Yet being able to read and write to older partitions is a very important goal for ext3. EXT3 is actively developed and enhanced still, things like online resize, extended attributes, htree, extends etc are getting added over time. Some of those are entirely transparent, others have compatibility issues, there are several levels: 1) Entirely compatible (no special feature flag) 2) Read only compatible only 3) R/W compatible but clear the feature flags not understood (eg htree) 4) Compatible except on a fsck level 5) Entirely incompatible
