  • [new] add additional Prometheus instrumentation across various functions
  • [new] add new API calls "admin-block", "factoid-block", "entrycredit-block" which output unmarshaled versions of those blocks
  • [new] add "ack" api call which takes a ChainID, setting the stage to accommodate nodes that only download some chains

Release notes for v0.4.2.5

  • [new] Added 'current-minute' API to check status of factomd node, enabling faster detection of stalls
  • [new] Added addresses of inputs and outputs of factoid transactions to 'pendingtransactions' API and factom-cli call
  • [new] Better logging infrastructure for debugging at scale
  • [fix] Stop leaders from stalling when restarting after a fault

Release notes for v0.4.2.4

  • [fix] Don't save unverified ancillary data received from a misbehaving peer
  • [new] Create utility to fix corrupted database chain heads
  • [fix] Immediately flush DBstates that will never become valid
  • [fix] Improve order of operations when saving DBstates with an incomplete process list

Release notes for v0.4.2.3

  • [Fix] Fixed a bug which prevented nodes from processing messages following initial blockchain download.
  • [Fix] Speedup boot while synching by ignoring messages which won't affect the state.
  • [Fix] Now discard dbsig messages which will never become valid, and handle potential collisions better.
  • [Fix] Handle EOM messages better with an invalid signature.
  • [New] Chain creation in wallet API now no longer forces user calculation of the ChainID.
  • [New] Add more historical checkpoints.
  • [New] Protect users from paying too many entry credits for an entry.

Release notes for v0.4.2.2

  • Fast bootup mode is now enabled by default. Factomd will complete the startup process faster after booting with a previously downloaded blockchain. (To disable this feature, start factomd with -fast=false)
  • The P2P connection is now less likely to be dropped with low numbers of peers.
  • Entry acknowledgement feedback is now more likely to succeed between minute 0 and 1 of block creation.
  • Chain creation acknowledgement feedback is now more likely to give timely results
  • More instrumentation of the API accessors
  • more fidelity of loading metrics from the database

Release notes for v0.4.2.1

  • This is a feature preview of the fast bootup mode.
  • Upgrade is only needed to try the new mode.
  • With this version, when booting after downloading the blockchain, factomd will save most of the work it does when starting. When starting again, it will fully startup much faster.
  • To try, start with this command factomd -fast=true
  • This release does not include any bugfixes beyond what fixed.

Release notes for v0.4.2.0

  • Better discovery of the highest block.
  • Catches up to highest block more quickly from 1-2 blocks behind.
  • Fix some bugs in process list handling.
  • Allow to download past block 87623. Older versions will likely get stuck.

Release notes for v0.4.1.3

  • Fix bug where block height stays 1-3 block behind servers for an extended period of time.
  • Fix bug where client can lose synchronization with the servers.
  • Fixed bug where data was downloaded then ignored/deleted.

Release notes for v0.4.1.2

  • This improves some network message management.
  • Improve handling of entries over the p2p network
  • Added some instrumentation

Release notes for v0.4.1.1

  • This fixes a problem which causes network disconnections when many peers are connecting to a node.
  • Increase the broadcast rate of p2p messages

Release notes for v0.4.1.0

This is a required upgrade. Older versions of software will not download new blocks from the network.

  • Large fix for network connection problems
  • Prioritized Directory Block and Factoid Block downloading over Entry downloading. This is apparent when viewing the control panel 1st and 2nd pass.
  • Limitations on outgoing peers
  • reduce outgoing message traffic
  • add computed balance messaging to prevent out-of sync balances (thanks to 34ro for reporting the error)
  • add prometheus logging for nice graphana performance graphs
  • expose API for checking leader status
  • add API call to get network transaction rate
  • Database consistency fixes
  • updated leveldb to include upstream fixes

Known issues:

  • If an earlier version of factomd was run, it may have corrupted your local database. If you are seeing panics as you are booting the latest factomd, the safest fix is to delete (or rename) your ~/.factom/m2/main-database folder
  • On machines with 4GB or less of RAM, memory spikes have been observed which cause the OS to stop factomd while downloading the blockchain.

Release notes for v0.4.0.3

  • This latest update fixes some consistency bugs. It is more aggressive in filling in gaps introduced when synching the blockchain with marginal network connections. This fixes some problems people were seeing with missing entries. (factoid transactions did not fall under this bug)
  • This updates to Golang 1.8, which gives better garbage collection.
  • Added some stabilization of the network connectivity.

Release notes for

  • Resolve "too many files" error

On Linux and Mac, factomd would crash due to using too many open files. This bug has been solved, and factomd no longer needs the adjust the ulimit in order to work.

  • Resolve Windows Database Problem

Enterprise Wallet and factom-walletd on some Windows systems would not cache factoid transactions. This solves the User Map Restriction bug.

  • Networking more Resiliant

Timeouts for network connections have been increased. This gives an incremental improvement for some stalling problems that factomd nodes have been seeing.

  • Lower CPU usage

Idle time CPU usage has been decreased for times after factomd boot and syncs.

  • Right Click in Wallet

Now the Enterprise Wallet supports right clicking for copy/pasting etc.

General Notes

factomd is much slower to start on a spinning hard drive, compared to a solid state drive. It is recommended to save the blockchain on a solid state drive.

You can’t perform that action at this time.
