Migrating to 2.1

2.1 keeps the API of 2.0: every prop and export still exists. Some defaults changed to make codes scan more reliably, and the drawing got cleaner.

Visible changes

2.0	2.1
dots and triangle drew the eyes as dots / diamonds	Solid eyes and alignment patterns (circle for dots, square for triangle and separated). finderPattern={false} restores the old look.
A logo used error correction level M	Level H unless you pass errorCorrectionLevel
Every module was a separate shape, which could show hairline seams	rounded and square are traced as whole outlines: same shapes, no seams, half the path data
The requested error correction level was used as is	It is raised when that fits into the same size

Smaller changes

• The modules are one <Path> (testID qr-code-module) instead of two; styled eyes are drawn by extra paths with testID qr-code-finder.
• gap must be at least 0 and less than 0.5; other values throw.
• qrcode and nanoid are no longer dependencies; encoding uses uqr.

New

• shape="liquid", finderPattern, quietZone.
• qrCodeToSvgString and encodeQr, for use without React.
• Development warnings for logos and styles that may not scan.
