Category	Suggestion	Score
Enhancement	Update multiple dependencies to their latest compatible versions for improved security and performance Consider updating other dependencies to their latest compatible versions to ensure optimal security and performance. packages/polyserve/package.json [50-53] "express": "^4.21.1", +"cors": "^2.8.5", +"http-proxy-middleware": "^2.0.6", +"lru-cache": "^7.14.1", Apply this suggestion Suggestion importance[1-10]: 5 Why: The suggestion to update other dependencies to their latest compatible versions is generally beneficial for security and performance. However, it lacks specific context or evidence that these updates are necessary or compatible with the existing codebase, which limits its immediate applicability.	5
