Atom 1.19 Hackable Text Editor Improves Responsiveness and Memory Usage

It’s been almost two months since Atom 1.19 entered Beta stages of development, along with the promotion of Atom 1.18 to the stable channel, which introduced Git and GitHub integration straight into the heart of the editor, and the biggest new change is improvements to responsiveness and memory usage by implementing a native C++ text buffer. Atom 1.19 also comes with a full rewrite of text editor’s rendering layer, restores the ability for escape to return focus to center, optimizes the removal of trailing whitespace by using a native buffer search implementation, makes Atom respond better to actions, and adds support for rendering line number gutter without numbers when the “showLineNumbers” option is set to false.
