Release notes for 673

Ensures that subtyping errors are reported correctly.

Speeds up animation curve evaluation by enabling caching for animation curve sampling.

In "Next Gen Explorer" beta, fixes several issues of actions showing when they shouldn't, or not showing when they should.

The keyboard shortcuts for cut and copy can now be triggered in the Script Editor with no text selected. If a cursor has no selected text, the cut and copy actions will place the entire line the cursor is on into the clipboard.

Pasting a clipboard item sourced from a single line cut or copy will place it on the previous editor line.

Pressing Enter or F2 to rename an instance can now be done after selecting from the viewport, without having to click on the Explorer window.

In Luau's New Type Solver, fixes a bug where the index, rawget, and setmetatable type functions mistakenly had a default value for their second type parameter.

Some mice such as "Microsoft Ergonomic Mouse" send scroll deltas other than -1 or 1 which tricks the input stack into thinking their scroll is a trackpad scroll disabling smooth scrolling in the Windows client.

Use a better heuristic to avoid this.
