Snow Owl v9.2.0

API

• New ETag, If-None-Match and Cache-Control HTTP header support (#1270)
  • Content HTTP responses now have an ETag header value generated based the queried branch reference
  • Cache-Control header value is also being returned using the api.cache_control configuration setting
    • Default value is s-maxage=0,max-age=0,must-revalidate which ensures that caching can happen but the cached response has to be revalidated before using
  • If-None-Match header is now also supported to allow clients to send the ETag value and receive a HTTP 304 Not Modified when revalidating an earlier response. This allows the cached response to be used until it is not overridden by the server with a new response.

Bugs/Improvements

• [ecl] wild lexical searches now use the wildcard index query for better user experience (030304a)
• [api] properly response with an HTTP 400 Bad Request response when a required query parameter is missing (#1273)
