 //! [This](https://github.com/paritytech/polkadot-sdk/issues/5565) future improvement to OmniNode
 //! aims to make such checks automatic.
 //!
+//! ### Runtime conventions
+//!
+//! The Omni Node needs to make some assumptions about the runtime. During startup, the node fetches
+//! the runtime metadata and asserts that the runtime represents a compatible parachain.
+//! The checks are best effort and will generate warning level logs in the Omni Node log file on
+//! failure.
+//!
+//! The list of checks may evolve in the future and for now only few rules are implemented:
+//! * runtimes must define a type for [`cumulus-pallet-parachain-system`], which is recommended to
+//!   be named as `ParachainSystem`.
+//! * runtimes must define a type for [`frame-system`] pallet, which is recommended to be named as
+//!   `System`. The configured [`block number`] here will be used by Omni Node to configure AURA
+//!   accordingly.

+    Fix the broker pallet auto-renew benchmarks which have been broken since #4424, yielding `Weightless` due to some prices being set too low, as reported in #6474.

+title: 'pallet_revive: Switch to 64bit RISC-V'
+doc:
+- audience: Runtime Dev
+  description: |-
+    This PR updates pallet_revive to the newest PolkaVM version and adapts the test fixtures and syscall interface to work under 64bit.
+
+    Please note that after this PR no 32bit contracts can be deployed (they will be rejected at deploy time). Pre-deployed 32bit contracts are now considered defunct since we changes how parameters are passed for functions with more than 6 arguments.
+
+    ## Fixtures
+
+    The fixtures are now built for the 64bit target. I also removed the temporary directory mechanism that triggered a full rebuild every time. It also makes it easier to find the compiled fixtures since they are now always in `target/pallet-revive-fixtures`.
+
+    ## Syscall interface
+
+    ### Passing pointer
+
+    Registers and pointers are now 64bit wide. This allows us to pass u64 arguments in a single register. Before we needed two registers to pass them. This means that just as before we need one register per pointer we pass. We keep pointers as `u32` argument by truncating the register. This is done since the memory space of PolkaVM is 32bit.
+
+    ### Functions with more than 6 arguments
+
+    We only have 6 registers to pass arguments. This is why we pass a pointer to a struct when we need more than 6. Before this PR we expected a packed struct and interpreted it as SCALE encoded tuple. However, this was buggy because the `MaxEncodedLen` returned something that was larger than the packed size of the structure. This wasn't a problem before. But now the memory space changed in a way that things were placed at the edges of the memory space and those extra bytes lead to an out of bound access.
+
+    This is why this PR drops SCALE and expects the arguments to be passed as a pointer to a `C` aligned struct. This avoids unaligned accesses. However, revive needs to adapt its codegen to properly align the structure fields.
+
+    ## TODO
+    - [ ] Add multi block migration that wipes all existing contracts as we made breaking changes to the syscall interface

+title: Added fallback_max_weight to Transact for sending messages to V4 chains
+doc:
+- audience: Runtime Dev
+  description: |-
+    Removing the `require_weight_at_most` parameter in V5 Transact introduced a problem when converting a message from V5 to V4 to send to chains that didn't upgrade yet.
+    The local chain doesn't know how to decode calls for remote chains so it can't automatically populate `require_weight_at_most` required by V4 Transact.
+    To fix this, XCM v5 Transact now also takes a `fallback_max_weight: Option<Weight>` parameter.
+    This can be set to `None` if the instruction is not meant to be sent to chains running XCM versions lower than V5.
+    If set to `Some(weight)`, a subsequent conversion to V4 will result in `Transact { require_weight_at_most: weight, .. }`.
+    The plan is to remove this workaround in V6 since there will be a good conversion path from V6 to V5.

+doc:

+    description: |
+      `polkadot-omni-node` lib supports `--dev` flag now by allowing also to pass over a chain spec,
+      and starts the node with manual seal. It will seal the node at each `dev_block_time` milliseconds,
+      which can be set via `--dev-block-time`, and if not set will default to `3000ms`.

+title: Fix runtime api impl detection by construct runtime
+doc:
+- audience: Runtime Dev
+  description: |-
+    Construct runtime uses autoref-based specialization to fetch the metadata about the implemented runtime apis. This is done to not fail to compile when there are no runtime apis implemented. However, there was an issue with detecting runtime apis when they were implemented in a different file. The problem is solved by moving the trait implemented by `impl_runtime_apis!` to the metadata ir crate.

