I am planning to use 8.8 line-up for production use.
But recently, a lot of people are complaining on 8.7 and 8.8. Also, there is a
clearly known issue on 8.8 as well.
Following trends of earlier versions (5.x, 6.x and 7.x), will 8.8 will also be
finalized?
For 5.x, 5.5.x was last version. For 6.x, 6.6.x was last version. For 7.x,
7.7.x was last version. It would match the pattern, it seems.
And 9.x is already planned and under development.
And it seems, we require some stability.
All released versions are considered stable. Sometimes problems are
uncovered after release. Sometimes BIG problems. We try our very best
to avoid bugs, but achieving that kind of perfection is nearly
impossible for any software project.
8.8.0 is the most current release. The 8.8.1 release is underway, but
there's no way I can give you a concrete date. The announcement MIGHT
come in the next few days, but it's always possible it could get pushed
back. At this time, the changelog for 8.8.1 has five bugfixes
mentioned. It should be more stable than 8.8.0, but it's impossible for
me to tell you whether you will have any problems with it.
On the dev list, the project is discussing the start of work on the 9.0
release, but that work has not yet begun. Even if it started tomorrow,
it would be several weeks, maybe even a few months, before 9.0 is
actually released. On top of the "normal" headaches involved in any new
major version release, there are some other things going on that might
further delay 9.0 and future 8.x versions:
* Solr is being promoted from a subproject of Lucene to it's own
top-level project at Apache. This involves a LOT of work. Much of that
work is administrative in nature, which is going to occupy us and take
away from time that we might spend working on the code and new releases.
* The build system for the master branch, which is currently versioned
as 9.0.0-SNAPSHOT, was recently switched from Ant+Ivy to Gradle. It's
going to take some time to figure out all the fallout from that migration.
* Some of the devs have been involved in an effort to greatly simplify
and rewrite how SolrCloud does internal management of a cluster. The
intent is much better stability and better performance. You might have
seen public messages referring to a "reference implementation." At this
time, it is unclear how much of that work will make it into 9.0 and how
much will be revealed in later releases. We would like very much to
include at least the first phase in 9.0 if we can.
From what I have seen over the last several years as one of the
developers on this project, it is likely that 8.9 and possibly even 8.10
and 8.11 will be released before we see 9.0. Releases are NOT made on a
specific schedule, so I cannot tell you which versions you will see or
when they might happen.
I am fully aware that despite typing quite a lot of text here, that I
provided almost nothing in the way of concrete information that you can
use. Sorry about that.
Thanks,
