Plugin Settings

The following options are available for release system plugin:

Since version 1.6 Joomla has an Update System that allows you to update installed extensions automatically. And since January 10th 2017 supporting this system is almost mandatory for each extension.

jBackend Release System is a jBackend module that provides all features to implement a full Joomla Update Server and/or a generic Package Distribution System based on Joomla. It works with both jBackend and jBackend Community.

It can be used to distribute free packages, and paid packages as well. For paid packages the download restrictions are based on license keys, that are automatically generated and securely distributed to licensed users, authorized thorugh Joomla user's groups. Technical documentation is available here. An article that describes how it works can be found here.

Features

• Configurable packages distribution folder;
• Free and access restricted package distribution;
• Multiple package groups (releases in the same group share the license key);
• Multiple user groups can be enabled for each package group;
• Multiple package releases for each package group;
• Secret hash for each package group (increase security for generated license keys);
• Really lite (less than 700 lines of code).

jBackend Release System is released under GPL 2.0 license.

Premium Subscription is a lifetime subscription (it never expires) as supporter user. It is intended for professional developers who use our products for their business projects, and want to award our effort to create high quality software.

With this subscription it is possible to download any paid extension:

• ReDJ Enterprise
• Tag Meta Enterprise
• jBackend (and all additional modules included with jBackend subscription)
• jBackend Release System
• Auto Group

The Premium Subscription also includes some exclusive premium downloads, that are available only for premium users. The complete list is available here.

On May 4, 2017 we get a message from Joomla Vulnerable Extensions list (VEL) reporting the following security issue about Tag Meta Community 1.7.6:

http://seclists.org/fulldisclosure/2017/May/4

jBackend Community is the lite version of jBackend available for free, no subscription required. It provides all the basic features to integrate Joomla content with mobile apps, syndication networks, affiliate networks and any external system, and it is mainly intended to give a chance to test jBackend capabilities, to develop and test new modules, and to provide some basic REST API integration features to a Joomla site.

When the upgrade to the full jBackend version is required, it is possible to install the full jBackend package over the Community version. The two versions share the same data tables and settings, and the upgrade process will preserve the configuration and all existing data.

The Community version is completely free, but doesn't provide the full functionalities available for jBackend. Here's a comparison matrix between jBackend Community and jBackend:

Features	jBackend Community	jBackend
Extensible through plugins to increase API and support any Joomla extension	(2 plugins in the package)	(3 plugins in the package, 7+ included with the subscription)
Support for publishing of multiple endpoints, each with its specific settings
Three endpoint access type (free access, user authenticated only, API Key required)	(free only)
Tracing requests in the database for each endpoint
Selection of jBackend plugins to enable for each endpoint
API Key management interface	(not used)
Request log management interface
Each API Key can have a max daily requests limit and an expiration date	(not used)
Each API Key can be targeted on separate endpoints	(not used)
Access control is compliant with integrated ACL	(not used)
Support for REST compliant requests
JSON format for responses
Support for session ID	(only cookies)
Get the list of articles by tag id (content module)
Support for push notifications on iOS (APNs) and Android (GCM)
Custom payload for push notifications
Scheduled sending of push notifications
Push notifications can be create and scheduled via API call
Push notifications can be targeted on selected users, groups or devices
License	GPL 2.0	GPL 2.0
Price	Free	14 € (one year subscription)

The basic extension package includes the jBackend component, that provides the general infrastructure for endpoints, and plugins support system. Also the following plugins are already included in the basic package:

• User Module: provides support for Joomla users (e.g. login, logout, registration);
• Content Module: provides support for standard Joomla content (e.g. categories and articles);

Additional plugins are available only with a valid jBackend Subscription and can be downloaded from here and installed separately. More info about jBackend can be found here

jBackend Community is released under GPL 2.0 license.

Just received this email and we are really proud that our work is still really appreciated.