+title: 'pallet-revive: Adjust error handling of sub calls'
+doc:
+- audience: Runtime Dev
+  description: |-
+    We were trapping the host context in case a sub call was exhausting the storage deposit limit set for this sub call. This prevents the caller from handling this error. In this PR we added a new error code that is returned when either gas or storage deposit limit is exhausted by the sub call.
+
+    We also remove the longer used `NotCallable` error. No longer used because this is no longer an error: It will just be a balance transfer.
+
+    We also make `set_code_hash` infallible to be consistent with other host functions which just trap on any error condition.

+title: 'pallet-revive: Statically verify imports on code deployment'
+doc:
+- audience: Runtime Dev
+  description: |-
+    Previously, we failed at runtime if an unknown or unstable host function was called. This requires us to keep track of when a host function was added and when a code was deployed. We used the `api_version` to track at which API version each code was deployed. This made sure that when a new host function was added that old code won't have access to it. This is necessary as otherwise the behavior of a contract that made calls to this previously non existent host function would change from "trap" to "do something".
+
+    In this PR we remove the API version. Instead, we statically verify on upload that no non-existent host function is ever used in the code. This will allow us to add new host function later without needing to keep track when they were added.
+
+    This simplifies the code and also gives an immediate feedback if unknown host functions are used.

+    The `debug` level in `sc-basic-authorship`  is now less spammy. Previously it was outputing logs per individual transactions. It made quite hard to follow the logs (and also generates unneeded traffic in grafana).
+
+    Now debug level only show some internal details, without spamming output with per-transaction logs. They were moved to `trace` level.
+
+    I also added the `EndProposingReason` to the summary INFO message. This allows us to know what was the block limit (which is very useful for debugging).

+    With [permissionless lanes PR#4949](https://github.com/paritytech/polkadot-sdk/pull/4949), the congestion mechanism based on sending `Transact(report_bridge_status(is_congested))` from `pallet-xcm-bridge-hub` to `pallet-xcm-bridge-hub-router` was replaced with a congestion mechanism that relied on monitoring XCMP queues. However, this approach could cause issues, such as suspending the entire XCMP queue instead of isolating the affected bridge. This PR reverts back to using `report_bridge_status` as before.

+title: Add aliasers to westend chains
+doc:
+- audience: Runtime Dev
+  description: |-
+    `InitiateTransfer`, the new instruction introduced in XCMv5, allows preserving the origin after a cross-chain transfer via the usage of the `AliasOrigin` instruction. The receiving chain needs to be configured to allow such this instruction to have its intended effect and not just throw an error.
+
+    In this PR, I add the alias rules specified in the [RFC for origin preservation](https://github.com/polkadot-fellows/RFCs/blob/main/text/0122-alias-origin-on-asset-transfers.md) to westend chains so we can test these scenarios in the testnet.
+
+    The new scenarios include:
+    - Sending a cross-chain transfer from one system chain to another and doing a Transact on the same message (1 hop)
+    - Sending a reserve asset transfer from one chain to another going through asset hub and doing Transact on the same message (2 hops)
+
+    The updated chains are:
+    - Relay: added `AliasChildLocation`
+    - Collectives: added `AliasChildLocation` and `AliasOriginRootUsingFilter<AssetHubLocation, Everything>`
+    - People: added `AliasChildLocation` and `AliasOriginRootUsingFilter<AssetHubLocation, Everything>`
+    - Coretime: added `AliasChildLocation` and `AliasOriginRootUsingFilter<AssetHubLocation, Everything>`
+
+    AssetHub already has `AliasChildLocation` and doesn't need the other config item.
+    BridgeHub is not intended to be used by end users so I didn't add any config item.
+    Only added `AliasChildOrigin` to the relay since we intend for it to be used less.

+## Runtime development
+
+We recommend using [`chopsticks`](https://github.com/AcalaNetwork/chopsticks) when the focus is more on the runtime
+development and `OmniNode` is enough as is.
+
+### Install chopsticks
+
+To use `chopsticks`, please install the latest version according to the installation [guide](https://github.com/AcalaNetwork/chopsticks?tab=readme-ov-file#install).
+
+### Build a raw chain spec
+
+Build the `parachain-template-runtime` as mentioned before in this guide and use `chain-spec-builder`
+again but this time by passing `--raw-storage` flag:
+
+```sh
+chain-spec-builder create --raw-storage --relay-chain "rococo-local" --para-id 1000 --runtime \
+    target/release/wbuild/parachain-template-runtime/parachain_template_runtime.wasm named-preset development

+
+### Start `chopsticks` with the chain spec
+
+```sh
+npx @acala-network/chopsticks@latest --chain-spec <path/to/chain_spec.json>
+```
+
+### Alternatives
+
+`OmniNode` can be still used for runtime development if using the `--dev` flag, while `parachain-template-node` doesn't
+support it at this moment. It can still be used to test a runtime in a full setup where it is started alongside a
+relay chain network (see [Parachain Template node](#parachain-template-node) setup).
