Possibility using latest programming language version
### 1. Summary
It would be nice, if would be possible, that Circle CI can automatically set the latest programming language version, that developers doesn't need to set specific version.
### 2. Argumentation
I develop Python packages. I want, that my packages works on latest Python version. Part of my example `circle.yml` file:
When new Python version release, I need to change `3.6.3` to `3.6.4` in each my project, then I should change value to `3.6.5`, `3.7.0` and so on. It may take a lot of time.
### 3. Expected behavior
Example part of `circle.yml`:
Circle CI will be automatically use the latest stable Python version, what is available on Circle CI.
### 4. Not helped
1. I read, for example, [this discussion](https://discuss.circleci.com/t/how-to-use-latest-python-version-instead-of-specific-version/11051?u=kristinita), but I don't find, how I can solve my problem.
