Applying a Talend Data Catalog patch
A patch is a software update that contains new features and bug fixes.
You cannot use a cumulative patch for a major version upgrade, you must start from a clean installation of the new major version.
You cannot reverse or unzip an older cumulative patch, you must restart from a clean installation of the original version.
As the patches are cumulative, Talend recommends you to apply the latest patches available to keep your installation including all harvesting servers up-to-date.
Two types of patch file are available as .zip files only. You install them in the same way and if both are to be applied at the same time, then apply the one with the older timestamp first, followed by the newer one.- x.y. corresponds to package version number (Major.Minor)
- YYYYMMDD corresponds to the package timestamp
| File name | Description | Note |

The patch is delivered as a .zip file and can include all the .dll files required for its installation on a Windows server. On Linux and Unix, you can unzip the file, delete any .dll and .exe files in the bin sub-folder, and re-compress the folder structure in an appropriate archive file format, such as .tbz2.
You can also have another patch file, named ModelBridgeList-yyyymmdd.xml, to be downloaded and applied to your installation. This file can contain some new or updated bridges.
