Curious whats the release date for this fix? thanks.

[jcoyne]

@kapso this is an issue report, not a fix.

[kapso]

@jcoyne true, thanks for correcting me :)

[9mm]

Also wondering

[aardvarkk]

Just ran into this myself.

[jcoyne]

Hey y'all, this is just an issue. The fix for the issue is in #255. However, that doesn't pass CI because Rails 4.2 doesn't like sprockets 4. That issue is fixed in #256. So, this problem is already solved, it just needs to be merged to master.

[Fryguy]

Fixed in #255 . If you find any other Ruby 2.7 issues, please open more issues. Thanks!

Should be released in 2.2.0 before the end of the weekend.

[kapso]

@pkuczynski Curious if the 2.2.0 is coming out anytime soon? Thanks.

[pkuczynski]

Working on this as we speak. Wanted to fit in #250, which is done and still working on #266 and #258. Hope to finish today :)
