If an XCM execution fails or ends with leftover assets, these will be trapped. In order to claim them, a custom XCM has to be executed, with the `ClaimAsset` instruction. However, arbitrary XCM execution is not allowed everywhere yet and XCM itself is still not easy enough to use for users out there with trapped assets. This new extrinsic in `pallet-xcm` will allow these users to easily claim their assets, without concerning themselves with writing arbitrary XCMs. Part of fixing https://github.com/paritytech/polkadot-sdk/issues/3495 --------- Co-authored-by: command-bot <> Co-authored-by:

This MR is the merge of https://github.com/paritytech/substrate/pull/14414 and https://github.com/paritytech/substrate/pull/14275. It implements [RFC#13](https://github.com/polkadot-fellows/RFCs/pull/13), closes https://github.com/paritytech/polkadot-sdk/issues/198. ----- This Merge request introduces three major topicals: 1. Multi-Block-Migrations 1. New pallet `poll` hook for periodic service work 1. Replacement hooks for `on_initialize` and `on_finalize` in cases where `poll` cannot be used and some more general changes to FRAME. The changes for each topical span over multiple crates. They are listed in topical order below. # 1.) Multi-Block-Migrations Multi-Block-Migrations are facilitated by creating `pallet_migrations` and configuring `System::Config::MultiBlockMigrator` to point to it. Executive picks this up and triggers one step of the migrations pallet per block. The chain is in lockdown mode for as long as an MBM is ongoing. Executive does this by polling `MultiBlockMigrator::ongoing` and not allowing any transaction in a block, if true. A MBM is defined through trait `SteppedMigration`. A condensed version looks like this: ```rust /// A migration that can proceed in multiple steps. pub trait SteppedMigration { type Cursor: FullCodec + MaxEncodedLen; type Identifier: FullCodec + MaxEncodedLen; fn id() -> Self::Identifier; fn max_steps() -> Option<u32>; fn step( cursor: Option<Self::Cursor>, meter: &mut WeightMeter, ) -> Result<Option<Self::Cursor>, SteppedMigrationError>; } ``` `pallet_migrations` can be configured with an aggregated tuple of these migrations. It then starts to migrate them one-by-one on the next runtime upgrade. Two things are important here: - 1. Doing another runtime upgrade while MBMs are ongoing is not a good idea and can lead to messed up state. - 2. **Pallet Migrations MUST BE CONFIGURED IN `System::Config`, otherwise it is not used.** The pallet supports an `UpgradeStatusHandler` that can be used to notify external logic of upgrade start/finish (for example to pause XCM dispatch). Error recovery is very limited in the case that a migration errors or times out (exceeds its `max_steps`). Currently the runtime dev can decide in `FailedMigrationHandler::failed` how to handle this. One follow-up would be to pair this with the `SafeMode` pallet and enact safe mode when an upgrade fails, to allow governance to rescue the chain. This is currently not possible, since governance is not `Mandatory`. ## Runtime API - `Core`: `initialize_block` now returns `ExtrinsicInclusionMode` to inform the Block Author whether they can push transactions. ### Integration Add it to your runtime implementation of `Core` and `BlockBuilder`: ```patch diff --git a/runtime/src/lib.rs b/runtime/src/lib.rs @@ impl_runtime_apis! { impl sp_block_builder::Core<Block> for Runtime { - fn initialize_block(header: &<Block as BlockT>::Header) { + fn initialize_block(header: &<Block as BlockT>::Header) -> RuntimeExecutiveMode { Executive::initialize_block(header) } ... } ``` # 2.) `poll` hook A new pallet hook is introduced: `poll`. `Poll` is intended to replace mostly all usage of `on_initialize`. The reason for this is that any code that can be called from `on_initialize` cannot be migrated through an MBM. Currently there is no way to statically check this; the implication is to use `on_initialize` as rarely as possible. Failing to do so can result in broken storage invariants. The implementation of the poll hook depends on the `Runtime API` changes that are explained above. # 3.) Hard-Deadline callbacks Three new callbacks are introduced and configured on `System::Config`: `PreInherents`, `PostInherents` and `PostTransactions`. These hooks are meant as replacement for `on_initialize` and `on_finalize` in cases where the code that runs cannot be moved to `poll`. The reason for this is to make the usage of HD-code (hard deadline) more explicit - again to prevent broken invariants by MBMs. # 4.) FRAME (general changes) ## `frame_system` pallet A new memorize storage item `InherentsApplied` is added. It is used by executive to track whether inherents have already been applied. Executive and can then execute the MBMs directly between inherents and transactions. The `Config` gets five new items: - `SingleBlockMigrations` this is the new way of configuring migrations that run in a single block. Previously they were defined as last generic argument of `Executive`. This shift is brings all central configuration about migrations closer into view of the developer (migrations that are configured in `Executive` will still work for now but is deprecated). - `MultiBlockMigrator` this can be configured to an engine that drives MBMs. One example would be the `pallet_migrations`. Note that this is only the engine; the exact MBMs are injected into the engine. - `PreInherents` a callback that executes after `on_initialize` but before inherents. - `PostInherents` a callback that executes after all inherents ran (including MBMs and `poll`). - `PostTransactions` in symmetry to `PreInherents`, this one is called before `on_finalize` but after all transactions. A sane default is to set all of these to `()`. Example diff suitable for any chain: ```patch @@ impl frame_system::Config for Test { type MaxConsumers = ConstU32<16>; + type SingleBlockMigrations = (); + type MultiBlockMigrator = (); + type PreInherents = (); + type PostInherents = (); + type PostTransactions = (); } ``` An overview of how the block execution now looks like is here. The same graph is also in the rust doc. <details><summary>Block Execution Flow</summary> <p> ![Screenshot 2023-12-04 at 19 11 29](https://github.com/paritytech/polkadot-sdk/assets/10380170/e88a80c4-ef11-4faa-8df5-8b33a724c054) </p> </details> ## Inherent Order Moved to https://github.com/paritytech/polkadot-sdk/pull/2154 --------------- ## TODO - [ ] Check that `try-runtime` still works - [ ] Ensure backwards compatibility with old Runtime APIs - [x] Consume weight correctly - [x] Cleanup --------- Signed-off-by:

