Nimbus `v1.4.2` - "Upgrade procedure: Hotfix release"
|
|
|
|
This release is marked as `low-urgency` for all Nimbus users other than those who have recently updated to `v1.4.1` from a version earlier than `v1.1.0` - for these users this is a `high-urgency` release.
|
|
|
|
## Notable changes
|
|
This release fixes an issue in the upgrade procedure when upgrading from a version earlier than `1.1.0` to `1.4.x`.
|
|
|
|
**How can I tell if I've been affected?**
|
|
|
|
If you've already upgraded to `1.4.1`, you can tell that you've been affected if you're seeing the following` WRN log`:
|
|
|
|
```
|
|
Received invalid sequence of blocks
|
|
```
|
|
|
|
To re-iterate, this issue only affects users who are upgrading from `1.0.12` or earlier (released on `2021-03-10`), **and have not run any release in between**. Everyone else can ignore this release.
|
|
|
|
|
|
2021-07-10 v1.4.1
|
|
=================
|
|
|
|
Nimbus v1.4.1 - "Every attestation counts"
|
|
|
|
This release is marked as `low-urgency`
|
|
|
|
## Notable changes
|
|
|
|
Nimbus `v1.4.0` users might have noticed that they are missing a small number of (seemingly random) attestations since the update. Our investigation into the matter has showed that, due to `v1.4.0`'s significant performance improvements, Nimbus validators occasionally send their first attestation for a new epoch before some peers are ready. These "slow" peers end up dropping early attestations because they're busy with the epoch transition.
|
|
|
|
It's a rare occurrence, since it requires a validator to be scheduled to attest in the first slot of an epoch *and* for the beacon node to only be connected to "slow" peers for the respective libp2p topic. If both these conditions are true, a premature attestation may be lost in time, like tears in the rain.
|
|
|
|
As a fix, we are using a larger send delay: [#2705](https://github.com/status-im/nimbus-eth2/pull/2705).
|
|
|
|
Fo those Nimbus `v1.4.0` users who are concerned about reaching optimal attestation effectiveness, we encourage you to upgrade as soon as possible.
|
|
|
|
Other changes include log flushing and metrics fixes.
|
|
|
|
Full list:
|
|
- increase attestation wait time ([#2705](https://github.com/status-im/nimbus-eth2/pull/2705))
|
|
- ensure logs are printed without delays ([#2669](https://github.com/status-im/nimbus-eth2/pull/2669))
|
|
- fix metrics on Windows ([#2707](https://github.com/status-im/nimbus-eth2/pull/2707))
|
|
|
|
|
|
2021-06-21 v1.4.0
|
|
=================
|
|
|
|
This release is marked as low-urgency - please update at your convenience.
|
|
|
|
It contains **improvements to attestation effectiveness and CPU usage**.
|
|
|
|
It also contains **improvements to the RPC APIs**, as suggested by DappNode and RocketPool, and in preparation for our refactored validator client.
|
|
### Outdated Nimbus instances
|
|
|
|
A reminder that if you're running Nimbus with a version prior to `1.0.10` (March 2021) you are exposed to a vulnerability in our core cryptography library (this library is used by all eth2 clients). See this [blst security advisory](https://github.com/supranational/blst/security/advisories/GHSA-x279-68rr-jp4p) for more information. If this concerns you, please update as soon as you can.
|
|
|
|
## Notable changes
|
|
### We've added:
|
|
|
|
* Nightly builds for the very adventurous. (https://github.com/status-im/nimbus-eth2/pull/2640)
|
|
* We expect users of nightly builds to be comfortable providing debugging logs.
|
|
|
|
### We've fixed:
|
|
|
|
* RPC API endpoints (https://github.com/status-im/nimbus-eth2/pull/2585, https://github.com/status-im/nimbus-eth2/pull/2586)
|
|
* `/eth/v1/beacon/pool/attestations`
|
|
* `/api/eth/v1/validator/aggregate_and_proofs`
|
|
* Doppelganger detection: fixed false positive on fast restart (https://github.com/status-im/nimbus-eth2/pull/2656/)
|
|
|
|
|
|
### We've improved
|
|
|
|
* Database read performance improvements during epoch transitions and startup (https://github.com/status-im/nimbus-eth2/pull/2639, https://github.com/status-im/nimbus-eth2/pull/2617)
|
|
* Better usage of caches, specially when validating attestations (https://github.com/status-im/nimbus-eth2/pull/2631)
|
|
|
|
|
|
2021-05-17 v1.3.0
|
|
=================
|
|
|
|
This release offers safer and easier options to migrate to Nimbus from other clients.
