[tmiw]

Bumps version number of Codec2 to 1.0.0 and includes "make dist" changes from drowe67/freedv-gui#152.

@drowe67, were there any other PRs that should get in prior to merging this one? Also, what should LPCNet be bumped to if anything?

[drowe67]

Thanks @tmiw, nothing else I'd like to merge at this stage, Hmm, not sure about LPCNet, good question 🤔

@hobbes1069 - I think we have Codec 2 repo ready for the 1.0 release. It's been tested for a while and no further bugs have shown up.

[tmiw]

Hmm, should the stm32 fixes get in too, or is 1.0 intended to be a release just for regular PCs?

[drowe67]

I'm inclined to leave them until afterwards. We can also make a new firmware release and update the stm32 README.md

[drowe67]

@tmiw so I think we are good for a v1.0 release. Do you agree? We've had quite a bit of testing via your recent freedv-gui test releases, and it's been some time since we've found a bug in libcodec2.

If you are happy I'll merge this PR, and add a tag 🙂 ?

[tmiw]

@drowe67, sounds good. 👍
