The Lasso Tool is present within the new mask and select of 2015.5. The Polygon Tool is not provided however. Having both tools would be incredibly helpful.
I was completely baffled at first, but I've found where they've hidden it!
At the bottom of the toolbar, there's now a "..." menu beneath the zoom tool. This appears to have everything listed that Adobe have deemed less useful than the other toolbar tools (patch/healing brush/paint fill, polygon etc).
At the very top of this list there's the option to "Edit Toolbar". Click that, and edit the toolbar as you see fit. The option for a magnetic or polygon lasso is contained within. Enjoy!
Edit: This only seems to be a problem in the workspace I had selected, which was Graphics & Web. The default "Essentials" workspace has it in its expected location, nested in the polygon tool.
Thank you both for responses. Alt doesn't bring up the polygon tool for me. I also don't have an ellipsis on the tools toolbar while in mask and select. I've tried a few different work spaces and dont find that I have those options.
1. Click and hold down the mouse 2. While the mouse button is still down, hold down the alt key 3. With the alt key still down, release the mouse button
You should now be in the polygon tool.
I'll pass on your suggestion to the Select and Mask eng team.
