Important information
API support changed for Swarm 2022.2
From Swarm 2022.2, Swarm no longer supports APIs older than v9.
API version updated to v11 for Swarm 2022.1
For Swarm 2022.1, we introduced a new set of v11 APIs. These refine and extend the v10 APIs, and further standardize the endpoint and response pattern. The v10 APIs will continue to be available for some time to come
- Any improvements made in the migration to v11 will not be backported to v9 or v10.
- New API endpoints will be created as v11 and will not be backported to v9 or v10.
PHP version support changed for Swarm 2022.1
We have removed support for PHP 7.0 and 7.1 for Swarm 2022.1. This is part of our commitment to move away from using versions of platforms that have reached End-of-Life (EOL).
Swarm no longer supports Microsoft Internet Explorer
Swarm 2022.1 and later no longer supports Microsoft Internet Explorer. This is part of our commitment to move away from using platforms that have reached End-of-Life (EOL).
Swarm no longer supports CentOS 8
Swarm 2022.1 and later no longer supports Swarm installation on CentOS 8. This is part of our commitment to move away from using versions of platforms that have reached End-of-Life (EOL).
Swarm no longer supports Ubuntu 16.04
Swarm 2021.1 and later no longer supports Swarm installation on Ubuntu 16.04. This is part of our commitment to focus on supported technology platforms.

Helix Core Server 2020.1 stream spec file permissions change

Trigger script updated for Swarm 2020.1
The swarm.shelvedel shelve-del trigger script has been updated in Swarm 2020.1, the trigger script must be updated in the Helix Core Server trigger table or added if it does not already exist, see Update the Helix Core Server triggers table to run the trigger script.
Custom module support in Swarm 2020.1 and later
The Zend 3 Framework project has been forked to an open source project called Laminas, see https://getlaminas.org/about/. Swarm 2020.1 now uses the Laminas framework, this is part of our commitment to move away from using versions of platforms that have reached End-of-Life (EOL).
If you have existing custom Swarm modules created for Swarm 2019.3 or earlier, you must update them to use the Laminas framework. For instructions on updating your Zend custom modules to Laminas, see Migrate existing custom modules to the Laminas framework.
Upgrading from Swarm 2019.1 and earlier
Swarm 2019.2 introduced a Redis in-memory cache to improve performance and reduce the load on the Helix Core Server. This replaces the file-based cache that was previously used by Swarm.
On Swarm systems with a large number of users, groups, and projects, the initial population of this cache can take some time. If you have a large Swarm system you should read through the Redis server connection and configuration options before installing or upgrading Swarm, see Redis server.
API support changing for Swarm User Interface release (2020)
We have started adding a new set of v10 APIs to Swarm. These will provide a new endpoint and response pattern, and are designed for use with the new rich User Interface that is being introduced in 2020. Swarm will continue to support the v9 APIs for some time, see API versions.
API support changed for Swarm 2019.3
APIs older than v9 are being deprecated, support for them will be removed in a future release. See API versions.
Workflow feature support changed for Swarm 2019.2
The Swarm workflow feature is enabled by default. If you are upgrading from an earlier version you will need to update your triggers, see Upgrading Swarm.
PHP and Apache version support changed for Swarm version 2019.1
We have removed support for versions of PHP older than 7.0 in Swarm 2019.1. As a result of this change, support for Apache 2.2 has also been removed. This is part of our commitment to move away from using versions of platforms that have reached End-of-Life (EOL).
Ensure that you can install a supported version of PHP and Apache before upgrading to Swarm 2019.1. For information on versions of PHP and Apache supported by Swarm, see PHP and Apache web server.
P4PHP 2019.1 or later required for Swarm 2019.1 and later
The latest version of P4PHP is included in the Swarm package, OVA, and tarball installations.
