What's new in Redis 3.0 compared to Redis 2.8?

Redis Cluster: a distributed implementation of a subset of Redis.
New "embedded string" object encoding resulting in less cache misses. Big speed gain under certain work loads.
AOF child -> parent final data transmission to minimize latency due to "last write" during AOF rewrites.
Much improved LRU approximation algorithm for keys eviction.
WAIT command to block waiting for a write to be transmitted to the specified number of slaves.
MIGRATE connection caching. Much faster keys migraitons.
MIGARTE new options COPY and REPLACE.
CLIENT PAUSE command: stop processing client requests for a specified amount of time.
BITCOUNT performance improvements.
CONFIG SET accepts memory values in different units (for example you can use "CONFIG SET maxmemory 1gb").
Redis log format slightly changed reporting in each line the role of the instance (master/slave) or if it's a saving child log.
INCR performance improvements.