## Problem During the bumping of the `polkadot-fellows` repository to `[email protected]`, I encountered a situation where the benchmarks `teleport_assets` and `reserve_transfer_assets` in AssetHubKusama started to fail. This issue arose due to a decreased ED balance for AssetHubs introduced [here](https://github.com/polkadot-fellows/runtimes/pull/158/files#diff-80668ff8e793b64f36a9a3ec512df5cbca4ad448c157a5d81abda1b15f35f1daR213), and also because of a [missing CI pipeline](https://github.com/polkadot-fellows/runtimes/issues/197) to check the benchmarks, which went unnoticed. These benchmarks expect the `caller` to have enough: 1. balance to transfer (BTT) 2. balance for paying delivery (BFPD). So the initial balance was calculated as `ED * 100`, which seems reasonable: ``` const ED_MULTIPLIER: u32 = 100; let balance = existential_deposit.saturating_mul(ED_MULTIPLIER.into());` ``` The problem arises when the price for delivery is 100 times higher than the existential deposit. In other words, when `ED * 100` does not cover `BTT` + `BFPD`. I check AHR/AHW/AHK/AHP and this problem has only AssetHubKusama ``` ED: 3333333 calculated price to parent delivery: 1031666634 (from xcm logs from the benchmark) --- 3333333 * 100 - BTT(3333333) - BFPD(1031666634) = −701666667 ``` which results in the error; ``` 2024-02-23 09:19:42 Unable to charge fee with error Module(ModuleError { index: 31, error: [17, 0, 0, 0], message: Some("FeesNotMet") }) Error: Input("Benchmark pallet_xcm::reserve_transfer_assets failed: FeesNotMet") ``` ## Solution The benchmarks `teleport_assets` and `reserve_transfer_assets` were fixed by removing `ED * 100` and replacing it with `DeliveryHelper` logic, which calculates the (almost real) price for delivery and sets it along with the existential deposit as the initial balance for the account used in the benchmark. ## TODO - [ ] patch for 1.6 - https://github.com/paritytech/polkadot-sdk/pull/3466 - [ ] patch for 1.7 - https://github.com/paritytech/polkadot-sdk/pull/3465 - [ ] patch for 1.8 - TODO: PR --------- Co-authored-by:

