On December 6, 2018 WordPress 5.0 “Bebo” has been released introducing its new block-based editor that is streamlined for the ultimate editing experience.
The new block-based editor won’t change the way any of your content looks to your visitors. What it will do is let you insert any type of multimedia in a snap and rearrange to your heart’s content. Each piece of content will be in its own block; a distinct wrapper for easy maneuvering. (source: https://wordpress.org/news/2018/12/bebo/)
Unfortunately, this new editing experience has a major flaw — a slow performance. In fact, slow performance as compared to the classic editor has been a commonly-reported issue. The WordPress 5.0.2 release scheduled on December 19, 2018 will bring major performance improvements to the editor, particularly for content that includes hundreds of blocks.
“The cumulated performance gains are around 330% faster for a post with 200 blocks. This might be even bigger for certain setups and plugin configurations — seeing the same test post be 540% faster with Yoast, for example.” Matias Ventura, WordPress
For those who prefer using the classic editor, support for the Classic Editor plugin will remain in WordPress through 2021. The Classic Editor plugin restores the previous WordPress editor and the Edit Post screen. Click to download the Classic Editor plugin.
