Nucypher

-------------------

Features
~~~~~~~~

- Added support for a user-provided gas price to the ``nucypher stake`` command, using ``--gas-price GWEI``. (`2425 <https://github.com/nucypher/nucypher/issues/2425>`__)


Bugfixes
~~~~~~~~

- Correct CLI problems when setting the min fee rate. Also, simplifies usage by expressing rates in GWEI. (`2390 <https://github.com/nucypher/nucypher/issues/2390>`__)
- Tone-down learning logging messages even more (see issue 1712). Fixes some CLI and exception messages. (`2395 <https://github.com/nucypher/nucypher/issues/2395>`__)
- Fixes logical bug in ``WorkTracker`` to ensure commitment transactions can only be issued once per period. (`2406 <https://github.com/nucypher/nucypher/issues/2406>`__)
- Removes leftover imports of Twisted Logger, using instead our shim (Closes 2404). Also, changes NuCypher Logger behavior to always escape curly braces. (`2412 <https://github.com/nucypher/nucypher/issues/2412>`__)
- Now ``BlockchainInterface.gas_strategy`` always has a value; previously it was possible to pass ``None`` via the constructor (e.g. if the config file had an explicit ``"null"`` value). (`2421 <https://github.com/nucypher/nucypher/issues/2421>`__)
- Take advantage of the changes in PR2410 by retrying worker commitments on failure (`2422 <https://github.com/nucypher/nucypher/issues/2422>`__)
- Domain "leakage", or nodes saving metadata about nodes from other domains (but never being able to verify them) was still possible because domain-checking only occurred in the high-level APIs (and not, for example, when checking metadata POSTed to the node_metadata_exchange endpoint). This fixes that (fixes 2417).

Additionally, domains are no longer separated into "serving" or "learning". Each Learner instance now has exactly one domain, and it is called domain. (`2423 <https://github.com/nucypher/nucypher/issues/2423>`__)


Misc
~~~~

- Updates contract registry after upgrade of StakingEscrow to v5.5.1, at behest of the DAO (proposal 0). (`2402 <https://github.com/nucypher/nucypher/issues/2402>`__)
- Improved newsfragments README file to clarify release note entry naming convention. (`2415 <https://github.com/nucypher/nucypher/issues/2415>`__)

-------------------

Features
~~~~~~~~

- Add CLI functionality for the removal of unused (inactive) sub-stakes. Depending on the staker's sub-stake configuration, this command can reduce the associated worker's gas costs when making commitments. (`2384 <https://github.com/nucypher/nucypher/issues/2384>`__)


Bugfixes
~~~~~~~~

- Automatically restart Ursula worker task on failure. (`2410 <https://github.com/nucypher/nucypher/issues/2410>`__)


Improved Documentation
~~~~~~~~~~~~~~~~~~~~~~

- Update global fee range documentation, including genesis values. (`2363 <https://github.com/nucypher/nucypher/issues/2363>`__)


Misc
~~~~

- Update Ursula network grant availability script for mainnet usage. (`2383 <https://github.com/nucypher/nucypher/issues/2383>`__)
- GitHub Action to ensure that each pull request into main makes an associated release note entry. (`2396 <https://github.com/nucypher/nucypher/issues/2396>`__)

-------------------

Bugfixes
~~~~~~~~

- Temporary workaround for lack of single attribute for the value of "domain" in sprouts and mature nodes. (`2356 <https://github.com/nucypher/nucypher/issues/2356>`__)
- Show the correct fleet state on Ursula status page. (`2368 <https://github.com/nucypher/nucypher/issues/2368>`__)
- Don't crash when handling failed transaction; reduce network learning messages. (`2375 <https://github.com/nucypher/nucypher/issues/2375>`__)
- Reduce the greediness of prometheus metrics collection. (`2376 <https://github.com/nucypher/nucypher/issues/2376>`__)
- Ensure minimum NU stake is allowed instead of stake creation failing for not enough tokens. (`2377 <https://github.com/nucypher/nucypher/issues/2377>`__)
- Fixes to status page based on reworked design done in PR 2351. (`2378 <https://github.com/nucypher/nucypher/issues/2378>`__)
- Track pending Ursula commitment transactions due to slower gas strategies. (`2389 <https://github.com/nucypher/nucypher/issues/2389>`__)

-------------------

Misc
~~~~

- Set default teacher uri for mainnet. (`2367 <https://github.com/nucypher/nucypher/issues/2382>`__)
