1.8.5

Protocol-Change:
    Added bundle validity rules - check that bundles confirm only tails and 2 bundles at most (#1786)
    Check validity rules on tip-sel and check-consistency only (#1802)


1.8.4

Hotfix: Ensure proper creation of solid entrypoints (#1702)

1.8.3

There is an edge case where IRI didn't account for a transaction that was shared between two distinct bundles.
Once it marked it as "counted" in one bundle, it was ignored for the next bundle. This lead to a corrupt ledger state.

Hotfix: Gyros - take transaction reattachments into account (#1699)

1.8.2

Change: The alpha value is now 0 by default, streamlining the tip selection process which will reduce memory and cpu load. This is done by skipping cumulative weight calculations. (Issue #1567)

Documentation: Fix broken link of online documentation (#1623)
Documentation: Update README.md (#1617)

    DNS_RESOLUTION_ENABLED
  * The following configuration options are added:
    NEIGHBORING_SOCKET_ADDRESS— defines the socket address to bind the TCP socket to.
    NEIGHBORING_SOCKET_PORT— defines the port of the TCP socket to use.
    RECONNECT_ATTEMPT_INTERVAL_SECONDS— defines the interval at which to try to reconnect/disconnect wanted neighbors.
    AUTO_TETHERING_ENABLED — controls auto-tethering, this was previously controlled via TESTNET true, default is false (also in testnet mode).
    MAX_NEIGHBORS— rename of MAX_PEERS, defines the max number of connected neighbors.
