Workspaces::Tasks New Feature Our ::Tasks issue tracking application in Workspaces was upgraded last week to include an Activity Log for all tasks. In many cases log information has been retroactively added so if you click on a item in a Tasks list you'll see, at the bottom, a list of who's done what so you can ask the Hard Questions (or at least not look silly in meetings). Workspaces is free and you can have multiple Git repositories and Tasks lists in a single workspace. There's no limit to the number of workspaces you can create. We love it and use it and hope you do too.
