• Complete the WDC 65C02 instruction set implementation by @mre in #121
• Add interrupt handling with vector constants and documentation by @mre in #122
• Add cycle times by @mre in #124
• Support for illegal opcodes by @omarandlorraine and @mlund in #126

Full Changelog: v0.7.0...v.0.8.0

We finally pass the functional test from https://github.com/Klaus2m5/6502_65C02_functional_tests, which is a big milestone as it means the emulator handles all default instructions correctly.