|
|
It also brings further performance optimizations.
|
|
|
|
**We've added:**
|
|
|
|
* A new `slashingdb` sub-command with `import` and `export` options. This allows for
|
|
safely migrating to Nimbus from another client (as per the [EIP-3076](https://eips.ethereum.org/EIPS/eip-3076)
|
|
slashing protection interchange format).
|
|
Please see the the newly prepared [migration guides](https://nimbus.guide/migration.html) for the details.
|
|
|
|
* A new `ncli_db validatorPerf` command. This can be used to perform a textual
|
|
report for the attestation performance of a particular validator
|
|
(please note that `ncli_db` is available only when compiling from source).
|
|
|
|
* Official binaries for macOS (AMD64 and ARM64).
|
|
|
|
* Pruning of the slashing protection database and a transition to more optimal
|
|
queries. This results in a significant reduction in both disk and CPU usage
|
|
on nodes running a large number of validators.
|
|
|
|
* More consistent level of validation for the attestations received from
|
|
third-party sources and the JSON-RPC and REST APIs. This prevents invalid
|
|
attestations from being broadcasted to the network.
|
|
|
|
* Performance tuning of attestation subnet transition timings and state
|
|
snapshotting intervals. This results in improved CPU and bandwidth usage.
|
|
|
|
**We've fixed:**
|
|
|
|
* Problems in the GossipSub subnet walking logic leading to unnecessary bandwidth
|
|
and CPU costs.
|
|
|
|
|
|
2021-05-03 v1.2.2
|
|
=================
|
|
|
|
This is a bugfix release improving the stability of the REST API and addressing
|
|
issues discovered during the mainnet deposit processing accident of 24-25 April.
|
|
|
|
**New features:**
|
|
|
|
* More efficient attestation processing pipeline using less queuing.
|
|
|
|
**We've fixed:**
|
|
|
|
* Insufficient validation of third-party Eth1Data votes.
|
|
|
|
* Sporadic REST API connection interruptions resulting from large request or
|
|
result payloads.
|
|
|
|
* Incorrectly sent empty GossipSub IWANT messages.
|
|
|
|
|
|
2021-04-20 v1.2.1
|
|
=================
|
|
|
|
This is a hotfix release that solves the database migration issue highlighted
|
|
in the previous release -- this problem affected new Nimbus users who used
|
|
v1.1.0 to sync with the network from genesis, essentially resetting their
|
|
state database and causing them to start re-syncing from genesis.
|
|
|
|
If you have used an older version of Nimbus prior to upgrading to v1.1.0,
|
|
you should not be affected.
|
|
|
|
If you were affected, you have a couple of options available to you:
|
|
|
|
1) If you have backed-up your database prior to upgrading to v1.2.0, you
|
|
can restore the database from backup and execute the migration successfully
|
|
after upgrading to this release.
|
|
|
|
2) If you haven't backed up your database, you can upgrade to this release at
|
|
your convenience; rest assured it won't delete your sync history.
|
|
|
|
Please accept our sincerest apologies for any inconvenience we may have caused.
|
|
We are reviewing our release testing policies to ensure that we cover a greater
|
|
number of possible upgrade paths going forward.
|
|
|
|
|
|
2021-04-19 v1.2.0
|
|
=================
|
|
|
|
If [`v1.1.0`](https://github.com/status-im/nimbus-eth2/releases/tag/v1.1.0)
|
|
was the big I/O update, `v1.2.0` is all about the CPU - together, these
|
|
updates help secure Nimbus against future network growth, and provide us
|
|
with a higher security margin and substantial [profitability improvements]
|
|
(https://twitter.com/ethnimbus/status/1384071918723092486).
|
|
|
|
To highlight just one data point, CPU usage has been cut by up to 50% over
|
|
v1.1.0 ( 🙏 batched attestation processing). This makes it the first release
|
|
we can officially recommend for validating on a Raspberry Pi 4.
|
|
|
|
> **N.B.** this release contains a **critical stability fix** so please
|
|
**make sure you upgrade!**
|
|
|
|
**New features:**
|
|
|
|
* Beta support for the official Beacon Node REST API:
|
|
https://ethereum.github.io/eth2.0-APIs/. Enable it by launching
|
|
the client with the `--rest:on` command-line flag
|
|
|
|
* Batched attestation verification and other reforms **->** massive
|
|
reduction in overall CPU usage.
