Magento 1.x Security Patch Notice
For Magento Open Source 1.5 to 1.9, Magento is providing software security patches through June 2020 to ensure those sites remain secure and compliant. Visit our information page for more details about our software maintenance policy and other considerations for your business.
Using a Staging Environment
A staging environment is just like any other Magento installation, but is not accessible to the public. You can use a version control tool to keep files synchronized between the staging environment and the live store. We highly recommend that you use a staging environment to test extensions and before updating your live store to a new version of Magento Open Source.
