= Fault Tolerance 6.9.2

Today, we announce the https://github.com/smallrye/smallrye-fault-tolerance/releases/tag/6.9.2[release] of {smallrye-ft} 6.9.2.
This release contains an important bugfix.

Since the link:/blog/fault-tolerance-6-7-2[6.7.2] and link:/blog/fault-tolerance-6-7-3/[6.7.3] releases, Vert.x worker threads are treated as event loops as well.
In case of a worker thread execution from an event loop context, the event loop integration code used to use `Context.executeBlocking()` in an ordered fashion.
This may lead to a deadlock-like situation in case the original call also occurs in an ordered `executeBlocking()` situation, because:

. the original handler that called a guarded method may wait for it to complete,
. the newly scheduled handler comes after the original handler, so has to wait for it to complete.

In this release, the issue is fixed: the event loop integration code no longer requires ordering.

As usual, if you have any ideas for improvements, please https://github.com/smallrye/smallrye-fault-tolerance/issues[file an issue]!
