+Situational Notes:
+- If adding functonality, write unit tests!
+- If importing a new pallet, choose a proper module index for it, and allow it in `BaseFilter`. Ensure **every** extrinsic works from front-end. If there's corresponding tool, ensure both work for each other.
+- If needed, update our Javascript/Typescript APIs. These APIs are officially used by exchanges or community developers.
+- If modifying existing runtime storage items, make sure to implement storage migrations for the runtime and test them with `try-runtime`. This includes migrations inherited from upstream changes, and you can search the diffs for modifications of `#[pallet::storage]` items to check for any.
+- If runtime changes, need to update the version numbers properly:
    * `authoring_version`: The version of the authorship interface. An authoring node will not attempt to author blocks unless this is equal to its native runtime.
    * `spec_version`: The version of the runtime specification. A full node will not attempt to use its native runtime in substitute for the on-chain Wasm runtime unless all of spec_name, spec_version, and authoring_version are the same between Wasm and native.
    * `impl_version`: The version of the implementation of the specification. Nodes are free to ignore this; it serves only as an indication that the code is different; as long as the other two versions are the same then while the actual code may be different, it is nonetheless required to do the same thing. Non-consensus-breaking optimizations are about the only changes that could be made which would result in only the impl_version changing.
-   * `transaction_version`: The version of the extrinsics interface. This number must be updated in the following circumstances: extrinsic parameters (number, order, or types) have been changed; extrinsics or pallets have been removed; or the pallet order in the construct_runtime! macro or extrinsic order in a pallet has been changed. You can run the `metadata_diff.yml` workflow for help. If this number is updated, then the `spec_version` must also be updated
