Changes in YQL versions

This section contains a list of changes in different versions of the YQL

General description of YQL versions

The goal of language versioning is a controlled and user-safe evolution of the language, within which it is possible to:

• add new features;

• change default values ​​for pragmas or perform other non-backward-compatible changes;

• remove obsolete features.

The starting version of the language is 2025.01.

Once a year, a new version of the language is released, called YEAR.X, for example 2025.01. Other versions in the same year will increase the minor version number (YEAR.02, etc.).

For each version of the type YEAR.X support is guaranteed for three years with the preservation of semantics and bug fixes.

When version YEAR+2.1 is released, a warning is issued for all versions of the type YEAR.X that they will soon cease to be supported.

When version YEAR+3.1 is released, a warning is issued for all versions of the type YEAR.X that they are not supported and query execution is not guaranteed.

When specifying a version of YEAR.X greater than what is currently available in some service/library/tool, a query error is issued.

When each version is released, the documentation in the changelog indicates the changes included in this version and recommendations for migration.
