In addition to functional and object oriented language features, Dyalog APL folded concepts and features from the [[SHARP APL]] and [[J]] side of the APL family tree back into what fundamentally remains a dialect of APL2. In 2011 the company hired [[Roger Hui]], developer of J, and in 2016 it also hired J programmer and language implementer [[Marshall Lochbaum]]. Both developers improved performance of Dyalog's primitives on flat arrays, and brought concepts such as the [[Rank (operator)|Rank operator]], [[trains]], and [[Function composition|composition operators]], namely [[Atop]] and [[Over]], from J to APL. | In addition to functional and object oriented language features, Dyalog APL folded concepts and features from the [[SHARP APL]] and [[J]] side of the APL family tree back into what fundamentally remains a dialect of APL2.

In the 2010s, Dyalog development began to focus on performance, which had been improved out of necessity in early releases but had not been a major focus. In 2010 Dyalog Ltd. hired [[Jay Foad]], a compiler developer who initially created a bytecode compiler for APL and later improved performance in other ways, and served as CTO from 2016 until his departure in 2019.

The Dyalog interpreter has also incorporated significant components written in APL in the 2000s and 2010s. [[Dan Baronet]], hired in 2006, introduced the SALT (Simple APL Library Toolkit) system to distribute APL code, and [[user command]]s based on it, in [[Dyalog APL 12.0|version 12.0]] in 2008. Work on APL components of Dyalog has also been done by [[Brian Becker]] and [[Adám Brudzewsky]]. Brudzewsky, hired in 2015, has also driven the adoption of new functionality such as [[Nest]] and [[array notation]] in Dyalog. | The Dyalog interpreter has also incorporated significant components written in APL in the 2000s and 2010s.
