HCL does not yet announced date for 9.2.16 release of the BigFix Inventory.
HCL Team is working towards providing Software Catalog update in first place and then complete product release.
Indeed IBM by mistake has published information about BigFix Inventory 9.2.16 via Security Bulletin as well as IBM Knowledge Center.
Please discard any information from IBM about versions of BigFix Inventory newer than 220.127.116.11. It was the last release provided by IBM. All further BigFix Inventory releases will be announced by HCL via HCL channels.
