No significant changes.

v4.5.0 (2021-01-14)

Features

  • Compare Ursula IP address with configuration values on startup to help ensure node availability. (#2462)

  • Arrangement proposals and policy enactment are performed in parallel, with more nodes being considered as some of the requests fail. This improves granting reliability. (#2482)

Bugfixes

  • More logging added for arrangement proposal failures, and more suitable exceptions thrown. (#2479)

  • Ignore pending Ethereum transactions for purposes of gas estimation. (#2486)

  • Fix rtd build after #2477 (#2489)

  • (#2491, #2498)

  • Fix rtd build after #2477 and #2489 (#2492)

  • cloudworkers bugfixes, cli args refactor and new “cloudworkers stop” feature. (#2494)

  • Gentler handling of unsigned stamps from stranger Ursulas on status endpoint (#2515)

  • Restore the re-raising behavior in BlockchainInterface._handle_failed_transaction() (#2521)

Improved Documentation

  • Auto docs generation for smart contracts (#2477)

  • Add pricing protocol & economics paper to main repo readme and docs homepage. (#2520)

Deprecations and Removals

  • (#2470)

  • Deprecated manual worker commitments using the CLI. (#2507)

Misc

  • Relock dependencies and update relock script. (#2440)

  • Fixed failing readthedocs build due to dependency mismatches in docs requirements. (#2496)

  • (#2499)

v4.4.0 (2020-12-24)

Features

  • Introduces “Character Cards” a serializable identity abstraction and ‘nucypher contacts’ CLI to support. (#2115)

    • nucypher cloudworkers now contains a complete and comprehensive set of features for easily managing, backing up and restoring one to many workers (#2365)

  • New composite gas strategy that uses the median from three different gas price oracles (currently, Etherchain, Upvest and gas-oracle.zoltu.io), which behaves more robustly against sporadic errors in the oracles (e.g., spikes, stuck feeds). (#2420)

  • Improve gas strategy selection: Infura users now can choose between slow, medium and fast, and a maximum gas price can be configured with –max-gas-price. (#2445)

Bugfixes

  • Slowly try more and more nodes if some of the initial draft for a policy were inaccessible. (#2416)

  • Fix bad cli handling in several cloudworkers commands, improved envvar handling. (#2475)

Misc

  • (#2244, #2483)

  • Solidity compilation refinements (#2461)

  • Deprecates internally managed geth process management (#2466)

  • Include checksum and IP addresses in exception messages for Rejected. (#2467)

  • Deprecates managed ethereum client syncing and stale interface methods (#2468)

  • Improves console messages for stakeholder CLI initialization and worker startup. (#2474)

  • Introduce a template to describe Pull Requests. (#2476)

v4.3.0 (2020-12-08)

Features

  • Introduces shorthand options for –bob-verifying-key (-bvk), –bob-encrypting-key (-bek) and alice verifying key (-avk) for CLI commands. (#2459)

  • Complete interactive collection of policy parameters via alice grant CLI. (#2460)

Bugfixes

  • Corrected minimum stake value for –min-stake CLI option (#2371)

Misc

  • Introduces a probationary period for policy creation in the network, until 2021-02-28 23:59:59 UTC. (#2431)

  • Supplies AccessDenied exception class for better incorrect password handling. (#2451)

  • Maintain compatibility with python 3.6 (removes re.Pattern annotations) (#2458)

v4.2.1 (2020-12-04)

Bugfixes

  • Removes tests import from constants module causing pip installed versions to crash. (#2452)

v4.2.0 (2020-12-03)

Features

  • Improve user experience when removing unused substakes (CLI and docs). (#2450)

Bugfixes

  • Fix bug in deployer logic while transferring ownership of StakingInterfaceRouter (#2369)

  • Allow arbitrary decimal precision when entering NU amounts to nucypher CLI. (#2441)

Improved Documentation

  • Document usage of hardware wallets for signing. (#2346)

  • Improvements to the staking guide: extending description of winddown command, other minor corrections. (#2434)

Misc

  • Rework internal solidity compiler usage to implement “Standard JSON Compile”. (#2439)

  • Introduces –config-path and –logging-path CLI flags displaying default nucypher directories (#2446)

v4.1.2 (2020-11-09)

Features

  • Added support for a user-provided gas price to the nucypher stake command, using --gas-price GWEI. (#2425)

Bugfixes

  • Correct CLI problems when setting the min fee rate. Also, simplifies usage by expressing rates in GWEI. (#2390)

  • Tone-down learning logging messages even more (see issue #1712). Fixes some CLI and exception messages. (#2395)

  • Fixes logical bug in WorkTracker to ensure commitment transactions can only be issued once per period. (#2406)

  • Removes leftover imports of Twisted Logger, using instead our shim (Closes #2404). Also, changes NuCypher Logger behavior to always escape curly braces. (#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)

  • Take advantage of the changes in PR#2410 by retrying worker commitments on failure (#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)

Misc

  • Updates contract registry after upgrade of StakingEscrow to v5.5.1, at behest of the DAO (proposal #0). (#2402)

  • Improved newsfragments README file to clarify release note entry naming convention. (#2415)

v4.1.1 (2020-10-29)

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)

Bugfixes

  • Automatically restart Ursula worker task on failure. (#2410)

Improved Documentation

  • Update global fee range documentation, including genesis values. (#2363)

Misc

  • Update Ursula network grant availability script for mainnet usage. (#2383)

  • GitHub Action to ensure that each pull request into main makes an associated release note entry. (#2396)

v4.1.0 (2020-10-19)

Bugfixes

  • Temporary workaround for lack of single attribute for the value of “domain” in sprouts and mature nodes. (#2356)

  • Show the correct fleet state on Ursula status page. (#2368)

  • Don’t crash when handling failed transaction; reduce network learning messages. (#2375)

  • Reduce the greediness of prometheus metrics collection. (#2376)

  • Ensure minimum NU stake is allowed instead of stake creation failing for not enough tokens. (#2377)

  • Fixes to status page based on reworked design done in PR #2351. (#2378)

  • Track pending Ursula commitment transactions due to slower gas strategies. (#2389)

v4.0.1 (2020-10-14)

Misc

  • Set default teacher uri for mainnet. (#2367)

v4.0.0 (2020-10-14)
