Changes - Additions - Known Issues

Description	Workaround	Ticket
New ledger serialization is supported and Leveldb is used as a storage for all ledgers : msgpack is used for the ledger serialization (both transaction log and merkle tree).
The new serialization change created changes to the directory structure for the nodes. The directory name changes are located on a node under .sovrin/data/nodes/<node name>/<directories>. The change removes the ledger files as plain text files and creates them as binary files. A new tool was created to view the ledger entries called read_ledger. This tool also provides you with a count of the transactions. To learn more about this tool and to see a list of available commands, run this as the sovrin user: read_ledger --h
Genesis transaction files are renamed adding a _genesis to the end of each file name.
Added the commands to the POOL_UPGRADE to support downgrade and re-installation. However both have issues and should not be used at this time.		INDY-735 INDY-755
Fixes to upgrade procedure, in particular an issue which caused an infinite loop.		INDY-316
A new CLI command was added to ease the process of rotating a verification key (verkey). The command is change current key or change current key with seed xxxxx.
Improvements to log messages.
In your sources.list you only need the entry "deb https://repo.evernym.com/deb xenial stable".
Implemented a command line tool to provide validator status.		INDY-715
"Debug" mode for tests was moved to parameter.		INDY-716
Log levels were changed on some debug level messages to an info level.		INDY-800
If the pool loses enough nodes and cannot reach consensus when enough nodes become available, the pool will still not reach consensus.	If you restart all the nodes in the pool, it will start reaching consensus again.	INDY-849
