Changelog

0.2.1
-----
0.3.0
-----
Patch release (day 5 part 2).
Minor release (day 7 part 1-2).
- Add operation 5: set instruction pointer to value at parameter 2 position, based on value at parameter 1 position
- Add operation 6: set instruction pointer to value at parameter 2 position, based on value at parameter 1 position
- Add operation 7: compares values in parameter 1 position and parameter 2 position, stores at parameter 3 position
- Add operation 8: compares values in parameter 1 position and parameter 2 position, stores at parameter 3 position
BREAKING CHANGE: execute() now returns 4 values.
- now: exit code, state at halt, instruction position at halt, and captured stdout.
- before: final state, and captured stdout
0.2.0
-----
Changes:
Minor release (day 5 part 1).
- Add support for a sequence of stdins
- Add interactive param to ask for manual (interactive) input on input opcode
- Add verbose param to show more output in interactive input mode
- Will now halt with code 3 (input) when input is required, stdin is empty and interactive input mode is not enabled
- Support immediate parameter mode
- Add stdin argument
- Make arguments optional: noun, verb
- Capture and return stdout
- Add operation 3: store stdin to parameter 1 position
- Add operation 4: output value at parameter 1 position to stdout

- Add operation 8: compares values in parameter 1 position and parameter 2 position, stores at parameter 3 position
- Remove initial modification 1=12, 2=2
- Add noun argument, stored at pos 1 (default value: 12)
- Add verb argument, stored at pos 2 (default value: 2)
