**WARNING: THIS IS AN UNSTABLE DEVELOPMENT VERSION**
22
23
Current limitation include:
24
25
* Metadata format is not stable yet -- you may need to
26
discard history in the future.
27
28
* Insufficient error handling.
29
30
* Many commands unimplemented or partially implemented.
31
32
* Space-inefficient storage.
33
34
* No merge operators yet.
