# Polkadot Upgrade 2.0.5

Highlights of the [full CHANGELOG](https://github.com/polkadot-fellows/runtimes/releases/tag/v2.0.5):
- Capped Issuance
- Solidity Smart Contracts
- Two seconds block time on Hub

## Elastic Scaling

Hub needs three cores for its 2 seconds block times. This was done on [Kusama](https://hackmd.io/sky8Y81_SIeYprc8fnSi5g) already.

Problem:

Governance can only assign a core with `Broker::force_reserve` for the next cycle but we do not want to wait that long. This is because of a bug in `force_reserve` (see comment).

Solution:
- Acquire two cores now (buy or beg)
- Assign them to PAH
- Renew them in the next cycle
- Wait for the `force_reserve` from the 2.0.5 upgrade
- Do not renew the cores anymore

## Reproduction