|
|
|
|
* Improved attestation aggregation logic **->** denser aggregations
|
|
which in turn improve the overall health of the network and improve
|
|
block production.
|
|
|
|
* More efficient LibP2P connection handling code **->** reduction in
|
|
overall memory usage.
|
|
|
|
**We've fixed:**
|
|
|
|
* A critical stability issue in attestation processing.
|
|
|
|
* `scripts/run-*-node.sh` no longer prompts for a web3 provider URL
|
|
when the `--web3-url` command-line option has already been specified.
|
|
|
|
|
|
2021-04-05 v1.1.0
|
|
=================
|
|
|
|
This release brings planned reforms to our database schema that provide
|
|
substantial performance improvements and pave the way for an an improved
|
|
doppelganger detection ready immediately to propose and attest to blocks
|
|
(in a future release).
|
|
|
|
Please be aware that we will remain committed to maintaining backwards
|
|
compatibility between releases, but **this release does not support
|
|
downgrading back to any previous 1.0.x release**.
|
|
|
|
As a safety precaution, we advise you to **please backup your Nimbus
|
|
database before upgrading** if possible.
|
|
|
|
**New features:**
|
|
|
|
* More efficient state storage format ==> reduced I/O load and lower
|
|
storage requirements.
|
|
|
|
* More efficient in-memory cache for non-finalized states ==> significant
|
|
reduction in memory usage.
|
|
|
|
* More efficient slashing database schema ==> scales better to a larger
|
|
number of validators.
|
|
|
|
* The metrics support is now compiled by default thanks to a new and
|
|
more secure HTTP back-end.
|
|
|
|
* Command-line tools for generating testnet keystores and JSON deposit
|
|
files suitable for use with the official network launchpads.
|
|
|
|
* `setGraffiti` JSON-RPC call for modifying the graffiti bytes of the
|
|
client at run-time.
|
|
|
|
* `next_action_wait` metric indicating the time until the next scheduled
|
|
attestation or block proposal.
|
|
|
|
* More convenient command-line help messages providing information
|
|
regarding the default values of all parameters.
|
|
|
|
* `--direct-peer` gives you the ability to specify gossip nodes
|
|
to automatically connect to.
|
|
|
|
* Official docker images for ARM and ARM64.
|
|
|
|
* Support for fallback `--web3-url` providers.
|
|
|
|
**We've fixed:**
|
|
|
|
* Long processing delays induced by database pruning.
|
|
|
|
* File descriptor leaks (which manifested after failures of the selected
|
|
web3 provider).
|
|
|
|
* The validator APIs now return precise actual balances instead of rounded
|
|
effective balances.
|
|
|
|
* A connection tracking problem which produced failed outgoing connection
|
|
attempts.
|
|
|
|
**Breaking changes:**
|
|
|
|
* Nimbus-specific JSON-RPCs intended for debug purposes now have
|
|
the `debug_` prefix:
|
|
|
|
- `getGossipSubPeers` is now `debug_getGossipSubPeers`
|
|
- `getChronosFutures` is now `debug_getChronosFutures`
|
|
|
|
|
|
2021-03-10 v1.0.12
|
|
==================
|
|
|
|
This is bugfix release correcting an error in the Prater testnet config
|
|
leading to incorrect Eth1 voting.
|
|
|
|
|
|
2021-03-10 v1.0.11
|
|
==================
|
|
|
|
This is a minor release adding support for connecting to the Prater testnet.
|
|
|
|
|
|
2021-03-10 v1.0.10
|
|
==================
|
|
|
|
This release contains important security and performance improvements.
|
|
|
|
-----
|
|
|
|
**Upgraded:**
|
|
|
|
* We're now running version 0.3.3 of the BLST library:
|
|
https://github.com/supranational/blst/releases/tag/v0.3.3
|
|
|
|
* We've switched to a more recent version of BearSSL
|
|
(this version features a more up-to-date list of trusted root certificates)
|
|
|
|
* We're now consistent with the v1.0.1 Eth2 spec
|
|
|
|
**We've fixed:**
|
|
|
|
* A frequent crash occurring on certain hardware configurations after
|
|
building Nimbus from source.
|
|
|
|
* Long processing delays triggered by the reception of attestations that
|
|
reference already pruned states.
