This blog summarises changes made to slicers in the July, August, September and October 2026 Power BI updates.
This is what a numerical slicer (for example) looks like by default:

The unselected bit on the left and right is called the "tracker"; the bit which is selected is (not unreasonably) called the "selected range".
You can now format every part of the slider:

The old adage: just because you can do something, it doesn't mean that you should.
Here's what the above settings would show for our slicer:

Yuk!
There are more options for relative dates if you're slicing by a date column:

These extra settings apply if you've chosen to show a Relative Date slicer for a date column.
You can now choose calendar weeks, months or years from the dropdown which appears:

The full range of relative date options.
If you have chosen to display a slicer as a dropdown, you can now format this within inches of its life:

But again, just because you can do something ... !
Here's what the above settings would show:

The top left and bottom right rounded corners were probably a mistake!
There is now another visual slicer icon on the palette, albeit marked as preview:

The new list slicer is enabled in preview by default.
This new list slicer seems to me to replicate something which pretty much already existed:

The new list slicer is similar to a dropdown version of the existing standard slicer.
The big innovation is that you can choose to display a button asking that the items you've selected should appear at the top of the list:

Toggling this on means a user gets the opportunity to show the items he or she has selected at the top of the dropdown.
Right now I can't see the point of this new slicer, particularly as you can also apply the new Show selected first option to a button slicer, so I can only think Microsoft are intending to remove all dropdown options from the standard slicer at some stage in the future to simplify it.
