This page aims to cover in brief the history of the K dialects and their official implementations.
The original K specification
[1]Arthur Whitney left I.P. Sharp and Associates in 1992 to create a new language. Arthur Whitney formed Kx Systems jointly with Janet Lustgarten in 1993.
K2 and K3
K2 and K3 were the first commercially developed and supported versions of K made at Kx Systems. K3 came with a complete reference manual[2] that consisted of the documentation for the entire language. kdb+ was a database system that was sold along with K that provided an in-memory database manageable using K. In 2003, Q was released as a "wrapper around k providing readability".
K4
K4 is the current commercial dialect supported by Kx Systems, which is bundled alongside Q as an implementation language. K4 requires a command to switch from Q to K, and the documentation at code.kx.com does not cover K4.
Shakti(K7,K9): 2018-present
Arthur Whitney sold his majority stake in KX systems and departed along with a few of his associates to create a new company called Shakti, along with which came the creation and development of the K7 and K9 dialects.
K7 was maintained for a few years and is no longer available for use.
K9 is currently nascent and (as per the onsite claims)[3] supports fast processing of tables with row numbers in the billions and trillions. Binaries for K9
