 Most of the features already implemented for this release. The following is a list of the missing things in order to release the first beta tar.gz:
 
-* Man pages for SRANDMEMBER, missing Z-commands, ...
-* Write docs for the "STORE" operaiton of SORT. Link to the article about SORT by written by defunkt.
-* ZRANGEBYSCORE test, ZRANGEBYSCORE LIMIT option.
-* Sorted sets infinity tests.
+* When Redis runs as slave make sure to set the fake client it uses to talk to the master as c->authenticated = 1 to avoid problems with slaves with requirepassword set.
+* Document BGREWRITEAOF.
 
 VERSION 1.4 TODO (Hash type)
 ============================
 
+* Blocking LPOP (BLPOP).
 * Hashes (HSET, HGET, HEXISTS, HLEN, ...).
-* An utility able to export an .rdb file into a text-only JSON dump, we can't live anymore without such a tool. Probably an extension to redis-cli.
+* List ops like L/RPUSH L/RPOP should return the new list length.
 
 VERSION 1.6 TODO (Virtual memory)
 =================================
@@ -43,16 +42,44 @@ VERSION 2.2 TODO (Optimizations and latency)
 
 * JSON command able to access data serialized in JSON format. For instance if I've a key foobar with a json object I can alter the "name" file using somthing like: "JSON SET foobar name Kevin". We should have GET and INCRBY as well.
 
+OTHER IMPORTANT THINGS THAT WILL BE ADDED BUT I'M NOT SURE WHEN
+===============================================================
+
+BIG ONES:
+
+* Specially encoded memory-saving integer sets.
+* A command to export a JSON dump (there should be mostly working patch needing major reworking).
+
+SMALL ONES:
+
+* Give errors when incrementing a key that does not look like an integer, when providing as a sorted set score something can't be parsed as a double, and so forth.
+* MSADD (n keys) (n values). See this thread in the Redis google group: http://groups.google.com/group/redis-db/browse_thread/thread/e766d84eb375cd41
+
 SHORT/LONG TERM RANDOM TODO ITEMS
 =================================
 
- * FORK command (fork()s executing the commands received by the current
-   client in the new process). Hint: large SORTs can use more cores,
-   copy-on-write will avoid memory problems.
- * SORT: Don't copy the list into a vector when BY argument is constant.
- * Write the hash table size of every db in the dump, so that Redis can resize the hash table just one time when loading a big DB.
- * LOCK / TRYLOCK / UNLOCK as described many times in the google group
- * Replication automated tests
- * BYTEDARRAY type
- * zmalloc() should avoid to add a private header for archs where there is some other kind of libc-specific way to get the size of a malloced block.
- * Read-only mode.
+Most of this can be seen just as proposals, the fact they are in this list
+it's not a guarantee they'll ever get implemented ;)
+
+* Move dict.c from hash table to skip list, in order to avoid the blocking resize operation needed for the hash table.
+* FORK command (fork()s executing the commands received by the current
+  client in the new process). Hint: large SORTs can use more cores,
+  copy-on-write will avoid memory problems.
+* DUP command? DUP srckey dstkey, creates an exact clone of srckey value in dstkey.
+* SORT: Don't copy the list into a vector when BY argument is constant.
+* Write the hash table size of every db in the dump, so that Redis can resize the hash table just one time when loading a big DB.
+* LOCK / TRYLOCK / UNLOCK as described many times in the google group
+* Replication automated tests
+* Byte Array type (BA prefixed commands): BASETBIT BAGETBIT BASETU8 U16 U32 U64 S8 S16 S32 S64, ability to atomically INCRBY all the base types. BARANGE to get a range of bytes as a bulk value, BASETRANGE to set a range of bytes.
+* zmalloc() should avoid to add a private header for archs where there is some other kind of libc-specific way to get the size of a malloced block. Already done for Mac OS X.
+* Read-only mode.
+* Pattern-matching replication.
+* Don't save empty lists / sets / zsets on disk with snapshotting.
+* Remove keys when a list / set / zset reaches length of 0.
+
+DOCUMENTATION WISHLIST
+======================
+
+* Page explaining tips to reduce memory usage.
+* A Sorted sets HOWTO
