Dev Build 3100 is out now at https://www.sublimetext.com/3dev

It’s mostly a collection of fixes, and now uses a new code signing certificate on Windows, now that Microsoft have deprecated SHA1. If you are using Windows, you may want to download the full installer, rather than use the update. My understanding is that this will then help build reputation for the new certificate, so that SmartScreen will eventually stop complaining about it.

Also in 3100 is the new “Plugin Development: Profile Events” entry in the Command Palette. You can use this to see if any plugins are doing too much work in the main thread in response to events. Note that it doesn’t currently report on any time spent in set_timeout, but likely will in the future. Time spent doing work in a Command isn’t monitored, as that happens in direct response to a user choosing to run the command.
