yq adds base64url operators
Introduced 2026-09-29 · score 0.95
HOW TO USE IT
When a value needs URL-safe Base64 transformation, use `@base64url` to encode it or `@base64urld` to decode it. The release identifies these operators as RFC 4648 §5; the docs do not show examples for these specific operators.
