      Allow privileged virtual bond in Staking pallet (#3889) · e504c41a
      Ankan authored 
      This is the first PR in preparation for
https://github.com/paritytech/polkadot-sdk/issues/454.

## Follow ups:
- https://github.com/paritytech/polkadot-sdk/pull/3904.
- https://github.com/paritytech/polkadot-sdk/pull/3905.

Overall changes are documented here (lot more visual 😍):
https://hackmd.io/@ak0n/454-np-governance

[Maybe followup](https://github.com/paritytech/polkadot-sdk/issues/4217)
with migration of storage item `VirtualStakers` as a bool or enum in
`Ledger`.

## Context
We want to achieve a way for a user (`Delegator`) to delegate their
funds to another account (`Agent`). Delegate implies the funds are
locked in delegator account itself. Agent can act on behalf of delegator
to stake directly on Staking pallet.

The delegation feature is added to Staking via another pallet
`delegated-staking` worked on
[here](https://github.com/paritytech/polkadot-sdk/pull/3904).

## Introduces:
### StakingUnchecked Trait
As the name implies, this trait allows unchecked (non-locked) mutation
of staking ledger. These apis are only meant to be used by other pallets
in the runtime and should not be exposed directly to user code path.
Also related: https://github.com/paritytech/polkadot-sdk/issues/3888.

### Virtual Bond
Allows other pallets to stake via staking pallet while managing the
locks on these accounts themselves. Introduces another storage
`VirtualStakers` that whitelist these accounts.

We also restrict virtual stakers to set reward account as themselves.
Since the account has no locks, we cannot support compounding of
rewards. Conservatively, we require them to set a separate account
different from the staker. Since these are code managed, it should be
easy for another pallet to redistribute reward and rebond them.

### Slashes
Since there is no actual lock maintained by staking-pallet for virtual
stakers, this pallet does not apply any slashes. It is then important
for pallets managing virtual stakers to listen to slashing events and
apply necessary slashes.

      Asset Conversion: Pool Touch Call (#3251) · 305d311d
      Muharem Ismailov authored 
      Introduce `touch` call designed to address operational prerequisites
before providing liquidity to a pool.

This function ensures that essential requirements, such as the presence
of the pool's accounts, are fulfilled. It is particularly beneficial in
scenarios where a pool creator removes the pool's accounts without
providing liquidity.

      - Moved `substrate/frame/contracts/src/tests/builder.rs` into a pub
test_utils module, so we can use that in the
`pallet-contracts-mock-network` tests
- Refactor xcm tests to use XCM builders, and simplify the use case for

      Fix nostd build of several crates (#4060) · 7a2c9d4a
      Oliver Tale-Yazdi authored 
      

Preparation for https://github.com/paritytech/polkadot-sdk/pull/3935

Changes:
- Add some `default-features = false` for the case that a crate and that
dependency both support nostd builds.
- Shuffle files around of some benchmarking-only crates. These
conditionally disabled the `cfg_attr` for nostd and pulled in libstd.
Example [here](https://github.com/ggwpez/zepter/pull/95). The actual
logic is moved into a `inner.rs` to preserve nostd capability of the
crate in case the benchmarking feature is disabled.
- Add some `use sp_std::vec` where needed.
- Remove some `optional = true` in cases where it was not optional.
- Removed one superfluous `cfg_attr(not(feature = "std"), no_std..`.

All in all this should be logical no-op.

      chainHead: Report unique hashes for pruned blocks (#3667) · bfbf7f5d
      Alexandru Vasile authored 
      

This PR ensures that the reported pruned blocks are unique.

While at it, ensure that the best block event is properly generated when
the last best block is a fork that will be pruned in the future.

To achieve this, the chainHead keeps a LRU set of reported pruned blocks
to ensure the following are not reported twice:

```bash
	 finalized -> block 1 -> block 2 -> block 3
	
	                      -> block 2 -> block 4 -> block 5
	
	           -> block 1 -> block 2_f -> block 6 -> block 7 -> block 8
```

When block 7 is finalized the branch [block 2; block 3] is reported as
pruned.
When block 8 is finalized the branch [block 2; block 4; block 5] should
be reported as pruned, however block 2 was already reported as pruned at
the previous step.

This is a side-effect of the pruned blocks being reported at level N -
1. For example, if all pruned forks would be reported with the first
encounter (when block 6 is finalized we know that block 3 and block 5
are stale), we would not need the LRU cache.

      Improve doc for pallet macro and config macro (#4146) · ca7c01c8
      thiolliere authored 
      Improve doc:

* the pallet macro is actually referring to 2 places, for the module and
for the struct placeholder but doesn't really clarify it (I should have
named the latter just `pallet_struct` or something but it is a bit late)

* The doc of `with_default` is a bit confusing too IMO.

      Muharem Ismailov authored 
      Introduce `PalletId` as an additional seed parameter for pool's account
id derivation.

The PR also introduces the `pallet_asset_conversion_ops` pallet with a
call to migrate a given pool to thew new account. Additionally
`fungibles::lifetime::ResetTeam` and `fungible::lifetime::Refund`
traits, to facilitate the migration of pools.

      XCM coretime region transfers (#3455) · e6f3106d
      Sergej Sakac authored 
      

This PR introduces changes enabling the transfer of coretime regions via
XCM.

TL;DR: There are two primary issues that are resolved in this PR:

1. The `mint` and `burn` functions were not implemented for coretime
regions. These operations are essential for moving assets to and from
the XCM holding register.
2. The transfer of non-fungible assets through XCM was previously
disallowed. This was due to incorrectly benchmarking non-fungible asset
transfers via XCM, which led to assigning it a weight of `Weight::Max`,
effectively preventing its execution.

### `mint_into` and `burn` implementation

This PR addresses the issue with cross-chain transferring regions back
to the Coretime chain. Remote reserve transfers are performed by
withdrawing and depositing the asset to and from the holding registry.
This requires the asset to support burning and minting functionality.

This PR adds burning and minting; however, they work a bit differently
than usual so that the associated region record is not lost when
burning. Instead of removing all the data, burning will set the owner of
the region to `None`, and when minting it back, it will set it to an
actual value. So, when cross-chain transferring, withdrawing into the
registry will remove the region from its original owner, and when
depositing it from the registry, it will set its owner to another
account

This was originally implemented in this PR: #3455, however we decided to
move all of it to this single PR
(https://github.com/paritytech/polkadot-sdk/pull/3455#discussion_r1547324892)

### Fixes made in this PR

- Update the `XcmReserveTransferFilter` on coretime chain since it is
meant as a reserve chain for coretime regions.
- Update the XCM benchmark to use `AssetTransactor` instead of assuming
`pallet-balances` for fungible transfers.
- Update the XCM benchmark to properly measure weight consumption for
nonfungible reserve asset transfers. ATM reserve transfers via the
extrinsic do not work since the weight for it is set to `Weight::max()`.

Closes: https://github.com/paritytech/polkadot-sdk/issues/865
