Commercial¶
Commercial versions of kdb+ are available to customers from downloads.kx.com. (Credentials for this site are issued to customers’ Designated Contacts).
Internal distribution
Most customers download the latest release of kdb+ (along with the accompanying README.txt, the detailed change list) and make a limited number of approved kdb+ versions available from a central file server.
Designated Contacts should encourage developers to keep production systems up to date with these versions of kdb+. This can greatly simplify development, deployment and debugging.
Platforms and versions¶
The names of the ZIPs denote the platform (l64.zip – 64-bit Linux; w32.zip – 32-bit Windows, etc.).
Numerical release versions of the form 2.8, or 3.5 are production code. Versions of kdb+ with a trailing t in the name such as 3.7t are test versions and are neither intended nor supported for production use.
