  In July 2020 the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 2.1 specifications were revised to add support for the [[Validation and Transformation Language>>doc:sdmx:Glossary 2\.1.Validation and transformation language.WebHome]] ([[VTL>>doc:sdmx:Glossary 2\.1.Validation and transformation language.WebHome]]). For 3.0, the [[VTL>>doc:sdmx:Glossary 2\.1.Validation and transformation language.WebHome]] specification has been updated to align with changes to the information model and other modifications to the Standard such as the introduction of Semantic Versioning for the versioning of [[structural metadata>>doc:sdmx:Glossary 2\.1.Structural metadata.WebHome]] [[artefacts>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]]. Section 2 (Information Model) sets out details of the ‘Transformation and Expressions’ package for defining and managing [[VTL>>doc:sdmx:Glossary 2\.1.Validation and transformation language.WebHome]] 2.0 programs and Section 6 (Technical Notes) provides detailed guidance on implementing and using [[VTL>>doc:sdmx:Glossary 2\.1.Validation and transformation language.WebHome]] with [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]].
  = 2 Change History =
--The 2.0 version of this standard represented a significant increase in scope, and also provided more complete support in those areas covered in the version 1.0 specification. Version 2.0 of this standard is backward-compatible with version 1.0, so that existing implementations can be easily migrated to conformance with version 2.0.
++The 2.0 (% style="color:#e74c3c" %)version(%%) of this standard represented a significant increase in scope, and also provided more complete support in those areas covered in the (% style="color:#e74c3c" %)version(%%) 1.0 specification. (% style="color:#e74c3c" %)Version(%%) 2.0 of this standard is backward-compatible with (% style="color:#e74c3c" %)version(%%) 1.0, so that existing implementations can be easily migrated to conformance with (% style="color:#e74c3c" %)version(%%) 2.0.
  The 2.1 (% style="color:#e74c3c" %)version(%%) of this standard represents a set of changes resulting from several years of implementation experience with the 2.0 standard. The changes do not represent a major increase in scope or functionality, but do correct some bugs, and add functionalities in some cases. Major changes in [[SDMX-ML>>doc:sdmx:Glossary 2\.1.SDMX-ML.WebHome]] include a much stronger alignment of the XML Schemas with the Information Model, to emphasize inheritance and object-oriented features, and increased precision and flexibility in the attachment of metadata reports to specific objects in the [[SDMX Information Model>>doc:sdmx:Glossary 2\.1.SDMX Information Model.WebHome]].
