### New features
* Proxies: added the proxy contracts from OpenZeppelin SDK. ([#2335](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/2335))
#### Proxy changes with respect to OpenZeppelin SDK
Aside from upgrading them from Solidity 0.5 to 0.6, we've changed a few minor things from the proxy contracts as they were found in OpenZeppelin SDK.
- `UpgradeabilityProxy` was renamed to `UpgradeableProxy`.
- `AdminUpgradeabilityProxy` was renamed to `TransparentUpgradeableProxy`.
- `Proxy._willFallback` was renamed to `Proxy._beforeFallback`.
- `UpgradeabilityProxy._setImplementation` and `AdminUpgradeabilityProxy._setAdmin` were made private.
### Improvements
* `Address.isContract`: switched from `extcodehash` to `extcodesize` for less gas usage. ([#2311](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/2311))
