Closes https://github.com/paritytech/polkadot-sdk-docs/issues/55 - Changes 'current storage version' terminology to less ambiguous 'in-code storage version' (suggestion by @ggwpez) - Adds a new example pallet `pallet-example-single-block-migrations` - Adds a new reference doc to replace https://docs.substrate.io/maintain/runtime-upgrades/ (temporarily living in the pallet while we wait for developer hub PR to merge) - Adds documentation for the `storage_alias` macro - Improves `trait Hooks` docs - Improves `trait GetStorageVersion` docs - Update the suggested patterns for using `VersionedMigration`, so that version unchecked migrations are never exported - Prevents accidental usage of version unchecked migrations in runtimes https://github.com/paritytech/substrate/pull/14421#discussion_r1255467895 - Unversioned migration code is kept inside `mod version_unchecked`, versioned code is kept in `pub mod versioned` - It is necessary to use modules to limit visibility because the inner migration must be `pub`.

Scheduler
A module for scheduling dispatches.
Overview
This module exposes capabilities for scheduling dispatches to occur at a specified block number or at a specified period. These scheduled dispatches may be named or anonymous and may be canceled.
NOTE: The scheduled calls will be dispatched with the default filter
for the origin: namely frame_system::Config::BaseCallFilter for all origin
except root which will get no filter. And not the filter contained in origin
use to call fn schedule.
If a call is scheduled using proxy or whatever mecanism which adds filter, then those filter will not be used when dispatching the schedule call.
Interface
Dispatchable Functions
schedule- schedule a dispatch, which may be periodic, to occur at a specified block and with a specified priority.cancel- cancel a scheduled dispatch, specified by block number and index.schedule_named- augments thescheduleinterface with an additionalVec<u8>parameter that can be used for identification.cancel_named- the named complement to the cancel function.
