-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.
-* 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?
 
 KNOWN BUGS
 ==========
@@ -44,4 +54,21 @@ KNOWN BUGS
     What happens if between 1 and 2 for some reason (system under huge load
     or alike) too many time passes? We should prevent expires while the
     AOF is loading.
+* #519: Slave may have expired keys that were never read in the master (so a DEL
+  is not sent in the replication channel) but are already expired since
+  a lot of time. Maybe after a given delay that is undoubltly greater than
+  the replication link latency we should expire this key on the slave on
+  access?
 
+DISKSTORE TODO
+==============
+
+* Fix FLUSHALL/FLUSHDB: the queue of pending reads/writes should be handled.
+* Check that 00/00 and ff/ff exist at startup, otherwise exit with error.

+* Fix DBSIZE to really do something interesting
+* Add a DEBUG command to check if an entry is or not in memory currently
+* dscache.c near 236, kobj = createStringObject... we could use static obj.
