About Swagger UI
Swagger UI's release stream is dependency bumps and nothing else.
The last three tags contain no product changes at all: swagger-client bumped twice, plus axios, dompurify, and immutable. Each release is a patch tag with one or two dependency lines. The project is mature and widely embedded, and the visible activity reflects supply-chain upkeep rather than development on the interface itself.