[frame] `#[pallet::composite_enum]` improved variant count handling + removed `pallet_balances`'s `MaxHolds` config (#2657) I started this investigation/issue based on @liamaharon question [here](https://github.com/paritytech/polkadot-sdk/pull/1801#discussion_r1410452499). ## Problem The `pallet_balances` integrity test should correctly detect that the runtime has correct distinct `HoldReasons` variant count. I assume the same situation exists for RuntimeFreezeReason. It is not a critical problem, if we set `MaxHolds` with a sufficiently large value, everything should be ok. However, in this case, the integrity_test check becomes less useful. **Situation for "any" runtime:** - `HoldReason` enums from different pallets: ```rust /// from pallet_nis #[pallet::composite_enum] pub enum HoldReason { NftReceipt, } /// from pallet_preimage #[pallet::composite_enum] pub enum HoldReason { Preimage, } // from pallet_state-trie-migration #[pallet::composite_enum] pub enum HoldReason { SlashForContinueMigrate, SlashForMigrateCustomTop, SlashForMigrateCustomChild, } ``` - generated `RuntimeHoldReason` enum looks like: ```rust pub enum RuntimeHoldReason { #[codec(index = 32u8)] Preimage(pallet_preimage::HoldReason), #[codec(index = 38u8)] Nis(pallet_nis::HoldReason), #[codec(index = 42u8)] StateTrieMigration(pallet_state_trie_migration::HoldReason), } ``` - composite enum `RuntimeHoldReason` variant count is detected as `3` - we set `type MaxHolds = ConstU32<3>` - `pallet_balances::integrity_test` is ok with `3`(at least 3) However, the real problem can occur in a live runtime where some functionality might stop working. This is due to a total of 5 distinct hold reasons (for pallets with multi-instance support, it is even more), and not all of them can be used because of an incorrect `MaxHolds`, which is deemed acceptable according to the `integrity_test`: ``` // pseudo-code - if we try to call all of these: T::Currency::hold(&pallet_nis::HoldReason::NftReceipt.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_preimage::HoldReason::Preimage.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForContinueMigrate.into(), &nft_owner, deposit)?; // With `type MaxHolds = ConstU32<3>` these two will fail T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomTop.into(), &nft_owner, deposit)?; T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomChild.into(), &nft_owner, deposit)?; ``` ## Solutions A macro `#[pallet::*]` expansion is extended of `VariantCount` implementation for the `#[pallet::composite_enum]` enum type. This expansion generates the `VariantCount` implementation for pallets' `HoldReason`, `FreezeReason`, `LockId`, and `SlashReason`. Enum variants must be plain enum values without fields to ensure a deterministic count. The composite runtime enum, `RuntimeHoldReason` and `RuntimeFreezeReason`, now sets `VariantCount::VARIANT_COUNT` as the sum of pallets' enum `VariantCount::VARIANT_COUNT`: ```rust #[frame_support::pallet(dev_mode)] mod module_single_instance { #[pallet::composite_enum] pub enum HoldReason { ModuleSingleInstanceReason1, ModuleSingleInstanceReason2, } ... } #[frame_support::pallet(dev_mode)] mod module_multi_instance { #[pallet::composite_enum] pub enum HoldReason<I: 'static = ()> { ModuleMultiInstanceReason1, ModuleMultiInstanceReason2, ModuleMultiInstanceReason3, } ... } impl self::sp_api_hidden_includes_construct_runtime::hidden_include::traits::VariantCount for RuntimeHoldReason { const VARIANT_COUNT: u32 = 0 + module_single_instance::HoldReason::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance1>::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance2>::VARIANT_COUNT + module_multi_instance::HoldReason::<module_multi_instance::Instance3>::VARIANT_COUNT; } ``` In addition, `MaxHolds` is removed (as suggested [here](https://github.com/paritytech/polkadot-sdk/pull/2657#discussion_r1443324573)) from `pallet_balances`, and its `Holds` are now bounded to `RuntimeHoldReason::VARIANT_COUNT`. Therefore, there is no need to let the runtime specify `MaxHolds`. ## For reviewers Relevant changes can be found here: - `substrate/frame/support/procedural/src/lib.rs` - `substrate/frame/support/procedural/src/pallet/parse/composite.rs` - `substrate/frame/support/procedural/src/pallet/expand/composite.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/composite_helper.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/hold_reason.rs` - `substrate/frame/support/procedural/src/construct_runtime/expand/freeze_reason.rs` - `substrate/frame/support/src/traits/misc.rs` And the rest of the files is just about removed `MaxHolds` from `pallet_balances` ## Next steps Do the same for `MaxFreezes` https://github.com/paritytech/polkadot-sdk/issues/2997 . --------- Co-authored-by: command-bot <> Co-authored-by:

