What’s new in Gutenberg? (2 September)

The big focuses throughout this release cycle were full site editing (FSE) and the widgets screen. On the FSE front, multiple FSE blocks were implemented and are now available for testing in the FSE experience (“Site Editor”). With regards to the widgets screen, more details are shared below.
Aside from these two focuses, GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ 8.9 contains some small new features, multiple bugbug A bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority. fixes, and some performance improvements.

Widgets moved out of experiments

One of the objectives of WordPress 5.6 is to allow using blocks in widgetWidget A WordPress Widget is a small block that performs a specific function. You can add these widgets in sidebars also known as widget-ready areas on your web page. WordPress widgets were originally created to provide a simple and easy-to-use way of giving design and structure control of the WordPress theme to the user. areas. This is a complex task, and for now there is no decision on whether the new screen should be available for all users or a subset of users. Your feedback may help weigh the options.

In Gutenberg 8.9, the blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience.-based widgets screen is enabled by default and replaces the default WordPress widgets screen. Themes and plugins are able to opt out of this screen by calling remove_theme_support( 'widgets-block-editor' ) or by using the gutenberg_use_widgets_block_editor filter respectively.

Your testing, feedback, and insights are very useful to inform the direction of the next iterations. If you come across any bugs, please submit a new issue in the Github repository.

Performance Benchmark

Gradual changes in the editor have made its rendering pipeline more asynchronous. As a result, the usual metrics (loading time, typing time) that we collect in the performance benchmarks may have not always represented the performance gains and losses experienced by some users.

We are improving the way times are measured to account for the more async nature of the editor rendering. We will update this post with performance results once we are confident that they accurately measure the performance of the editor.

The synchronicity changes in question only affect Gutenberg 8.8 and 8.9.
The numbers shared for previous releases are still an accurate way of measuring the editor’s performance.
