Including a month’s worth of enhancements, Atom 1.23 comes with the ability for packages to register URI handler functions, which can be invoked whenever the user visits a URI that starts with “atom://package-name/,” and a new option to hide certain commands in the command palette when registering them via “atom.commands.add.” Atom 1.23 also improves the compatibility with external Git tools, as well as the performance of the editor by modifying the behavior of several APIs to no longer make callbacks more than once in a text buffer transaction. Along with Atom 1.23, GitHub also released Teletype 0.4.0, a tool that allows developers to collaborate simultaneously on multiple files.
