Indeed, it has been a busy year for Magento as I said it would be.
Magento launched its new release on 14th January 2020, which was Magento version 2.3.4. Magento quarterly releases updates to the security and functional patches. Magento 2.3.5. was the latest release until it launched a beta version Magento 2.4.0. on 1 June 2020.
The catalog search engine will be removed from Magento 2.4.0. and Elasticsearch 6.x or 7.x will be a required component.
The reason for removal of MySQL search engine is that Elasticsearch provides superior search capabilities as well as catalog performance optimizations.
An Elasticsearch host that is setup and configured, is required prior to installing version of Magento 2.4.0. Magento’s will attempt to connect to a server at localhost:9200.
During installation the Elasticsearch connection will be checked, and installation will fail if Magento is unable to connect to an Elasticsearch host. If this occurs, make sure to check if Elasticsearch is up and running, and check that you have used the correct connection details.
If your configuration does not match the defaults, these settings can be configured by using arguments passed to setup:install, in much the same way the database connection is configured.
Affected products and versions:
Magento Commerce v2.4.0 and Magento Open Source v2.4.0
At this time, participation in the Magento Beta Program is required for access to the test the new search.
