Developers: Just released Counterpartyd 9.32.0 to develop branch. This change includes some potentially backwards incompatible changes. With this release, the entire backend engine code was switched from cherrypy to flask. this shouldn’t impact users of the API, except that some existing checks were made stronger. Specifically: if you use non-named/position arguments with any API calls, you will get an error (where before some API calls would work with positional args, but all the get\_ ones wouldn’t).
Backwards incompatible changes: [https://github.com/CounterpartyXCP/counterpartyd/blob/develop/docs/API.rst#9320](https://github.com/CounterpartyXCP/counterpartyd/blob/develop/docs/API.rst#9320)
Full changeset: [https://github.com/CounterpartyXCP/counterpartyd/commit/0cd7e3600041efff842e1abb48ba349d756713dc](https://github.com/CounterpartyXCP/counterpartyd/commit/0cd7e3600041efff842e1abb48ba349d756713dc)
If you develop against counterpartyd, please test your code against this new release. Pending no issues, we will be promoting this to master in 5 days to a week or so.

Releasing counterpartyd v9.33.0 on the develop branch in a couple of hours. This release fixes a (very) minor protocol problem with call dates and call prices. The change is retroactive and so it will require an immediate, mandatory upgrade when it is released on master. Update: This change will go into effect with block 312000, before which time the new version will be merged into master.

We should be merging v9.33.1 of counterpartyd into master tomorrow afternoon (EDT), and forcing an upgrade to it by block 312500. This upgrade includes some very minor changes to the API listed in the CHANGELOG.

There’ll be a forced upgrade to v9.34.0 with block 312350 which will temporarily disable CFDs, due to the bug described in GitHub Issue #191.

There'll be a forced upgrade to v9.35.0 with block 313800 (about two days from now) which will tweak BTC order matching and BTCpay logic. No changes were made to the API.
EDIT: Make that v9.36.0.

Some of these optimizations have to be rolled back: v9.38.0 will be mandatory by block 314250 (24 hours from now). The upgrade should be perfectly straightforward.
