Pavel Orlov2023-06-30parent: #1ecd8fc.patch.diff
in: master
* feat!: decoupling configuration&collators pallets

BREAKING CHANGE: pallet `collator-selection` no longer has a tight coupling with the `configuration` pallet

* refactor(collator-selection): type bounds, tests

* refactor(collator-selection): tests

* add ci step for banchmark tests

* add opsFee tests

+## [5.0.0] - 2023-06-27
+
+### Major change
+
+- The dependency (tight coupling) this pallet on the configuration pallet has been removed.
+
 ## [4.0.0] - 2022-12-29
 
 ### Added
 
 - Entire functionality moved over from cumulus/pallet-collator-selection (v3.0.0). Refactored business logic:
-   - Added an extra step for candidacy, `get_license`, at which payment happens. The number of license holders is unlimited. 
-      - Only licensed accounts can apply for candidacy with `onboard`. No extra deposits are made.
-      - Active candidates may `offboard`, but they will retain their license.
-      - Deposit is returned, and candidacy possibly removed with `release_license`.
-      - License can be forcibly forfeited and candidacy removed with `force_release_license`.
-   - Failing collators' deposits will now be fully slashed, and funds will be redirected to Treasury.
-   - Unify `MaxInvulnerables` and `MaxCandidates` into `MaxCollators`.
-   - Remove `MinCandidates`.
-   - Minimal amount of invulnerables is now 1.
-   - Both invulnerables and candidates count against the limits together, however invulnerables ignore `DesiredCollators`.
-   - `KickThreshold` is made configurable.
-   - `DesiredCollators`, `LicenseBond`, and `KickThreshold` are moved to and referenced from `pallet-configuration`.
-   - Naming changes to better reflect the new functionality.
-   - More minor changes, tests, benchmarks, etc.
