Hello and thank you for your inquiry.  vWorkspace version 8.6.3 is the last release, but we will continue to monitor any defects and publish critical hotfixes as needed, as well as the connector updates.  It’s normal to leave the Product Life Cycle dates blank for the most recent release.  We will continue to support our customers through their maintenance terms. I hope this answers your questions above.
Dell announced last year that it will shut down development in vWorkspace.-:(  Big question for us: is vWorkspace 8.6.3. really the last version or may we expect newer versions (f.e. 8.6.4)? In the Product Life Cycle table the dates for full support for 8.6.3. are left blank. Normally, this dates are filled in when a new version arises. Since it is unclear whether or not a new version will be developed, I would appreciate it if Dell would indicate till which date version 8.6.3. will be supported anyway (f.e. "8.6.3. will be fully supported till 1/1/2019 or later") ?  
Will vWorkspace 8.6.3 be the last version?