|
|
|
|
* LibP2P peer management issue which led to an accumulation of inactive
|
|
connections.
|
|
|
|
* A false-positive in doppelganger detection triggered by rebroadcasted
|
|
older attestations arriving with a significant delay.
|
|
|
|
**New features**:
|
|
|
|
* A new improved format of the slashing protection database:
|
|
|
|
- Significantly reduces the disk load with a large number of validators (1000+).
|
|
|
|
- Makes it possible to enhance our doppelganger detection in the future
|
|
such that waiting for 2 epochs before attesting is not necessary.
|
|
|
|
To ensure smooth upgrade and emergency rollback between older and future
|
|
Nimbus versions, v1.0.10 will keep track of your attestation in both the
|
|
old and the new format. The extra load should be negligible for home
|
|
stakers.
|
|
|
|
|
|
2021-03-09 v1.0.9
|
|
=================
|
|
|
|
This version was an internal release candidate build for the 1.0.10 release.

|
2021-02-22 v1.0.8
|
|
=================
|
|
|
|
This release includes important JSON-RPC stability improvements
|
|
and compatibility fixes, which make it possible to use Nimbus
|
|
as a RocketPool operator.
|
|
|
|
-----
|
|
|
|
**New features:**
|
|
|
|
* RocketPool integration:
|
|
see https://github.com/rocket-pool/smartnode/pull/89
|
|
and https://github.com/rocket-pool/smartnode-install/pull/26/commits/da720acc8f4c1c31c05971748fbc144de1621830
|
|
|
|
* Next attestation time displayed on every "Slot end" log message
|
|
(helps you select the best time for restarting the node)
|
|
|
|
* libp2p scoring: disconnect from badly performing peers and prioritise
|
|
peers with better latency and throughput.
|
|
|
|
**We've fixed:**
|
|
|
|
* A rare crash triggered when connecting to a web3 provider using
|
|
a secure web socket.
|
|
|
|
* JSON-RPC spec violations and potential DoS attack vectors.
|
|
|
|
* Two stale bootstrap node addresses.
|
|
|
|
|
|
2021-02-04 v1.0.7
|
|
=================
|
|
|
|
A release which provides additional protection against accidental slashings
|
|
and further performance improvements across the board.
|
|
|
|
-----
|
|
|
|
**New features:**
|
|
|
|
* New slashing protection mechanism (doppelganger detection) prevents your
|
|
validator from contradicting itself if you have accidentally left it running
|
|
on another machine (see the `--doppelganger-detection` option).
|
|
|
|
* Optimized batching of BLS signature verification leading to faster sync
|
|
speeds and reduced CPU load.
|
|
|
|
* Further improvements to attestation subnet walking resulting in a reduction
|
|
in both bandwidth and CPU usage.
|
|
|
|
* A new `--subscribe-all-subnets` option allowing the node to maintain peers
|
|
from all attestation subnets (most suitable for bootstrap nodes).
|
|
|
|
* Official docker images published at https://hub.docker.com/r/statusim/nimbus-eth2
|
|
|
|
* Official Windows binaries created from a reproducible build recipe.
|
|
|
|
* An option to enable the automatic updating of IP:Port in the ENR
|
|
(off by default, specify `--enr-auto-update:true` to turn it on)
|
|
|
|
**We've fixed:**
|
|
|
|
* A bug that had the potential to completely halt all syncing activity.
|
|
|
|
* Inefficient processing of blocks with Eth1 deposits which occassionally
|
|
led to increased latencies when delivering attestations.
|
|
|
|
* Outdated records in our bootstrap nodes list.
|
|
|
|
* An Eth1 syncing issue which manifested itself as a "Corrupted deposits
|
|
history detected" error.
|
|
|
|
* Non-standard encoding of certain data types such as signatures and bit
|
|
sequences within the results of JSON-RPC requests.
|
|
|
|
**We've deprecated:**
|
|
|
|
* `make beacon_node` will no longer compile the beacon node.
|
|
You'll need to run `make nimbus_beacon_node` from now on
|
|
|
|
* On monday we'll phase out the old `master` branch. If you're still building
|
|
Nimbus from `master`, please switch to `stable`.
|
|
|
|
|
|
2021-01-10 v1.0.6
|
|
=================
|
|
|
|
A release that brings reproducible precompiled binaries for ARM devices and
|
|
significant performance improvements.
