Crunch v0.5.0

Note: This release was built using rustc 1.58.1 (db9d1b20b 2022-01-20)

✨ New

• Collapsible section to show/hide details with a brief summary highlighting crunch actions. Closes #3
• Optional flag 'stashes-url'. This flag allows stashes to be loaded into crunch from a remote endpoint. Payouts are triggered for these stashes without the need of a service restart or a local file configuration change. Closes #6
• Added a random waiting period (up to a maximum of 120 seconds) before triggering the procedure to execute the batch calls. This aims to prevent a block race from all crunch bots at the beginning of each era.

🔧 Changes

• Fixes #4 Already claimed rewards issue
• Fixes default endpoints by setting the default :443 port number

Crunch v0.4.0

Note: This release was built using rustc 1.57.0 (f1edd0429 2021-11-29)

✨ New

• New maximum-calls flag with default value of 8. By default crunch collects all the outstanding payouts from previous eras and group all the extrinsic payout calls in group of 8 (or whatever value defined by this flag) so that a single batch call per group can be made.
  Note 1: Using batch calls rather than single payouts we could expect a significant drop in transaction fees and a significant increase on crunch performance.
  Note 2: The collection of all outstanding payouts from previous eras is limited by two other flags. The first being maximum-payouts which default value is 4 - this flag limits the number of payouts per stash. The other one is the maximum-history-eras flag, which default value is also 4 - this flag limits the number of past eras crunch will look for unclaimed rewards - but this flag is only executed if short flag is also used in the configuration. This is done so that crunch can run efficiently every era.

🔧 Changes

• Changed single payouts for batch calls.
• Update subxt dependency to revision 41bd8cc

📦️ Builtin runtimes metadata

• Polkadot/9140

Crunch v0.3.2

Note: This release was built using rustc 1.56.1 (59eed8a2a 2021-11-01)

Crunch v0.3.0

Note: This release was built using rustc 1.55.0 (c8dfcfe04 2021-09-06)

💥 Breaking changes

• Fix subxt dependency for metadata V14 and support Polkadot/Kusama 9110 runtime

🔧 Changes

• Currently batch calls are no longer supported on this version only single payouts -> fix will be available soon

Crunch v0.2.2

Note: This release was built using rustc 1.55.0 (c8dfcfe04 2021-09-06)

✨ New

• Add optional --maximum_history_eras flag with default value of 4.
  Note 1: This flag is only valid if --short flag is also present. By default crunch will only check for unclaimed rewards in the last 4 eras rather than the value specified in constant history_depth (usually 84) as in previous versions. This will just speed up crunch by avoiding repeated checks every era.
  Note 2: If running crunch in verbose mode the check in the last 84 eras is enforced by default since Inclusion and Crunched stats are relevant only with all eras history available on-chain.

🐛 Bugfix

• Fix loading configuration variables like CRUNCH_SEED_PATH, CRUNCH_MAXIMUM_PAYOUTS specified in .env configuration file.
• Fix issue when new chains have potentially a current_era value lower than the history_depth constant.

Crunch v0.1.19

Note: This release was built using rustc 1.55.0 (c8dfcfe04 2021-09-06)
