Not sure if Trac 1.0.10 has upgraded themes, I hope so, as when using "marks, e.g. marks=65-84#L63 to view source code on Trac with the Monokai syntax highlight theme it is practically unreadable:

e.g. /api.wordpress.org/public_html/dotorg/slack/subgroup.php?marks=65-84#L63:

Has anyone actually asked Systems to upgrade Trac?

[netweb]

The last update/upgrade request I can see on /systems is for 1.0.0 to 1.0.1 ​here

A seach of ​https://make.wordpress.org/systems/?resolved=unresolved didn't unearth a request nor did ​https://make.wordpress.org/systems/tag/trac/?resolved=unresolved

Could you make said request on systems please @pento

[pento]

I know it's not on make/systems, I was checking that @ocean90 or someone else hadn't pinged Systems on a different channel.

This isn't going to happen any time soon, unfortunately. I'm closing the ticket, as it's more likely that we'll move away from Trac before we find time to upgrade it.
