Snap Store has release channels. For example - VLC player:
So you can choose channel and install the respective version:
| Channel | Version | Install command |
|------------------|-------------------------|-----------------------------------|
| latest/stable | 3.0.6 | sudo snap install vlc |
| latest/candidate | 3.0.6 | sudo snap install vlc --candidate |
| latest/beta | 3.0.6-50-g71bfa08 | sudo snap install vlc --beta |
| latest/edge | 4.0.0-dev-6398-g44b30c2 | sudo snap install vlc --edge |
For other Snaps this is completely dependent on Snap developer (which channels were created).
