Normally, there shouldn't be a need to break compatibility this way, but the mining interface has evolved a lot since it was first introduced, with old clients using the original methods less stable and performant than newer clients. So now is a good time to introduce a cutoff, drop deprecated methods, and stop supporting old clients which can't function as well. Bumping the field number is also an opportunity to make other improvements that would be awkward to implement compatibly: - Making Cap'n Proto default parameter and field values match default values of corresponding C++ methods and structs. - Adding missing Context parameters to Mining.createNewBlock and checkBlock methods so these methods will be executed on separate execution threads and not block the Cap'n Proto event loop thread. More details about these changes are in the commit messages.

src/node/
The src/node/ directory contains code that needs to access node state
(state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar
classes).
Code in src/node/ is meant to be segregated from code in
src/wallet/ and src/qt/, to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the src/node/,
src/wallet/, or src/qt/ directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/ classes.
This directory is at the moment
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
