Render Renamed Every Compute Plan to 2c-4g Style IDs: An IaC Compatibility Checklist Before You Touch Anything
Render's August 26 rename turned Pro Plus into 4c-8g and promised no action required. The grep commands that inventory every plan reference, the three spellings of each plan, the Workflows flex gotcha, and a six-step checklist that proves an IaC fleet is clean.
Railway Patches Your Postgres When a CVE Lands — What Vendor-Side Patching Costs vs. Patching It Yourself
Railway now patches your Postgres when a CVE lands — but the restart still happens on their schedule, not yours. A side-by-side runbook comparison with patching Postgres you own via CloudNativePG, worked through the 28-CVE August 2026 release, with a verdict for three tenant profiles.