|
|
|
|
-----
|
|
|
|
**New features:**
|
|
|
|
* Reproducible build recipe for creating Nimbus Linux binaries intended for
|
|
ARM devices.
|
|
|
|
* Improved attestation subnet walking logic: this brings significant reductions
|
|
in bandwidth usage and CPU load.
|
|
|
|
* Better usage of the Sqlite3 checkpointing API (minor performance improvement).
|
|
|
|
* Larger window for the candidate attestations included in blocks: this can lead
|
|
to higher block rewards.
|
|
|
|
**We've fixed:**
|
|
|
|
* Incorrect `attnets` value announced in ENR records.
|
|
|
|
|
|
2021-01-09 v1.0.5
|
|
=================
|
|
|
|
The 1.0.5 release was retracted because it included a potential optimization
|
|
to the reproducible build scripts that turned out to create a buggy binary for
|
|
AMD64 systems. Manually built binaries through the Makefiles were not affected.
|
|
After fixing the problem, the release was re-published as 1.0.6 with the same
|
|
release notes.
|
|
|
|
|
|
2020-12-16 v1.0.4
|
|
=================
|
|
|
|
A release bringing further stability improvements and minor performance
|
|
optimisations.
|
|
|
|
-----
|
|
|
|
**New features:**
|
|
|
|
* Nimbus can now be safely shut down with the SIGTERM signal on POSIX systems.
|
|
|
|
* New discovery IP limits making theoretic eclipse attack much more costly.
|
|
|
|
* A new `make benchmarks` target for obtaining a performance score for your system.
|
|
|
|
* Upgrade of the BLST library bringing minor performance improvement.
|
|
|
|
**We've fixed:**
|
|
|
|
* Gossipsub resource leaks that may reduce the quality of the gossipsub mesh and
|
|
reduce the attestation effectiveness of the client.
|
|
|
|
* Incomplete validation of the forwarded attestations that may affect negatively
|
|
the peer score of Nimbus.
|
|
|
|
* An issue halting the activity of the Eth1 monitor.
|
|
|
|
* The incorrect zero validator balance displayed while the node is syncing.
|
|
|
|
* A regression preventing Nimbus to be used with custom testnet metadata files.
|
|
|
|
|
|
2020-12-09 v1.0.3
|
|
=================
|
|
|
|
A release fixing issues that have contributed to Nimbus's lower peer scores
|
|
on the network.

|
|
**New features:**
|
|
|
|
* New metrics tracking the syncing progress of the Eth1 deposit contract
|
|
monitor.
|
|
|
|
* A new `web3 test` command for testing the compatibility of a web3 provider
|
|
before using it.
|
|
|
|
**We've fixed:**
|
|
|
|
* Incorrect timing when sending aggregated attestations.
|
|
|
|
* Stale ENR records not taking into account the dynamic attestation subnet
|
|
hopping.
|
|
|
|
* An invalid error message produced by the `deposits exit` command (validator
|
|
state unknown).
|
|
|
|
|
|
2020-12-03 v1.0.2
|
|
=================
|
|
|
|
A release that fixes an issue regarding the occasional missed block proposal.
|
|
|
|
Proposing a block is arguably the most important duty you have as a validator.
|
|
So it's important you update at your earliest convenience.
|
|
|
|
-----
|
|
|
|
**New features:**
|
|
|
|
* 8 new JSON-RPC calls that bring us to feature parity with the official
|
|
beacon node API.
|
|
|
|
**We've fixed:**
|
|
|
|
* A deposit merkle proofs generation issue occasionally resulting in missed
|
|
block proposals shortly after a new Eth1 head was selected.
|
|
|
|
* Slow status bar updates in the absense of logging messages.
|
|
|
|
|
|
2020-12-02 v1.0.1
|
|
=================
|
|
|
|
A release with a number of important fixes and optimisations.
|
|
|
|
**Please update** at your earliest convenience.
|
|
|
|
In order to minimise downtime, we recommend updating and rebuilding
|
|
the beacon node **before restarting.**
|
|
|
|
-----
|
|
|
|
**New features:**
|
|
|
|
* More conservative Eth1 syncing requests to reduce the likelihood of
|
|
going over the maximum allowed burst rates under the Infura free plan
|
|
(predominantly aimed at those running Nimbus on resource-restricted
|
|
device like Raspberry Pi's) + more resiliency in case of errors.
|
|
|
|
**We've fixed:**
|
|
|
|
* A "Only one concurrent read allowed" crash reported by multiple users.
