Puedes ver las versiones disponibles (por ejemplo, para revisar cuál es la más reciente) en las [Release Notes](../release-notes.md).

## Sobre las versiones { #about-versions }

Siguiendo las convenciones del Semantic Versioning, cualquier versión por debajo de `1.0.0` podría potencialmente añadir cambios incompatibles.
