v2.0.0b1

Fixed

• Fixed a bug that arose with some code that treated transactions-waiting-for-block-inclusion as if they were already stored in MongoDB (i.e. already in a block). Pull request #2318
• If a user asked for a block and it happened to be an empty block, BigchainDB returned 404 Not Found, as if the block did not exist. Now it returns a 200 OK with a block containing no transactions, i.e. an empty block. Pull request #2321

Known Issues

• An issue was found with the bigchaindb upsert-validator command. A solution was proposed in BEP-19 and is being implemented in pull request #2314
• If you run BigchainDB locally using make start (i.e. using Docker Compose) and then you put the node under heavy write load, Tendermint can become unresponsive and running make stop can hang.
• There seems to be one or more issues with Tendermint when it is put under heavy load (i.e. even when BigchainDB isn't involved). See Tendermint issues #1394, #1642 and #1661

Notes

• There's a new docs page about how to set up a network where each node uses a single virtual machine.
• We checked, and BigchainDB 2.0 Beta 1 works with MongoDB 3.6 (and 3.4).
• Support for RethinkDB is completely gone.
