BookStack Release v22.02

Today we announce the first BookStack feature release of 2022. This brings updates & features to the WYSIWYG editor, user management API endpoints and much more. In this post we cover features added in this release in addition to some notable changes in the v21.12 patch releases.

Upgrade Notices

  • PHP Requirements Change - The minimum required version of PHP has changed from 7.3 to 7.4.
  • Composer Requirements Change - As of release v21.12.3 composer version 2.0 or greater is required. See our v21.12.3 update notes for details on upgrading this.
  • Security Releases - During this last release cycle there was a security update. See the v21.12.1 blog post for more detail.

WYSIWYG Editor Updates

The main work for this release has been focused on the WYSIWYG editor. The library used by BookStack, TinyMCE, has been updated to a much newer version and we’ve reorganized the connected BookStack codebase.

In terms of usage, everything should remain familiar. The most apparent changes are to the toolbar:

New Editor Toolbar Styling

The styling and size of the buttons has changed to be a little more modern and easier to use. The location of some buttons have been moved, with lesser-used controls being placed behind overflow menus to keep the default toolbar focused & simple. Code formatting options have been moved out from the block formats dropdown to instead be inline & insert options. A new help “(?)” toolbar button has been added to show editor license information in addition providing a handy list of available shortcuts.

For those using BookStack in a language other than English, the editor is now linked to our translation system meaning that, where language files have been updated, controls within the editor should now be in your preferred language:

Example of editor controls in French

You’ll probably notice other usability and speed improvements gained by the more modern underlying library, otherwise all existing features and abilities should remain the same.

Within this release cycle I did spend some time exploring alternative options but I found that moving away from TinyMCE would be quite a painful process for us so instead I chose a more stable path for now.

Collapsible Content Block WYSIWYG Editor Support

For the first time in while we’ve added a new content type to the WYSIWYG editor: The collapsible content block. These blocks allow the grouping of multiple other blocks of content into a container that can be toggled open by the reader.

These blocks are open within the editor and closed when viewed on a page. They can be toggled closed within the editor for cleaner editing or previewing purposes. The label used on the toggle bar can be edited as desired. When page content is exported these sections are still represented although in an open state so that content is visible.

Behind the scenes these blocks use the HTML standard <details>/<summary> elements as described on MDN here. Markdown users have been able to use these within BookStack, using the HTML representation, but the inclusion in the WYSIWYG editor helps align abilities.

The addition of these blocks adds some great potential use-cases to empower your documentation; From cleaning up large detailed sections or code-blocks, to being able to provide spoiler-free question and answer style content:

User Management API Endpoints

In this release the API receives another set of abilities. There are new endpoints for user listing, creation, updating and deletion. All of these actions require “Manage Users” role permissions by the API client user.

Preview of user API docs

These new endpoints unlock a whole new avenue for automated and programmatic user management in addition to allowing bulk operations to be script-able. Need to migrate thousands of users into BookStack? Now it’s possible!

You can find more detail for these endpoints via our demo site API docs.

Webhook Improvements

BookStack v21.12 added support for outgoing webhooks. In v.21.12.1 this system was enhanced with the following additions/changes:

  • Webhook network errors will now be caught as to not break next page loading.
  • Webhook “Last Called” time, “Last Errored” time and “Last Error” messages are now recorded against the webhook and shown in the webhook edit page for easier debugging.
  • The HTTP webhook call timeout is now configurable per-webhook.

Example of webhook debug details

These changes should greatly improve the debugging process, if needed, when setting up webhooks while allowing them to be used in a much more reliable manner.

Language Selection on User Creation

As of v21.12.4 you can now select a preferred language when creating a new user in the system:

New user language select control

Upon showing the correct language upon first login, this means that the new user can now receive the invitation email in the most suitable language, instead of it being based on the language of the admin creating the user, which was not very intuitive.

PDF Export Page Size Option

A new .env option was added in v21.12.4 to provide control over PDF export page size. By default Bookstack will use an A4 page size but this can be changed to “US Letter” size by adding the following to your .env file:

# US Letter PDF export size

Enhancements to the “Recently Updated Pages” List

In BookStack v21.12.3 the “Recently Updated Pages” view, accessed via the homepage card of the same name, was enhanced with some additional context-specific details:

  • Last update author and last update time are now shown.
  • The parent book/chapter chain are displayed for each item.

Special thanks to @Julesdevops for helping to evolve this area of the application.

Development Git Branch Changes

For those closer to the BookStack code, within the last release we’ve changed the default development branch name from master to development. This was to add clarity to the branch’s purpose while avoiding any potential concerns of offence.

If you have any existing links or branch references, GitHub should redirect and/or warn about this change upon interaction.

Next Steps

This release was the first in working upon our “Editor Alignment & Review” road-map item. For this next feature release I’ll be looking to get deeper into this road-map item to align markdown & wysiwyg feature-sets and potentially offer easier traversal between these editor options.

With the updates made to the WYSIWYG editor I think it’s likely we’ll have a flurry of patch releases to enhance features and patch issues that pop up from wider usage.
