Docker transitioned from version 1.13 to 17.03 as part of a significant change in their versioning scheme. Prior to this change, Docker used a traditional versioning system, with versions like 1.12 and 1.13. However, starting in March 2017, Docker adopted a new versioning format based on the year and month of the release, known as the YY.MM versioning scheme. This change was implemented to provide a clearer and more predictable release cycle, making it easier for users to understand the recency of a release and plan for updates accordingly[1][15][16][19].
The first release under this new scheme was Docker 17.03, indicating it was released in March 2017. This new versioning system also introduced a monthly release cycle, with each monthly release receiving security and bug fixes until the next monthly release, and quarterly releases receiving support for four months after their initial release[1][15][16].
