This keeps the gocryptfs code base clean and maintainable. Users are encouraged to upgrade their filesystems (see below for how) as the new features often improve security. If this is not an option, they can stay on the `v0.x` branch which will continue to be supported for bug fixes. As seen on the table below, v1.0 will be the first version to drop support for very old filesystems (v0.6 and lower). @@ -11,4 +13,8 @@ As seen on the table below, v1.0 will be the first version to drop support for v | v0.5 | DirIV | - | Y | Y | Y | Y | Y | Y | - | | v0.6 | DirIV, EMENames | - | - | Y | Y | Y | Y | Y | - | | v0.7, v0.8 | DirIV, EMENames, GCMIV128 | - | - | - | Y | Y | Y | Y | Y | -| v0.9, v0.10, v1.0 | DirIV, EMENames, GCMIV128, LongNames | - | - | - | - | - | Y | Y | Y |
