[Updated 23/06 to reflect newer versions 2.1.2 and 2.2.1]
Heads-up: Autoptimize 2.2 has just been released with a slew of new features (see changelog) and an important security-fix. Do upgrade as soon as possible.
If you prefer not to upgrade to 2.2 (because you prefer the stability of 2.1.0), you can instead download 2.1.2, which is identical to 2.1.0 except that the security fix has been backported.
I’ll follow up on the new features and on the security issue in more detail later today/ tomorrow.
