In version 3 of OpenHFT's Chronicle Queue there is an API call on ExcerptAppender (nextSynchronous(boolean)) to request that the contents of the queue be forced to be written to disk (fsync'd)when the next excerpt is finished. I don't see a similar call in version 4. Is it possible to achieve the same effect with version 4?

Not at the moment. If you need guarenteed writes we suggest acknowledged replication.
I suggest you add it as a github issue, however I can't say when this will be added.

Ok, understood, but then for now we need to stay with version 3. Is there any forum these days for reporting issues with chronicle version 3? I have a stand-alone test that illustrates a problem with entries being lost on block roll-over. – Paul Bandler Jun 30 '17 at 14:38

@PaulBandler You can report these on Stackoverflow however we don't provide free support for version 3. – Peter Lawrey Jun 30 '17 at 14:41
