* Fixed logic of the storage migration to triple reference counting. The previous behaviour made it impossible for any chain not already upgraded to dual reference counting to upgrade the runtime. * +Removed the on_runtime_upgrade() function from frame-system. +Removed the specific migration .anciallaries from the frame-system pallet level. +Introducted a new module that hosts self-contained ancillary functions and logic to perform the storage migration. The current logic attempts to infer the state of the storage based on whether or not a given migration can be conducted. * Formatting. * + Removed specific AccountData struct. AccountData must now be provided during the runtime implementation of the trait V2ToV3. + Removed apply function. + Made the individual translation function self-sufficient. * + Removed unused decorators.

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
