  3. Introduction • A server is a hardware or program that is used to provide functionality through the client-server model, over a network, to clients which are either other devices or other programs. This functionality could be services, data, programs, or resources. Servers are of many types, such as file servers, database servers, print servers, mail servers, application servers, web servers, etc. Web servers are used for providing the service of web hosting, by all the hosting service providers, including companies that are famous as the “Best Cloud Hosting Company”, the “Best Windows Hosting Company”, the “Best Website Hosting Company”, etc. Web servers store the files of websites and deliver these over the Internet to the Internet-connected devices for making websites accessible. Hence, web servers play a crucial part in web hosting, the service that makes websites accessible and keeps them up and running without any issue. • Here, we will help you make decisions regarding updating your server. For this, it is important that you understand the versions and releases of cPanel & WHM. It needs to be mentioned here that you cannot downgrade a cPanel & WHM installation between major versions or release tiers. • Let us proceed with our topic.

  4. Version Numbers A cPanel & WHM version number has 3 or 4 incremented integer values. Each of these values is separated from the other with a period (.) The below-mentioned parts are present in every version number. • Parent Value • Major Value • Minor Value • Build Value Let us discuss each of these individually in the next few slides.

  5. Parent Value • The parent value is from a previous version numbering system of cPanel & WHM. A large group of major versions of cPanel & WHM are indicated by it. This part of the numbering system with regard to cPanel & WHM had been deprecated in the version 11.52. This value is optional in most cases. This is usually seen in configuration files, RPM files, and API function output.

  6. Major Value • A new set of features is indicated by each major value. The builds in it are frequently referred to as a release or a major version. • Those development releases which appear on the EDGE release tier are known as the odd major values. The production releases which appear in all release tiers are referred to as even major values.

  7. Minor Value • It needs to be mentioned here that the minor value might be omitted in some references to version numbers. Sets of bug fixes as well as certain changes that are meant for stabilizing the features of the major value version, are indicated by the minor value. A minor value of 0 is used by the initial builds of a production release. The build value is incremented by the production release’s later publications.

  8. Build Value • The build value might be omitted by some references to version numbers. The unique build of cPanel & WHM is indicated by the build value.

  10. Releases Versions of cPanel & WHM are released across several architectures. Its several versions might be published across different tiers on the same day. Let us run you through the most recent cPanel & WHM release versions, in brief. • cPanel & WHM Version 90 – Its approximate release date was August 2020. • cPanel & WHM Version 92 – Its approximate release date was November 2020. • cPanel & WHM Version 94 (LTS) – Its approximate release date was February 2021. • cPanel & WHM Version 96 – Its approximate release date was March 2021. • cPanel & WHM Version 98 – Its approximate release date was August 2021. It needs to be noted here that if the RELEASE, STABLE, or LTS tiers are used by a server, then a delay of many business days is applied by the system, prior to an automatic upgrade taking place. Usually it is ensured that new versions do not get released on international holidays and on weekends, which exist from Thursday evening through Sunday afternoon.

  11. Release Tiers cPanel & WHM is released through 5 tiers that are publicly-available. This proves to be helpful for server owners with regard to selecting the update frequency that they prefer in the context of new versions of cPanel & WHM being developed and published. Regarding the release tiers, here are a few important points: • A release of cPanel & WHM becomes unsupported when it doesn’t exist in any tier any more and reaches EOL (End of Life). Versions that are unsupported do not receive bug fixes or security updates. • Each time that a cPanel & WHM version is about to reach its EOL, you shall receive notification about it through email. It needs to be mentioned that the releases are not EOL until the RELEASE tier is reached by the upcoming version. • The Update Preferences interface of WHM needs to be used for selecting a release tier. WHM >> Home >> Server Configuration >> Update Preferences The release tiers from which you can choose shall be discussed next.

  12. LTS • This tier can be used for selecting a single cPanel & WHM version for that particular year for which it is supported by cPanel L.L.C. Only one LTS version is shipped in each year. Security as well as other critical updates are provided by cPanel L.L.C. over the entire lifespan of any LTS release. New features are not added to LTS releases unless these are extremely critical. Updates related to compatibility with later versions are also provided. A single release per year qualifies for LTS. For the other versions, updates will be received only in the STABLE, RELEASE, CURRENT, or in the EDGE tiers.

  13. LTS Support The below-mentioned guidelines are followed for providing LTS support. • A version’s LTS period might be extended by cPanel L.L.C. at its discretion. • Each release’s lifespan extends through March 31 of the next year. • The lifespan of an LTS version is not calculated based on its publication date. • The development releases of cPanel & WHM do not qualify for LTS.

  14. LTS Updates for Other Applications LTS Updates are provided for the below-mentioned applications. • Third-Party Applications – Many third-party applications are provided by cPanel & WHM. Critical updates are provided for third-party applications of supported LTS releases. These might be provided as backported patches rather than upgrades. • EasyApache – EasyApache is released separately from the release schedule of cPanel & WHM, by cPanel L.L.C. EasyApache updates are provided for an LTS release until the release reaches its EOL. EasyApache updates the LTS version, when it doesn’t meet the requirements of EasyApache. Such an update cannot be supported by cPanel L.L.C. The php.net supported versions timeline is used by the EasyApache. RPMs for those versions of PHP, which are unsupported, remain on the mirrors and servers of cPanel L.L.C. No further updates are provided. • cPAddons and WHM Plugins – Updates related to cPAddons and WHM plugins are released throughout the lifetime of LTS release.

  15. STABLE • This tier is published less often than RELEASE. This version has been through testing, public exposure and verification.

  16. RELEASE • It needs to be mentioned that any new installation defaults to this tier. This version has been tested thoroughly. All the features and functionality that are intended, are present in it and this version is feature-complete. This tier is published more often than the STABLE one.

  17. CURRENT • This tier is published more often than the RELEASE tier. Verification and testing has happened for the CURRENT version. The “Release Candidate” tier used by the other publication schedules is represented by this tier. Some of the features of this version might be in development.

  18. EDGE • EDGE should be used for testing that is carried out in a controlled environment as EDGE builds have a dynamic nature. This tier isn’t recommended for production servers. This version has been through only rudimentary testing. This tier is published as frequently as several times in a week. • Those features are present in this version that are supposed to be changed further. Moreover, this version might not include all the features or official public documentation.

  19. Production Release Process The below-mentioned process is used for developing and managing production releases. • The development and testing of the production release is completed. • The release to the development and EDGE tiers is published. • The release to the CURRENT tier is published. At this juncture, the development and publishing of non-critical changes related to the releases is stopped. • Any immediate maintenance related requirements are assessed post the release entering the RELEASE tier. • Publishing to the STABLE and annual LTS tiers happens after the maintenance related issues get resolved. Additionally, the following points need to be mentioned, in no particular order: • Apart from everything from the previous production release, the development releases of cPanel & WHM include changes that have to do with the next planned production release. • All development release changes are published to the EDGE tier.
