As you all aware of that new version of business central 2024 Wave 1 is knocking the door but before that we already got new AL language extension with many changes. The points which I can feel most useful as below

1. Support for multiple extensions to same target and extensions and target in same app
   • This means if you are working in one of the app and based on some requirement if you want add field in one of the base table then you can create table extension for that table in the same app. Personally, I still not figure it out how I can use it in my application. (Lets give a try).
2. Support ended for debugging Business Central server versions less than 20
   • Once you install this new version of AL language then Business Central server versions released before the April 2022 release (version 20) cannot be debugged with AL extension package versions that are greater than or equal to version 13.
3. Tooltips on table fields
   • Introduced the tooltip property on table fields, which like the caption will be applied on page controls that reference the table field. This includes a code action that helps with moving the tooltip from page controls to table fields or cleans them up from the page in case of duplicates.
   • To get this property enabled please set runtime version as 13.0 in app.json

Note : If you already set tooltip property on table and then you try to move the page tooltip then you can see code actions is not available.

4. Placeholder text on Page Fields

Page fields can now leverage the InstructionalText and InstructionalTextML properties to define placeholders. These values will be showed when the field would otherwise be empty.

Using this new capability, you can provide example values to your users. This feature is currently supported only for text types like Text, BigText, Code, and Guid.

5. New “Create AL Project” button

• This is replacement of AL:GO!
