>> # New Admin Interface

>> CouchDB 2.0 comes with a completely rewritten administration interface

>> # Performance

>> Both the replicator and compactor have undergone significant performance

>> well as PouchDB (https://pouchdb.com/) and Couchbase Lite instances.
>>
>> Compaction can now be run at any time, even continuously, with an 
>> i/o-queueing system ensuring that live requests are not slowed down while 
>> compaction is running.
>>
>> In addition: the compaction process is shorter, uses less CPU and RAM, 
>> produces smaller database files and freshly compacted databases are 
>> significantly faster to read from.
