CppNix 2.3 was released in 2019, and is the new oldest supported version. We
|
||
|
|
will increase our support baseline in the future up to a final version of CppNix
|
||
|
|
2.18 (which may happen soon given that it is the only still-packaged and thus
|
||
|
|
still-tested >2.3 version), but this step already removes a significant amount
|
||
|
|
of dead, untested, code paths.
|
||
|
|
|
||
|
|
Lix speaks the same version of the protocol as CppNix 2.18 and that fact will
|
||
|
|
never change in the future; the Lix plans to replace the protocol for evolution
|
||
|
|
will entail a complete incompatible replacement that will be supported in
|
||
|
|
parallel with the old protocol. Lix will thus retain remote build compatibility
|
||
|
|
with CppNix as long as CppNix maintains protocol compatibility with 2.18, and
|
||
|
|
as long as Lix retains legacy protocol support (which will likely be a long
|
||
|
|
time given that we plan to convert it to a frozen-in-time shim).