Reverts paritytech/polkadot-sdk#2302.
🤦 ♂️ should have checked the migration CI first. We either need to reduce the `max_message_size` for the open HRMP channels on the failing chains or increase the `PageSize` of the XCMP queue. Both would be fine on a test-net, but i assume this will also fail before the next SP runtime upgrade so first need to think what best to do. AFAIK its not possible currently to change the `max_message_size` of an open HRMP channel.

Remove `without_storage_info` from the XCMP queue pallet. Part of https://github.com/paritytech/polkadot-sdk/issues/323 Changes: - Limit the number of channels that can be suspended at the same time. - Limit the number of channels that can have messages or signals pending at the same time. A No-OP migration is put in place to ensure that all `BoundedVec`s still decode and not truncate after upgrade. The storage version is thereby bumped to 4 to have our tooling remind us to deploy that migration. --------- Signed-off-by:

Moved from: https://github.com/paritytech/polkadot/pull/6951 closes https://github.com/paritytech/polkadot-sdk/issues/490 - [x] update cumulus --- This PR introduces transactional processing of certain xcm instructions. For the list of instructions checkout https://github.com/paritytech/polkadot-sdk/issues/490. The transactional processing is implemented as an xcm-executor config item. The two implementations in this PR are `FrameTransactionalProcessor` and `()`. The `()` implementation does no transactional processing. Each implementation of the `ProcessTransaction` trait has an `IS_TRANSACTIONAL` const that tells the XCVM if transactional processing is actually implemented. If Transactional processing is implemented, changes to touched registers should also be rolled back to prevent inconsistencies. Note for reviewers: Check out the following safety assumption: https://github.com/paritytech/polkadot-sdk/pull/1222/files#diff-4effad7d8c1c9de19fd27e18661cbf2128c8718f3b2420a27d2f816e0749ea53R30 --------- Co-authored-by:

