Tracking all Dev Notes from Gutenberg plugin releases 14.2 - 15.1

Please read the information below carefully. If you have questions, connect with @bph or @zzap via Slack or comment here.

• 🗓 Deadline March 3rd, 2022

Not all developer related information needs to be in a separate DevNote on the Make Core blog for the field guide. We can group related information. We can already make decision on some features if it warrants a stand-alone blog post or if the information will be part of a group post.

Stand-alone post

To streamline the process and eliminate bottlenecks, all writers of stand-alone dev notes will receive privileges on the Make Core Blog. (Please connect with @bph or @zzap, if you need access)
Instructions

- Create your note in a new post, - Save as Draft - Enable public preview - Share the link to the public preview in a comment below, as "ready for review" - "For dev notes, each one must have at least two reviewers" ([Handbook](https://make.wordpress.org/core/handbook/tutorials/writing-developer-notes/))

## Part of a group post If the information related to your PR will be part of a group post, please write the **dev note in a comment on the PR**, so it can be reviewed and, if necessary commented on, by the release docs team or a reviewer.

Before you start writing 📣 please read the handbook pages:

- ⭐️ [Writing developer notes](https://make.wordpress.org/core/handbook/tutorials/writing-developer-notes/) - ⭐️ [Style & Substance section](https://make.wordpress.org/core/handbook/best-practices/post-comment-guidelines/#style-and-substance) of the Post & Comment Guidelines for Make Blog - ⭐️ [Documentation Style Guide](https://make.wordpress.org/docs/style-guide/) - Good for reference, when in doubt, especially when English is not your native language.

The list is incomplete. We are in the process of reviewing plugin release changelogs and add as we progress on the task.

There are two labels:
needs dev note and has dev note

If you worked on a feature/module/component that definitely needs dev note, please assign the label needs dev note If you already added the Dev Note to the make blog on draft or as comment on the PR, please label it has dev note
