Slack has made it known that they're bumping up their minimum browser requirements as of March 15. They're going to require Chrome 66 or later.
Rambox: v0.6.3
OS: macOS 10.12.6
Arch: x64
Thanks for opening your first issue here! Be sure to follow the issue template!
The About Rambox dialog shows a Chromium version of 66 or newer.
The About Rambox dialog shows a Chromium version of 61.0.3163.100.
Rambox: v0.6.3
OS: macOS 10.14.3 (18D42)
Arch: x64
Currently getting this notification now and then when using Slack:

The link goes to the help article listed above.
We will release a new version of Rambox CE ASAP, and of course will be before March 15.
FWIW, I'm using Rambox Pro and have Amazon Music as one of my tabs - also getting a similar message (totally unrelated to Slack) about outdated Chromium version and deprecated support. Just another hint that it would probably be good to bump it.
@daveaglick also a Rambox Pro update will be coming soon (with an updated Chromium)
@saenzramiro what's the progress with 0.6.4? Just curious, I know it's not March 15th yet
Anyone willing to review PR #2111?
I鈥檝e tried on my machine; it refuses to launch the app even from upstream master:
Sencha Cmd 6.6.0.13 - Crash report

Did you install ruby ?
@maxerbox Yes, I do have Ruby聽2.6.1 installed. A 2.3.7 installation also came with the OS, which is macOS 10.14.3.
I鈥檝e upgraded sencha from 6.6.0.13 to 6.7.0.37 and run sencha app upgrade.
I still get the same error when running sencha app watch. 馃槥
Any ideas how to troubleshoot that?
Anyone else willing to review #2111? There鈥檚 only one day left in Slack鈥檚 grace period.
@claui
