SMF 2.1.6 released

[Sesquipedalian]

Dear Members,

Simple Machines has released a new patch to the 2.1.x line of SMF, bringing our latest release version to 2.1.6.

This patch contains fixes for a few bugs that were introduced in 2.1.5, some of which could be frustrating to those who were affected by them:

• Fixes "Undefined variable $sid" errors when a user with cookies disabled visited the forum while queryless URLs were enabled.
• Fixes a database query error that affected MariaDB while trying to search inside a topic.
• Fixes a BBCode parsing bug.

SMF 2.1.6 is a minor hotfix for 2.1.5, and since 2.1.5 was released only a few days ago, we're including the release notes for 2.1.5 as well for your convenience.

• PHP support:
  
  • Raises the minimum supported PHP version from 7.0 to 7.1.
  • Adds support for PHP 8.4.
• Security:
  
  • Fixes some security issues. For this reason, upgrading is strongly recommended.
• User profiles:
  
  • Fixes errors when profile fields using the "nohtml" mask are given values with Unicode characters or quotation marks.
  • Adds a new, separate permission for using Gravatars.
• Attachments:
  
  • Several fixes and improvements for the attachment upload UI.
  • Sets Content-Disposition header correctly for attachments for mobile browsers.
  • Improves handling of SVG image attachments
  • Adds support for WEBP images.
• Editor and BBCode:
  
  • The "Quote Selected Text" button is now more tolerant of "messy" selection ranges.
  • Shows "Last Edit" info (if applicable) when editing a post.
  • Improves smileys popup behavior.
  • Improves image quality of previews for embedded attachments in the WYSIWYG editor.
  • Fixes bugs in a few edge cases when parsing BBCode.
  • Centers BBCode tables wrapped in the center BBCode.
  • Fixes PHP syntax highlighting in BBCode under PHP 8.3+.
  • Fixes issues with broken HTML entities in warning templates.
• Calendar:
  
  • Shows multiple calendar events on the same day correctly.
• Search:
  
  • Fixes undefined variable error in custom search API.
  • Fixes a bug where the last character of a Unicode search term could be mangled.
  • Returns correct search results when post moderation is enabled.
• Email:
  
  • Notification emails always use display names, never usernames.
  • Improved handling of SMTP errors when sending emails.
  • Fixes a bug where undeliverable emails might never clear from the mail queue.
  • Accepts wildcards in email-based ban triggers.
• Admin:
  
  • Updates Unicode data files in a background task. (This ensures the forum will always have up-to-date support for the latest emojis and such.)
  • Fixes bug where rearranging boards in the admin center could cause some boards to temporarily not be shown.
• Other:
  
  • Fixes errors in RSS feeds for messages by members with commas in their usernames.
  • Fixes the integrate_error_types integration hook.
  • Fixes the integrate_attachments_browse integration hook.
  • Fixes open_basedir warnings in PHP 8.
  • Fixes some minor UI bugs.

Please see the change list for 2.1.5 and the change list for 2.1.6 on GitHub for more information.

How to update to 2.1.6

If you are currently using version 2.1.5, you can perform the update using the Package Manager (Administration Center > Package Manager). There you should see a notification about 2.1.6, including a "update your forum" link. If you do not see this notification in the Package Manager, please run "Fetch Simple Machines files" from the Scheduled Tasks page (Administration Center > Maintenance > Scheduled Tasks), and then try again.

If you are currently using any version from 2.1.0 to 2.1.4, you can use the process described above to apply previous update patches successively until you reach version 2.1.5.

If you are currently using any older version of SMF (including SMF 1.x, SMF 2.0.x, or one of the SMF 2.1 Betas or RCs), you can upgrade directly to 2.1.6 from whichever version you are currently using by using the "Large Upgrade" package from the Download page. Be aware that using this upgrade method will require you to reinstall any customizations that you have added to your forum, so if you are running SMF 2.1.0 or higher, it is recommended that you apply the successive patches instead of using the Large Upgrade.

If you are having problems downloading the patch from the admin panel, you can download the patch package from the Package Manager Updates page and install it via the Package Manager, as you would any other mod package.

Please refer to the Online Manual for more details about patching and upgrading.


Finally, as always, please do not use this topic for support requests. You will receive a much quicker and better response by posting in the 2.1.x Support Board.

Thank you for using SMF!

Regards,
Simple Machines

Thanks for the long awaited updated.
Today surprised to see update after 2 years from 2.1.3 to 2.1.5 inside the admin page and updated to 2.1.5 and found the error log pilling up and immediately found 2.1.6 which was not showing inside my admin page automatically, but downloaded from smf website and updated my forum to 2.1.6 from here https://custom.simplemachines.org/index.php?action=patches

Thanks for the update team. Done a nice job as usual. Smf developers are amazing always for last 20 years now almost.