# Note for reviewer Most changes are just syntax changes necessary for the new version. Most important files should be the ones under the `xcm` folder. # Description Added XCMv4. ## Removed `Multi` prefix The following types have been renamed: - MultiLocation -> Location - MultiAsset -> Asset - MultiAssets -> Assets - InteriorMultiLocation -> InteriorLocation - MultiAssetFilter -> AssetFilter - VersionedMultiAsset -> VersionedAsset - WildMultiAsset -> WildAsset - VersionedMultiLocation -> VersionedLocation In order to fix a name conflict, the `Assets` in `xcm-executor` were renamed to `HoldingAssets`, as they represent assets in holding. ## Removed `Abstract` asset id It was not being used anywhere and this simplifies the code. Now assets are just constructed as follows: ```rust let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into(); ``` No need for specifying `Concrete` anymore. ## Outcome is now a named fields struct Instead of ```rust pub enum Outcome { Complete(Weight), Incomplete(Weight, Error), Error(Error), } ``` we now have ```rust pub enum Outcome { Complete { used: Weight }, Incomplete { used: Weight, error: Error }, Error { error: Error }, } ``` ## Added Reanchorable trait Now both locations and assets implement this trait, making it easier to reanchor both. ## New syntax for building locations and junctions Now junctions are built using the following methods: ```rust let location = Location { parents: 1, interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into() }; ``` or ```rust let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]); ``` And they are matched like so: ```rust match location.unpack() { (1, [Parachain(id)]) => ... (0, Here) => ..., (1, [_]) => ..., } ``` This syntax is mandatory in v4, and has been also implemented for v2 and v3 for easier migration. This was needed to make all sizes smaller. # TODO - [x] Scaffold v4 - [x] Port github.com/paritytech/polkadot/pull/7236 - [x] Remove `Multi` prefix - [x] Remove `Abstract` asset id --------- Co-authored-by: command-bot <> Co-authored-by:

Adds the `authorize_upgrade` -> `enact_authorized_upgrade` pattern to `frame-system`. This will be useful for upgrading bridged chains that are under the governance of Polkadot without passing entire runtime Wasm blobs over a bridge. Notes: - Changed `enact_authorized_upgrade` to `apply_authorized_upgrade`. Personal opinion, "apply" more accurately expresses what it's doing. Can change back if outvoted. - Remove `check_version` in favor of two extrinsics, so as to make _checked_ the default. - Left calls in `parachain-system` and marked as deprecated to prevent breaking the API. They just call into the `frame-system` functions. - Updated `frame-system` benchmarks to v2 syntax. --------- Co-authored-by: command-bot <>

In the move from the old `Currency` traits to the new `fungible/s` family of traits, we already had the `FungiblesAdapter` and `NonFungiblesAdapter` for multiple fungible and non fungible assets respectively. However, for handling only one fungible asset, we were missing a `FungibleAdapter`, and so used the old `CurrencyAdapter` instead. This PR aims to fill in that gap, and provide the new adapter for more updated examples. I marked the old `CurrencyAdapter` as deprecated as part of this PR, and I'll change it to the new `FungibleAdapter` in a following PR. The two stages are separated so as to not bloat this PR with some name fixes in tests. --------- Co-authored-by: command-bot <>

