v3.0.0 update (unreleased)

Major new feature: add generic bot detection

User Agent strings are scanned for the keywords "bot", "crawl", or "spider" - any User Agents not already detected as a bot which contain one of these strings are stored in the cache and made visible through the admin UI, with the option to have this information emailed on a weekly basis.

new bots: AccompanyBot; PostmanRuntime

v3.1.0 update (took less than 5 minutes after installing it on several of my production forums to identify new bots!!)

new bots: amazonbot; petalbot; slackbot

Lots of new bots, including UptimeRobot suggested by @Nirjonadda. See FAQ for complete list of bots now detected.

New functionality: tool to test bot detection - paste in a user agent string and the tool will tell you if it detects a bot
