 Database Format
 ===============
 
-The database and metadata format of ElectrumX is very likely to change
-prior to 1.0 release.  Existing DBs will not be unusable and you will
-need to resync from Genesis, which is quite tolerable.

 ChangeLog
 =========
 
+Version 0.10.0
+--------------
+
+Major rewrite of DB layer as per issue `#72`_.  UTXOs and history are
+now indexed by the hash of the pay to script, making the index
+independent of the address scheme.  The history and UTXO DBs are also
+now separate.
+
+Together these changes reduce the size of the DB by approximately 15%
+and the time taken to sync from genesis by about 20%.
+
+Note the **UTXO_MB** and **HIST_MB** environment variables have been
+removed and replaced with the single environment variable
+**CACHE_MB**.  I suggest you set this to 90% of the sum of the old
+variables to use roughly the same amount of memory.
+
+For now this code should be considered experimental; if you want
+stability please stick with the 0.9 series.
