Custom stats were improved: now you can use your own variables and set them on-the-fly.
Weapons now show energy consumption.
The Overcharge Cannon now also has a tooltip explaining its mechanics

Now, for EMP weapons - you can see the description of the stun effect. 

It even works for the death EMP of a Loyalist or Aeon's Chrono Dampener.

Enjoy!

Notes:

The stun radius works slightly differently than the regular damage radius (it just ignores hitboxes), but it feels too complicated to explain in the database itself.

Also, the Loyalist's stun does not stun air units, but it works differently than the category filter - it's hardcoded differently in the Lua code and not shown in the database, since it doesn't seem worth hardcoding extra conditions.

There was a big issue with torpedoes and depth charges. While both are in the 'Anti Navy' weapon category, they are different—depth charges ignore anti-torpedo defenses. On top of that, some depth charges cannot target water-surface-level units at all. Many people didn't know this because they had no way of finding out unless they looked at the code or tested the game extensively

From now on, this issue is fixed—everything is clear, and the Exodus now has its targeting limitation shown in a tooltip

The unit database (in view A) is now optimized and can be run even on potato PCs with integrated graphics. Previous issues (especially in Firefox) have been eliminated with almost no loss in visuals.

https://faforever.github.io/etfreeman-db/ is now a PWA (Progressive Web App), so you can install it on your mobile phone.
Just go to the site, and the prompt to install it as an app should appear eventually.

Enjoy!
