 Images tags format is `[VERSION]-[STABILITY_TAG]` where:
 
-**`[VERSION]`** is the **version of an application** (without patch version) running in a container, e.g. `wodby/nginx:1.15-x.x.x` where Nginx version is `1.15` and `x.x.x` is a stability tag. For some images we include both major and minor version like PHP `7.2`, for others we include only major like Redis `5`.

For some images we include both major and minor version like PHP `7.2`, for others we include only major like Redis `5`. 
 
-**`[STABILITY_TAG]`** is the **version of an image** that corresponds to a git tag of the image repository, e.g. `wodby/mariadb:10.2-3.3.8` has MariaDB `10.2` and stability tag [`3.3.8`](https://github.com/wodby/mariadb/releases/tag/3.3.8). New stability tags include patch updates for applications and image's fixes/improvements (new env vars, orchestration actions fixes, etc). Stability tag changes described in the corresponding a git tag description. Stability tags follow [semantic versioning](https://semver.org/).

 We highly encourage to use images only with stability tags.