## Summary This pull request proposes a solution for improved control of the versioned XCM flow over the bridge (across different consensus chains) and resolves the situation where the sending chain/consensus has already migrated to a higher XCM version than the receiving chain/consensus. ## Problem/Motivation The current flow over the bridge involves a transfer from AssetHubRococo (AHR) to BridgeHubRococo (BHR) to BridgeHubWestend (BHW) and finally to AssetHubWestend (AHW), beginning with a reserve-backed transfer on AHR. In this process: 1. AHR sends XCM `ExportMessage` through `XcmpQueue`, incorporating XCM version checks using the `WrapVersion` feature, influenced by `pallet_xcm::SupportedVersion` (managed by `pallet_xcm::force_xcm_version` or version discovery). 2. BHR handles the `ExportMessage` instruction, utilizing the latest XCM version. The `HaulBlobExporter` converts the inner XCM to [`VersionedXcm::from`](https://github.com/paritytech/polkadot-sdk/blob/63ac2471aa0210f0ac9903bdd7d8f9351f9a635f/polkadot/xcm/xcm-builder/src/universal_exports.rs#L465-L467), also using the latest XCM version. However, challenges arise: - Incompatibility when BHW uses a different version than BHR. For instance, if BHR migrates to **XCMv4** while BHW remains on **XCMv3**, BHR's `VersionedXcm::from` uses `VersionedXcm::V4` variant, causing encoding issues for BHW. ``` /// Just a simulation of possible error, which could happen on BHW /// (this code is based on actual master without XCMv4) let encoded = hex_literal::hex!("0400"); println!("{:?}", VersionedXcm::<()>::decode(&mut &encoded[..])); Err(Error { cause: None, desc: "Could not decode `VersionedXcm`, variant doesn't exist" }) ``` - Similar compatibility issues exist between AHR and AHW. ## Solution This pull request introduces the following solutions: 1. **New trait `CheckVersion`** - added to the `xcm` module and exposing `pallet_xcm::SupportedVersion`. This enhancement allows checking the actual XCM version for desired destinations outside of the `pallet_xcm` module. 2. **Version Check in `HaulBlobExporter`** uses `CheckVersion` to check known/configured destination versions, ensuring compatibility. For example, in the scenario mentioned, BHR can store the version `3` for BHW. If BHR is on XCMv4, it will attempt to downgrade the message to version `3` instead of using the latest version `4`. 3. **Version Check in `pallet-xcm-bridge-hub-router`** - this check ensures compatibility with the real destination's XCM version, preventing the unnecessary sending of messages to the local bridge hub if versions are incompatible. These additions aim to improve the control and compatibility of XCM flows over the bridge and addressing issues related to version mismatches. ## Possible alternative solution _(More investigation is needed, and at the very least, it should extend to XCMv4/5. If this proves to be a viable option, I can open an RFC for XCM.)._ Add the `XcmVersion` attribute to the `ExportMessage` so that the sending chain can determine, based on what is stored in `pallet_xcm::SupportedVersion`, the version the destination is using. This way, we may not need to handle the version in `HaulBlobExporter`. ``` ExportMessage { network: NetworkId, destination: InteriorMultiLocation, xcm: Xcm<()> destination_xcm_version: Version, // <- new attritbute }, ``` ``` pub trait ExportXcm { fn validate( network: NetworkId, channel: u32, universal_source: &mut Option<InteriorMultiLocation>, destination: &mut Option<InteriorMultiLocation>, message: &mut Option<Xcm<()>>, destination_xcm_version: Version, , // <- new attritbute ) -> SendResult<Self::Ticket>; ``` ## Future Directions This PR does not fix version discovery over bridge, further investigation will be conducted here: https://github.com/paritytech/polkadot-sdk/issues/2417. ## TODO - [x] `pallet_xcm` mock for tests uses hard-coded XCM version `2` - change to 3 or lastest? - [x] fix `pallet-xcm-bridge-hub-router` - [x] fix HaulBlobExporter with version determination [here](https://github.com/paritytech/polkadot-sdk/blob/2183669d05f9b510f979a0cc3c7847707bacba2e/polkadot/xcm/xcm-builder/src/universal_exports.rs#L465) - [x] add unit-tests to the runtimes - [x] run benchmarks for `ExportMessage` - [x] extend local run scripts about `force_xcm_version(dest, version)` - [ ] when merged, prepare governance calls for Rococo/Westend - [ ] add PRDoc Part of: https://github.com/paritytech/parity-bridges-common/issues/2719 --------- Co-authored-by: command-bot <>

This PR introduces a script and some templates to use the prdoc involved in a release and build: - the changelog - a simple draft of audience documentation Since the prdoc presence was enforced in the middle of the version 1.5.0, not all PRs did come with a `prdoc` file. This PR creates all the missing `prdoc` files with some minimum content allowing to properly generate the changelog. The generated content is **not** suitable for the audience documentation. The audience documentation will be possible with the next version, when all PR come with a proper `prdoc`. ## Assumptions - the prdoc files for release `vX.Y.Z` have been moved under `prdoc/X.Y.Z` - the changelog requires for now for the prdoc files to contain author + topic. Thos fields are optional. The build script can be called as: ``` VERSION=X.Y.Z ./scripts/release/build-changelogs.sh ``` Related: - #1408 --------- Co-authored-by:

