   Sorry for the trouble.
   
   > What is the Volcano versioning?
   
   - Volcano release docker image with specific tag, such as v1.5.0, next 
release would be v1.5.1
   - Fixes will merge to latest and then backport to v1.5.x.
   
   > I don't believe this is sustainable to depend on latest
   - We use master latest images for spark IT test before. **I have to say 
sorry about this, I also think it's my fault to make this decision**, I just 
considered it's also very import for us to do continuesly validation but 
ignored the stable factor. 
   - We need to use release-1.5/installer/volcano-development-*.yaml to do 
validation for spark 3.3, I also track issue on: 
https://github.com/volcano-sh/volcano/issues/2076 to release v1.5.1 beta 
release for continuesly validation, this issue will be completed today.
   - These also expose some shortcomings of Volcano in dev versioning in cross 
community, but the Volcano community is also actively improving, hope you can 
understand.
   
   > which Volcano version has these enforcements?
   
   Always, but as I mentioned before, there was a compatiable problem in v1.5.0 
webhook feature (admissionconrol, input parameter validation) are not work in 
v1.5.0 with K8S 1.22+, so we didn't see this enforcements. Epecially in 
kubernetes v1.22+ because of 
[admissionregistration.k8s.io/v1beta1](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#webhook-resources-v122)
 drop, alread be fixed in volcano master 
https://github.com/volcano-sh/volcano/issues/2063 and will be backported to 
v1.5.x soon.
   
   > which Volcano version can delete the Open queue?
   
   - Volcano can delete the Open queue improvation for ease of use since 
v1.5.1.beta.0 until queue close API supported.
   - Volcano will also supported close queue api in follow release.
   - No more impact on Spark in some level. For Spark 3.3, we can delete queue, 
For Spark followup release, I need add a queue close operation before delete 
queue in IT, and also bump volcano new version in followup Spark release.
   
   TLDR:
   - https://github.com/volcano-sh/volcano/issues/2076 volcano is going to 
release a v1.5.1-beta.0 for continuesly validation, we still can use 
release-1.5/installer/volcano-development-*.yaml to do validation as 
https://github.com/apache/spark/pull/35822 doc. @dongjoon-hyun Thanks for doc 
this!
   - Then I will do a validation on with volcano `v1.5.1-beta.0` make sure all 
volcano feature works before 15.March.
   - This PR will be mark as ready for review soon. : )
