This section describes our version policy for SearchStax-hosted Apache Solr. SearchStax reserves the right to update or change this policy time to time.
Apache Solr versions are denoted as X.Y.Z, where X is the major version, Y is the minor version, and Z is the patch level or maintenance release (version 6.4.2, for example). You can learn more about it here: http://lucene.apache.org/solr/community.html
We make the two latest minor versions of the latest major version available for provisioning. In addition, the latest minor version of the previous major version is also available
Previous maintenance releases are removed as new ones becomes available. Only the latest maintenance release within an available minor version is available.
You might sometimes see additional versions listed in the user interface beyond what we guarantee to be available. If a version is listed in the SearchStax Dashboard, it can be deployed
When a new Apache Solr version is released, we do our best to provide the new version in SearchStax Cloud within 4 weeks. We notify you of a new release and recommend an upgrade. You’ll need to decide whether to upgrade to the new version with new features and bug fixes or to stay with a version you know works for you a while longer.
There can be changes in new major versions of Apache Solr that will break what used to work in older versions. Before upgrading, you’ll want to check if the new version introduces any changes that might affect your applications. If you have an application that depends on the deprecated capability, the application will need to be updated to continue working with the new version of Apache Solr.
To learn more about upgrading to newer versions of the Apache Solr on our hosted service, contact our support team support@searchstax.com
We reserve the right to force upgrade a cluster immediately and without notice in advance if there is a critical security or stability issue. Such upgrades happen only within minor versions.
A forced upgrade might become necessary in a situation that:
We follow the Apache Solr official end-of-life (EOL) policy for the SearchStax-hosted Apache Solr. This means that we provide support for each major release of Apache Solr and the last minor release of the two most recent major releases of Apache Solr.
e.g.
| Version | Description |
|---|---|
| v7.2.1 | Current Version – Supported by SearchStax Hosting Services |
| v6.4 | One Major Version Prior to Current Version – Supported by SearchStax Hosting Services |
| v5.5 | Two Major Versions Prior to Current Version – Supported by SearchStax Hosting Services |
| v4.10 | Three Major Versions Prior to Current Version – Not Supported |
We give you six months advance notice before a minor version nears its end-of-life, effectively providing you with six month’s time to upgrade to a newer version yourself. Notice is given by email to the contacts registered in the SearchStax Dashboard.
If you do not upgrade to an available newer minor version by the end-of-life date, you will be force upgraded to the latest available minor version within your current major version.
For Gold and above subscriptions, we communicate with you through a support case and attempt to perform the upgrade in coordination with you.
For Standard subscriptions, we notify you by email and provide a deadline by which the upgrade will happen if you do not upgrade your cluster yourself.
We do not force upgrade across major versions. For major versions that reach end-of-life:
