IN BRIEF:

I’m seeing a lot of library and tool releases explicitly dropping Node 12 support in their latest versions, so if you’re still using Node 12 anywhere, upgrade ASAP (or, at least, take a lot of care when updating dependencies).

RELEASES:

pnpm 7.0 – Efficiency-focused npm alternative.
Mocha 10.0 – JS test framework.
ShareDB 3.0 – OT-based realtime JSON database.
Cucumber.js 8.2 – BDD / plain language testing.
npm 8.9.0
