What am I missing here? Still says i'm at 92.6% used. Wow, I can't believe the order of magnitude size increase we're getting. from 0.06megabytes to FOUR GIGABYTES

Doesn't it only kick in when you overrun the (old) limit?

The display in the string editor only kicks in when its over the limit (Since it currently doesn't know what format the map is/will be saved in), the new format kicks in as soon as you save in SCR compatible map format.

Did Blizz announce this change anywhere or was it like a hidden update?

It's no longer giving me percentage but it is still saying my cap is 1877 strings. I'm gonna assume this is like a visual error.

HELL YES 4GB STRINGS GET HYYYYYYYYYYYPE!

It was in the 1.23.1 patchnotes

That cap is the maximum number of strings in the current string table - it is expanded on the fly though nowadays so its not that meaningful. Maybe that should be changed / removed to just saying how many strings are in use.
