Project title: Deprecation cleanup and development process streamlining for Wiki Education Dashboard
Brief summary:

Wiki Education Dashboard is a complex Ruby on Rails application that supports editing programs and newcomer outreach for Wikipedia and other Wikimedia projects. It's been in production for more than 12 years, and has an active development community, and has recently been update to run on up-to-date versions of Ruby and the Ruby-on-Rails framework. However, many parts of of the system are still using outdated libraries, or haven't been updated to account for deprecations.

The focus on this project will be to systematically clean up sources of warnings, update deprecated code patterns, and generally clean up as many of the rough edges and developer-faciing problems as possible.

Expected outcomes: Fix many deprecation warnings and get the Dashboard codebase (and related services) running much more cleanly

NEW QUESTIONS
What WMF priority does this project align with? Via the broad impact of Wiki Education Dashboard codebase (and Programs & Events Dashboard in particular), this aligns broadly with the WMF priorities of "Responsible Use of Infrastructure", "Support Wikimedia projects" and "Strengthen the movement".
Why are you proposing it? This will help shore up the Dashboard's codebase and infrastructure, so that we can keep adding features and improving the system smoothly.
What is the expected impact? The expected outcome is a cleaner Dashboard codebase that fixes problems and technical debt before they become urgent problems and affect end users.
