+title: Remove deprecated calls from treasury pallet
+
+doc:
+  - audience: Runtime User
+    description: |
+      This PR remove deprecated calls, relevant tests from `pallet-treasury`.
+      - Remove deprecated calls `propose_spend`, `reject_proposal`, `approve_proposal`.
+      - Replace the code flow of `propose_spend` then `approve_proposal` with `spend_local`
+      - Remove deprecated calls' related weight functions and test cases.
+      - Remove deprecated parameter types: ProposalBond, ProposalBondMaximum, ProposalBondMinimum
+      - Remove pallet treasury's relevant deprecated code in pallet-tips, pallet-bounties and pallet-child-bounties

 ### Dispatchable Functions
 
 General spending/proposal protocol:
-- `propose_spend` - Make a spending proposal and stake the required deposit.
-- `reject_proposal` - Reject a proposal, slashing the deposit.
-- `approve_proposal` - Accept the proposal, returning the deposit.
+- `spend_local` - Propose and approve a spend of treasury funds, enables the
+  creation of spends using the native currency of the chain, utilizing the funds
+  stored in the pot
+- `spend` - Propose and approve a spend of treasury funds, allows spending any
+  asset kind managed by the treasury
+- `remove_approval` - Force a previously approved proposal to be removed from
+  the approval queue
+- `payout` - Claim a spend
+- `check_status` - Check the status of the spend and remove it from the storage
+  if processed
+- `void_spend` - Void previously approved spend