As suggested in this thread: https://github.com/polkadot-fellows/runtimes/pull/87#discussion_r1400237122 We already have the `IsChildSystemParachain`, which may be used at relay chain, but it can't be used at a parachain level. So let's use `AllSiblingSystemParachains` for that. I was thinking about `AllSystemParachains`, but it may cause wrong impression that it can be used at a relay chain level. --------- Co-authored-by:

# Motivation (+testing) ### Enable easy `ForeignAssets` transfers using `pallet-xcm` We had just previously added capabilities to teleport fees during reserve-based transfers, but what about reserve-transferring fees when needing to teleport some non-fee asset? This PR aligns everything under either explicit reserve-transfer, explicit teleport, or this new flexible `transfer_assets()` which can mix and match as needed with fewer artificial constraints imposed to the user. This will enable, for example, a (non-system) parachain to teleport their `ForeignAssets` assets to AssetHub while using DOT to pay fees. (the assets are teleported - as foreign assets should from their owner chain - while DOT used for fees can only be reserve-based transferred between said parachain and AssetHub). Added `xcm-emulator` tests for this scenario ^. # Description Reverts `(limited_)reserve_transfer_assets` to only allow reserve-based transfers for all `assets` including fees. Similarly `(limited_)teleport_assets` only allows teleports for all `assets` including fees. For complex combinations of asset transfers where assets and fees may have different reserves or different reserve/teleport trust configurations, users can use the newly added `transfer_assets()` extrinsic which is more flexible in allowing more complex scenarios. `assets` (excluding `fees`) must have same reserve location or otherwise be teleportable to `dest`. No limitations imposed on `fees`. - for local reserve: transfer assets to sovereign account of destination chain and forward a notification XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for destination reserve: burn local assets and forward a notification to `dest` chain to withdraw the reserve assets from this chain's sovereign account and deposit them to `beneficiary`. - for remote reserve: burn local assets, forward XCM to reserve chain to move reserves from this chain's SA to `dest` chain's SA, and forward another XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for teleports: burn local assets and forward XCM to `dest` chain to mint/teleport assets and deposit them to `beneficiary`. ## Review notes Only around 500 lines are prod code (see `pallet_xcm/src/lib.rs`), the rest of the PR is new tests and improving existing tests. --------- Co-authored-by: command-bot <>

## Overview This PR aligns the `spec_version` formatting to the [recent changes](https://github.com/polkadot-fellows/runtimes/pull/26/files#diff-efa4caeb17487ecb13d8f5eb7863c3241d84afa2e73fbf25909a2ca89df0f362R142 ) made for the Polkadot/Kusama runtimes. It also backports the latest version `v1.4.0` bumps as `1_004_000`. ## Details During the switch from `v0.9` to `v1.x`, the format of the `spec_version` was modified from: `(M)m_ppp` for a runtime considered on version `M.m.pp`. For instance `0.9.42` had a `spec_version` of `9420`. With the transition to `v1.x`, the format was changed to a bigger number (still `u32`) formatted as `MM_mm_ppp` where `1.2.3` would be stored as `01_02_003`. This PR aligns the format with that has been introduced in the fellowship repo: `MMM_mmm_ppp`. --------- Co-authored-by:

This PR fixes two things: - relax `force_default_xcm_version` for testnet system parachains (e.g. BridgeHubWestend has now 2 and there is no way to change it to 3, so we need to call `force_xcm_version(3)` for every parachain that it is connected to, because we send XCMv3 messages) - add `Storage` item to `PolkadotXcm` pallet definition (now we cannot see storage items for `pallet_xcm` in PJS) ## TODO - [ ] when merged open PR to `polkadot-fellows/runtimes` repo
