C++ vs. C. + + Our goal is to smooth this transition, with backward compatibility + and automatic update paths, while still progressing toward SimGrid4. + + SimGrid remains open during works: The last pure SimGrid3 release was + v3.12 while all subsequent versions are usable alpha versions of + SimGrid4: Existing interfaces remain unchanged, but the new S4U + interface is budding and the internals are deeply reorganized. + + Since 2015, we work hard to reduce the changes to public APIs. When + we need to rename a public library symbol in S4U, we let your + compiler issue an explicative warning when you use the deprecated + function. These messages remain for four releases, i.e. for one full + year, before turning into an error. Starting with v3.15, your can + also adapt to API changes with the SIMGRID_VERSION macro, that is + defined to 31500 for v3.15, to 31901 for v3.19.1 and so on. + + Starting with this v3.19.1, our commitment to reduce the changes to + the public interfaces is extended from the API to the ABI: a program + using only MSG or SimDag and compiled against a given version of + simgrid can probably be used with a later version of SimGrid without + recompilation. We will do our best... but don't expect too much of + it, that's a really difficult goal during such profund refactoring. + + The difference between v3.19 and v3.19.1 is that the former was + accidentally breaking the ABI of MSG, while the later is restoring + the previous ABI. + + S4U and kernel APIs will still evolve until SimGrid4, with one-year + deprecation warnings as currently. In fact, cleaning up these + interfaces and converting them to snake_case() is one release goal of + v3.20.