|
|
|
|
* An error in the default configuration preventing the node from discovering
|
|
peers on mainnet unless the `--network=mainnet` flag was passed. Please note
|
|
that this not affect users starting their node with the `./run-mainnet-beacon-node`
|
|
command.
|
|
|
|
* The fractional part of the ETH balance in the Nimbus status bar
|
|
(the value displayed should now be correct).
|
|
|
|
* An issue that occasionally caused the Eth1 syncing process to get stuck
|
|
before reaching the head of the chain.
|
|
|
|
* Unnecessary network traffic related to GossipSub `IHAVE`.
|
|
|
|
* Incorrect gossipsub pruning which occasionally resulted in messages
|
|
getting lost.
|
|
|
|
* An issue where an excessively long graffiti string could cause a crash on
|
|
startup.
|
|
|
|
* A Linux-only issue that resulted in the `deposits import` command ignoring
|
|
its supplied arguments.
|

2020-11-29 v1.0.0-stateofus
|
|
===========================
|
|
|
|
As promised, a slightly more polished release before Mainnet launch ✨
|
|
|
|
Please make sure you update to this release before Eth2 genesis this
|
|
Tuesday (December 1 12:00:23 UTC), as it contains some important improvements.
|
|
|
|
-----------------
|
|
|
|
**New features:**
|
|
|
|
* Updated list of bootstrap nodes for Mainnet.
|
|
|
|
* Prometheus metrics for validator balances. The beacon node will also
|
|
display the total balance of all attached validators in the status
|
|
footer by default.
|
|
|
|
* `deposits import` now automagically finds the `validator_keys` directory
|
|
produced by the `eth2.0-deposit-cli` if it is located in the same working
|
|
directory.
|
|
|
|
* A `deposits exit` command for submitting a voluntary validator exit.
|
|
|
|
* A `record` CLI command for inspecting and creating ENR records.
|
|
|
|
* An `--agent-string` option for specifying how Nimbus will present itself
|
|
in LibP2P messages. The default value is now `nimbus`.
|
|
|
|
* New RPC calls to track node and config status. Specifically, a JSON-RCP
|
|
call for inspecting the active config preset (`get_v1_config_spec`).
|
|
|
|
**We've fixed:**
|
|
|
|
* Inaccurate peer counts (an occasional mismatch between the number of
|
|
syncing peers and GossipSub peers) -- the default peer limit has been
|
|
increased to maintain a healthy gossip mesh.
|
|
|
|
* High bandwidth usage of GossipSub (due to sub-optimal caching and lack
|
|
of limits in the IWANT/IHAVE exchange messages) -- we're now using the
|
|
latest spec GossipSub parameters.
|
|
|
|
* High sync memory footprint -- we've reduced the number of sync workers
|
|
from 20 to 10 (note, this should not affect sync speed).
|
|
|
|
|
|
2020-11-25 v1.0.0-rc1
|
|
=====================
|
|
|
|
We're happy to join the other client teams in announcing our `v1.0.0` release
|
|
candidate with support for Mainnet ✨
|
|
|
|
You can use this release/binary to set up your rig and monitoring for Eth2
|
|
genesis next Tuesday (*December 1 12:00:23 UTC*).
|
|
|
|
> **N.B.** There will be at least one more release, before December 1st.
|
|
> In particular, **we are planning a more polished release for Sunday** which
|
|
> will act as a drop-in replacement for this release candidate.
|
|
|
|
Don't worry if your peer count appears low at first -- It should increase as
|
|
more validators connect to Mainnet.
|
|
|
|
-----------------
|
|
|
|
**Highlights include:**
|
|
|
|
* The addition of a deposit contract "state snapshot" to network metadata.
|
|
This allows the client to skip syncing deposits made prior to the snapshot.
|
|
|
|
* A much faster startup time. We've removed the deposits table from the database,
|
|
which means the client no longer needs to process all deposits on start-up.
|
|
|
|
* The Eth1 monitor no longer starts if the beacon node has zero validators attached to it.
|
|
|
|
* The genesis detection code is now optional and disabled by default.
|
|
|
|
* An RPC call to get Chronos futures at runtime.
|
|
|
|
* Eth2 spec gossip parameters.
|
|
|
|
**We've fixed:**
|
|
|
|
* A database corruption issue affecting Pyrmont nodes.
|
|
|
|
* Unnecessary copy/memory alloc when loading DbSeq entries.
