Hello,
We have released Stacks version 2.4.0.1.0, available here: https://github.com/stacks-network/stacks-blockchain/releases/tag/2.4.0.1.0.
This release is compatible with chainstate directories from 2.4.0.0.x.
Important Note:
This release *may* require a small command line argument change when using a configuration file.
In previous versions of the stacks-blockchain, a config file could be added as a command line argument with:
```
- --config=/Config.toml
```
With release 2.4.0.1.0, this is now changed to:
```
- --config /Config.toml
```
** Note the removal of the "=" between the argument and the config file location. **
Changelog:
## [2.4.0.1.0]
### Added
- When the Clarity library is built with feature flag `developer-mode`, comments
from the source code are now attached to the `SymbolicExpression` nodes. This
will be useful for tools that use the Clarity library to analyze and
manipulate Clarity source code, e.g. a formatter.
- New RPC endpoint at /v2/constant_val to fetch a constant from a contract.
- A new subsystem, called StackerDB, has been added, which allows a set of
Stacks nodes to store off-chain data on behalf of a specially-crafter smart
contract. This is an opt-in feature; Stacks nodes explicitly subscribe to
StackerDB replicas in their config files.
- Message definitions and codecs for Stacker DB, a replicated off-chain DB
hosted by subscribed Stacks nodes and controlled by smart contracts
- Added 3 new public and regionally diverse bootstrap nodes: est.stacksnodes.org, cet.stacksnodes.org, sgt.stacksnodes.org
In addition, this introduces a set of improvements to the Stacks miner behavior. In
particular:
* The VRF public key can be re-used across node restarts.
* Settings that affect mining are hot-reloaded from the config file. They take
effect once the file is updated; there is no longer a need to restart the
node.
* The act of changing the miner settings in the config file automatically
triggers a subsequent block-build attempt, allowing the operator to force the
miner to re-try building blocks.
* This adds a new tip-selection algorithm that minimizes block orphans within a
configurable window of time.
* When configured, the node will automatically stop mining if it is not achieving a
targeted win rate over a configurable window of blocks.
* When configured, the node will selectively mine transactions from only certain
addresses, or only of certain types (STX-transfers, contract-publishes,
contract-calls).
* When configured, the node will optionally only RBF block-commits if it can
produce a block with strictly more transactions.
### Changed
- `developer-mode` is no longer enabled in the default feature set. This is the correct default behavior, since the stacks-node should NOT build with developer-mode enabled by default. Tools that need to use developer-mode should enable it explicitly.
### Fixed
- The transaction receipts for smart contract publish transactions now indicate
a result of `(err none)` if the top-level code of the smart contract contained
runtime error and include details about the error in the `vm_error` field of
the receipt. Fixes issues #3154, #3328.
- Added config setting `burnchain.wallet_name` which addresses blank wallets no
longer being created by default in recent bitcoin versions. Fixes issue #3596
- Use the current burnchain tip to lookup UTXOs (Issue #3733)
- The node now gracefully shuts down even if it is in the middle of a handshake with
bitcoind. Fixes issue #3734.
