Version control

[SyntaxColoring]

Using this ticket as a scratchpad for my scattered thoughts. Bear with me.

Problems

• We don't have easily referenceable release notes.
• We keep giving the operators similarly named files, which is confusing.
• It's not obvious, from just a filename, what is being run and what instructions should be followed.
• Me being the one person to update the docs on protocols.io is a bottleneck.

Implementation notes

• Any version counters should be started artificially high (like at 20), to avoid confusion with existing filenames like V15-StationB-8samples.py.
• Filenames should include the version identifier.
• For development, we shouldn't have to worry about bumping the version number after every little change.
• Version identifiers must be clear and easily comparable. A monotonic counter or a date is probably fine. A Git SHA1 is probably not.

Open questions

• Labware?
