-DISKSTORE TODO
-==============
 
-* Check that 00/00 and ff/ff exist at startup, otherwise exit with error.
-* Implement sync flush option, where data is written synchronously on disk when a command is executed.
-* Implement MULTI/EXEC as transaction abstract API to diskstore.c, with transaction_start, transaction_end, and a journal to recover.
-* Stop BGSAVE thread on shutdown and any other condition where the child is killed during normal bgsave.
-* Use a mutex to log on the file, so that we don't get overlapping messages, or even better make sure to use a single write against it.
-* Fix RANDOMKEY to really do something interesting
-* Fix DBSIZE to really do something interesting
-* Add a DEBUG command to check if an entry is or not in memory currently

-REPLICATION
+API CHANGES
 ===========
 
-* PING between master and slave from time to time, so we can subject the
-master-slave link to timeout, and detect when the connection is gone even
-if the socket is still up.
+* Turn commands into variadic versions when it makes sense, that is, when
+  the variable number of arguments represent values, and there is no conflict
+  with the return value of the command.
+
+APPEND ONLY FILE
+================
+
+* in AOF rewirte use HMSET to rewrite small hashes instead of multiple calls
+  to HSET.
 
 OPTIMIZATIONS
 =============
 
+* Avoid COW due to incrementing the dict iterators counter.
 * 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.
 * Read-only mode for slaves.
+* Redis big lists as linked lists of small ziplists?
+  Possibly a simple heuristic that join near nodes when some node gets smaller than the low_level, and split it into two if gets bigger than high_level.
+
+REPORTING
+=========
+
+* Better INFO output with sections.
+
+RANDOM
+======
+
+* Clients should be closed as far as the output buffer list is bigger than a given number of elements (configurable in redis.conf)
+* Should the redis default configuration, and the default redis.conf, just bind 127.0.0.1?
