Redis uses a standard practice for its versioning: major.minor.patchlevel. An even minor marks a stable release, like 1.2, 2.0, 2.2, 2.4, 2.6, 2.8. Odd minors are used for unstable releases, for example 2.9.x releases are the unstable versions of what will be Redis 3.0 once stable.
Stable (3.2)Redis 3.2 contains significant changes to the API and implementation of Redis. A new set of commands for Geo indexing was added (GEOADD, GEORADIUS and related commands). The new BITFIELD command handles contiguous arrays of integers or counters of arbitrary bits width and offset inside strings. Memory optimizations to hold the same data in less memory. Lua scripts can now contain side effects using the new effect replication. A complete remote Lua debugger is available in order to make writing scripts a simpler task. Read the release notes for the full set of changes.
Beta (4.0)Redis 4.0 finally reached Release Candidate status. Contains big improvements like: a modules system, PSYNC2 that allows to partially resynchronize with promoted slaves, Last Frequently Used (LFU) caching eviction policy, non blocking variants of DEL and FLUSH commands, a new memory debugging command (MEMORY), online memory defragmentation and more.
UnstableThis is where all the development happens. Only for hard-core hackers. Use only if you need to test the latest features or performance improvements. This is going to be the next Redis release in a few months.
Old (3.0)Redis 3.0 introduces Redis Cluster, a distributed implementation of Redis with automatic data sharding and fault tolerance, important speed improvements under certain workloads, improved AOF rewriting, and more.

*OtherHistorical downloads are still available on Google Code.
Scripts and other automatic downloads can easily access the tarball of the latest Redis stable version at http://download.redis.io/redis-stable.tar.gz. The source code of the latest stable release is always browsable here, use the file src/version.h in order to extract the version in an automatic way.
*How to verify files for integrity
The Github repository redis-hashes contains a README file with SHA1 digests of released tarball archives. Note: the generic redis-stable.tar.gz tarball does not match any hash because it is modified to untar to the redis-stable directory.
