The original version of XSLT (1.0) was published in November 1999, and was widely implemented. Some of the early implementations have fallen into disuse, but notable implementations
actively used in 2023 include those integrated into the mainstream [[web browser]]s, as well as [[Altova]]'s RaptorXML, [[libxslt]], [[Saxon XSLT|Saxon]], the [[Microsoft]] [[.NET]] implementation '''System.Xml.Xsl''', and [[Xalan]] which is integrated into the Oracle [[JVM]]. These products all have a high level of conformance to the specification, though they also offer proprietary vendor extensions, and some of them omit support for optional features such as disable-output-escaping.

Subsequent versions of XSLT include XSLT 2.0 (January 2007) and XSLT 3.0 (June 2017); there is work in progress on a version 4.0. These versions have not been as widely implemented as 1.0: the main implementations in widespread use in 2023 are [[Saxon XSLT|Saxon]] (available in various versions for different platforms, including web browsers), and [[Altova]]'s RaptorXML.
