Transform Shift No Longer Maintains Aspect Ratio in Photoshop

I've been using Photoshop since it first came out.  It's as if someone cut off my right and left arms and switched them. It's okay if you want to have things scale proportionally WITHOUT holding the shift key down, but making the shift command do the exact OPPOSITE is disrespectful to us old-timers! ha.

I don't understand why they introduce a feature that works inconsistently. Sometimes I have to use shift, sometimes I don't.... it's incredibly confusing.

Same goes for Command + Z, why are there two different functions tied to the same shortcut?

Its a new update in Adobe photoshop Cc 2019 Without holding shift now you can maintain the aspect ratio.

1:- If you want to resize any image, or any Raster object then you no need to Hold Shift to main the Aspect ratio. Just re scale it from any corner.

2:- If you want to resize a Vector object or Shape then you need to Hold shift to maintain the Aspect Ratio.

PS: Its lit bit confusing for the old user of photoshop but they make it easier for the new users.

Hi, Yes In PS Cc 2019  Shift no longer maintain the aspect ratio.

Check this out.

Photoshop now transforms most layer types (such as pixel layers, type layers, bitmaps, Placed Smart Objects) proportionally by default. Shapes and paths, that is vectors, still transform non-proportionally by default.

When transforming a layer, you no longer need to hold down the Shift key while dragging a corner handle to resize a selected layer to constrain its proportions. Anytime you drag a corner handle during transform and move it, the layer resizes proportionally. Holding down the Shift key now resizes non-proportionally when you drag a corner handle during transform.

To resize a layer proportionally during transform, do the following:

1. Select the layer(s) you want to resize in the Layers panel.
2. Press Command + T (Mac) / Control + T (Win). Alternatively, choose Edit > Free Transform.
3. Drag a corner handle on the bounding box to resize the layer.
4. Commit the changes.

You can revert it.

How do I turn off the new proportional scaling by default behavior while transforming layers?

To revert to the legacy transform behavior, do the following:
Use Notepad (Windows) or a text editor on Mac OS to create a plain text file (.txt).
Type the text below in the text file:

TransformProportionalScale 0
