Rebus versions - rebus-org/Rebus GitHub Wiki

For historical reasons, there's something called "Rebus 1" (which is NuGet package versions <= 0.84.0), and there's something called "Rebus 2" (which is NuGet package versions >= 0.90.0).

"Rebus 1" and "Rebus 2" are NOT wire-compatible. "Rebus 2" is wire-compatible with all subsequent versions though, so if you're using NuGet package version 5, your endpoint can also communicate with endpoints of versions 4, 3, and 2(*).

Here's a table that gives an overview of the version history so far.

(*) There's a caveat to this rule though: While all Rebus 2 versions use the same wire-level format (which is mostly about how message headers are used), each particular TRANSPORT might still impose some breaking changes. Most of them don't, but e.g. the SQL Transport has seen a breaking change from version 4 to 5, because it went from a single-table layout to a table-per-queue layout.
