4.2.7

• Removed: The declaration of the type has been removed from class-helpful-setup.php because it was not compatible with low PHP versions.

4.2.6

• Fixed: Fixed a bug where the placement of shortcodes was not possible.

4.2.5

• Fixed: Fixed a bug where the parameters for the shortcode were wrong.

4.2.4

• Security: Security has been improved by not being able to access the files directly anymore.
• Fixed: Fixed errors when loading Helpful by using the hook plugins_loaded instead of init.
• Fixed: Fixed a bug where the customizer could not be loaded because Helpful had loaded its own customizer options incorrectly.

4.2.1

• Fixed: Corrected translations.

4.2.0

• Before updating: A lot of things have been rewritten in the background. If you encounter problems, you can download version 4.1.4 here.
• Added: In the Helpful settings there are now datatables in which all previous votes can be found. If the tables are too slow, caching can be set. The caching can be configured under Helpful -> System.
• Changed: Chart.js and datatables are now loaded with CDN.
• Fixed: The Helpful metabox now shows the correct values again.
• Fixed: In the overviews in the admin area you can now sort the Helpful columns by clicking on a column header.
• Fixed: Fixed a bug that caused visitors or people who voted to be saved without ID.
• Fixed: CSS corrections.

4.1.3

• Added: Helpful now also detects loops and can thus be used more than once on a page when Helpful is placed in a loop. This is useful, for example, if you want to integrate Helpful into a FAQ.
• Added: You can now store a Post ID in the Helpful shortcode if Helpful does not recognize the post - or if you want to use Helpful outside a loop ([helpful post_id="12345"]).
• Fixed: Minor bug fixes in the translations and the wpml xml.

4.1.2

• Added: If a user is logged in and gives feedback, the data from his or her profile is used.
• Added: Helpful now has its own Elementor block.
• Fixed: Minor bug fixes in the Admin Widget.

4.1.1

• Fixed: Fixed an error message in the Helpful settings. The SVN commit swallowed a file. It should be back now. The plugins should finally be hosted on Github, my goodness!

4.1.0

• Added: There are new options for feedback under feedback in the helpful options. You can now send your feedback by email. You can also add individual receivers directly to Helpful's Metabox.
• Added: If WP_DEBUG and WP_DEBUG_LOG are set to true, errors are stored in the debug.log of WordPress. This should help to detect errors in the future (Debugging in WordPress).
• Changed: The number of entries displayed in the widget is set to 3 by default. There was no default number in the widget before.
• Changed: Required PHP version updated from 5.2 to 5.6.20 (Minimum PHP Version update).
• Changed: WordPress 5.3 tested.

Helpful on Github is now working with the releases to make it easier to work together. Unfortunately I didn't do that before. The documentation on the official website has been extended (Helpful Documentation).
