Overview

Change license from MIT to Apache 2.0.

• I have updated LICENSE file and changed from MIT to Apache 2.0 in each file.

Comments

There is something to be confirmed here though - it concerns the following files :

lib/bech32/src/Codec/Binary/Bech32/Internal.hs
lib/bech32/bech32.cabal
lib/bech32/src/Codec/Binary/Bech32.hs

Can the license be changed if copyright is :

license:       Apache-2.0

?

Yes. The change of license only take effects at the moment you change it. So in practice, the license in 2017 & 2018 was MIT, and starting from 2019 it's Apache 2.0.
