what different?
they have same description

The official difference, is that entries that are preceded by !+ NOT_OPTIMIZED in the regular version, are not included in the Optimized version.

I can also see that whitespaces, !+ PLATFORM criteria, and most source-context comments are removed in Optimized as well, resulting in a filesize of ~40% of that of the regular version.

Thanks, @DandelionSprout . Worth it to update the description(s)? Or, nah?

[DandelionSprout]

I'm not 100% certain at the top of my head. I'll need to think about it for some hours/days.

[DandelionSprout]

After a significant amount of Googling, I've found https://adguard.com/en/blog/adguard-browser-extension-2-1.html; which claims that the optimized filters [were/are] based on AdGuard telemetry that aimed to figure out which entries that were frequently applied, and to a smaller degree excluding entries with !+ NOT_OPTIMIZED above them.

This rules out a previous theory I had, in which they'd have tried to get under iOS and Safari ≥12's 50,000-entry limit.

Meshkov confirmed on the new Slack listmaker server that all four of the following factors behind the optimising were officially intended:

• Being light on memory.
• Only applying entries that AdGuard's opt-in telemetry shows to be frequently applied.
• Getting under iOS and Safari ≥12's 50,000-entry limit.
• Simply just removing comments and info links.

So I'll hereby add it to my(/our?) to-do list.
