| + | # Data Channel Offload: supported features |
| + | |
| + | This page aims at summarizing all data channel features and their support status in the DCO modules across the supported platforms.\\ |
| + | New features may be added over time, therefore keep an eye on this page if interested. |
| + | |
| + | Please, also note that some features, like compression are considered to be legacy and expected to never be implemented in ovpn-dco. This is a design decision aimed at keeping ovpn-dco as simple as possible, while also taking the chance to drop those functionalities that are not consider useful anymore (or even harmful!). |
| + | |
| + | ## Supported features by platform |

| + | This table is constantly work in progress, therefore expect changes over time. |
