Alcyone 2.4 Release Notes

Mesh 1460/STO improvements #848

new features

• STOs can now have a name and a minimum investment amount.

modified API

• Fundraiser data struct changed to contain the STO status and min investment amount, Schema update required.
• FundraiserCreated event changed to contain the STO name.

Refactored Multisig benchmarks #840

modified API

• change_all_signers_and_sigs_required has been removed. The users should use utility.batch function.

Re enable slashing #849

modified logic

• Slashing will happen even when slashing targets are set to None. However, the amount of slash will be zero in those cases.

MESH-1431/Allow fix rewards #841

modified logic

• Introduce a fixed reward process, which will kick in whenever the total_issuance() >= MaxInflatedTotalIssuance::get().

MESH-1418/Enforce cdd_id uniqueness #839

modified logic

• Either a single (unique within its claims) cdd_id is allowed for a given identity or it can be default_cdd_id() only if the claims issuer is the systematic issuers. Ex - Alice can have default_cdd_id() that is provided by the systematic issuers and Alice can also possess one non-default cdd_id claim which should be the same for all its non-default cdd claims.

Misc cleanups & refactorings, Part 2 #837

modified logic

• Check permissions in Pips::{reschedule_execution, snapshot, clear_snapshot}.

Fix PIA semantics and forwarded_call permissions #834

modified logic

• Only the PIA (which defaults to the ticker owner) can call issue, redeem and controller_transfer. Tokens are moved to the PIAs default portfolio.
• When using identity::forwarded_call permissions are now checked correctly for the calling DID, rather than the original origin. identity::forwarded_call is only used when an identity is a key to another identity.
• Recursive calls to identity::forwarded_call are not allowed.

Remove duplicated schedule event and fix comments #833

modified API

• Changes the ExecutionScheduled event to only contain the new scheduled block, not the previous one

Misc cleanups & refactorings, Part 1 #831

modified logic

• Fixed investor count

MESH-1433: Introduce limits for fixed values in CA extrinsic weights #827

modified logic

• set_default_targets(..., targets) requires that the number of DIDs in targets <= a new limit, or an error occurs. The error occurs also in ìnitiate_corporate_action if targets is provided under the same condition.
• set_did_withholding_tax(..., did, Some(tax)) requires that the number of DIDs for which a withholding-tax override is set is strictly below (<) a new limit or an error occurs. The error occurs also in ìnitiate_corporate_action if withholding_tax.len() is strictly above the limit.

Remove STO, Voting, & Dividend #826

Mesh 1373/ Configurable limit on no. of validators for an entity #821

new features

• Associated permissioned identity with the intended count of validators they are able to run.

• Introduced the PermissionedIdentityPrefs type in the schema to facilitate the above functionality.
• New extrinsic update_permissioned_validator_intended_count is added to update the intended_count for a given permissioned identity.

modified API

• Introduced intended_count param for add_permissioned_validator dispatch.
• Removed Commission type from the schema and from the runtime as well.

modified logic

• Only permissioned entities are allowed to show the intended to run a validator.

• Schema: DocumentHash has been updated.

Add getter to retrieve all the exempted identities #816

new features

• Introduced get_all_exempted_identities() getter function in PTM contract.

MESH-1416: Require IU claims for payer and receiver of transfers #812
