1) Fixed the height field to store the height for both coinbase/non coinbase open outputs.

Browse Source 
2) Thanks to Ed Lee - Fixed Issue 447 : H2 store: block header hash code is off by 4 bytes. This fix also applies to Postgres and MySQL stores.
3) Added a coinbase field to the openoutputs table and updated code to use this value.
4) Updated field type of ‘value’ in the openoutputs table from bytes to long.
5) Updated the stores (DatabaseFullPrunedBlockStore) with a compatibility check.
6) Updated field type of ‘addresstargetable’ in the openoutputs table from int to tinyint/smallint.