|
|
|
|
* A block production issue affecting clients that hadn't finished downloading the latest deposits.
|
|
|
|
|
|
2020-11-20 v0.6.6
|
|
=================
|
|
|
|
**New features:**
|
|
|
|
* New RPC APIs for inspecting the internal state of the Eth1 monitor.
|
|
|
|
**We've fixed:**
|
|
|
|
* A fork-choice issue causing Nimbus to get stuck on a particular slot.
|
|
|
|
* A logic error causing Nimbus to vote for an incorrect Eth1 block.
|
|
|
|
* A crash during initialization when the web3 provider is refusing
|
|
to serve data (e.g. due to exceeded request quota).
|
|
|
|
|
|
2020-11-17 v0.6.4
|
|
=================
|
|
|
|
**New features:**
|
|
|
|
* Support for the Pyrmont testnet.
|
|
|
|
* The PCRE library is no longer necessary for building Nimbus.
|
|
|
|
* Sensitive files such as keystores are now accessible only to the
|
|
user of the beacon node on POSIX systems (the group rights have
|
|
been dropped).
|
|
|
|
**We've fixed:**
|
|
|
|
* An issue preventing blocks to be downloaded when the client goes
|
|
out of sync.
|
|
|
|
* Resource leaks that may lead to reduction of network activity due
|
|
to a build-up of malfunctioning peer connections.
|
|
|
|
|
|
2020-11-12 v0.6.2
|
|
=================
|
|
|
|
A bugfix release addressing issues discovered in the Toledo network.
|
|
|
|
**New features:**
|
|
|
|
* GossipSub 1.1
|
|
|
|
* The beacon node status bar (footer) now contains a
|
|
time-left-until-synced estimate.
|
|
|
|
* A JSON-RPC method `setLogLevel` for dynamically changing the
|
|
log level of selected components at run-time.
|
|
|
|
* The ability to launch Nimbus with a partially-synced Geth node.
|
|
|
|
**We've fixed:**
|
|
|
|
* A bug preventing the node from proposing blocks when connected
|
|
to a web3 provider
|
|
|
|
* An invalid "corrupted database" error message appearing on start-up
|
|
|
|
* Incorrectly set message-ids in gossip message causing other clients
|
|
to penalise and potentially disconnect our nodes from the network.
|
|
|
|
* An issue occuring when Nimbus is paired with a Geth node
|
|
that is not fully synced.
|
|
|
|
|
|
2020-11-09 Hope (v0.6.0)
|
|
========================
|
|
|
|
`Nimbus eth2` 0.6.0 was the first externally audited and stable release
|
|
of our beacon node software. When compared to the 0.5x series, it features
|
|
significant reductions in storage and memory requirements, a faster sync
|
|
speed, and a plethora of usability and security enhancements across the
|
|
board. Under normal network conditions, the delivery rate of attestations
|
|
and block proposals is expected to be above 99%. Going forward, our release
|
|
schedule will start to accelerate, with multiple new releases expected before
|
|
the Eth2 mainnet launch.
|
|
|
|
**Changelog highlights include:**
|
|
|
|
* Full support for the 1.0 Eth2 phase0 spec and the monitoring of the
|
|
mainnet validator deposit contract.
|
|
|
|
* LibP2P and GossipSub fixes which drastically improve the delivery of
|
|
attestations and blocks (nearly 100% expected rate of delivery).
|
|
|
|
* Fixes for all major resource leaks: you no longer need to restart your
|
|
node to improve its performance.
|
|
|
|
* Efficient caching and storage mechanisms: ensures our memory consumption
|
|
remains comparatively low both during smooth and turbulent network conditions.
|
|
|
|
* Several storage and networking optimisations leading to an order of magnitude
|
|
improvement in beacon chain sync speed.
|
|
|
|
* Audits to our codebase by ConsenSys Diligence, NCC Group and Trail of Bits.
|
|
More than 60 of the security findings have already been addressed.
|
|
The remaining items will be resolved before mainnet launch.
|
|
|
|
* Support for pairing with a locally running Geth instance to allow for
|
|
decentralised monitoring of the validator deposit contract.
|
|
|
|
* An extensive user guide for managing the beacon node.
|
|
|
|
* Slashing protection mechanisms + database.
|
|
|
|
* Support for storing the validator signing keys in a separate process, isolated
|
|
from the network, with a minimal attack surface.
