https://joplinapp.org/help/about/changelog/desktop) and [mobile changelog](https://joplinapp.org/help/about/changelog/android/)).
Since version 2.6 it was possible to assign an emoji icon to a notebook, and with this new version it's now possible to assign any custom icon. The icon may be a PNG or JPG file of any size. The app will then import the file and resize it to the correct size. To use a custom icon, follow these steps:
This version also includes a number of improvements to the plugin API, in particular it is now easier to customise the editor context menu from a plugin and dynamically add items to it depending on the context. For example, with the Rich Markdown plugin it will be possible to right-click on an image and open it, or copy it to the clipboard.
A few additional functions have also been added to make plugin development simpler - in particular a command to open any item, whether it's a notebook, note, tag or attachement; and functions to work with attachements, in particular to reveal an attachement in the system file explorer, and to track changes to an attachement.
