products | | Notes about Git support | All branches/tags are visible for all projects on the
same Git repository. Therefore, if you create some branches/tags for one
project, all other projects on the same Git repository will have the same
list.

About the unlock mode: Any item modified will be
kept locally, and will never be committed / pushed to the server until
the item is unlocked. Project items will be stored temporarily on the
stash system of Git if needed, so that they are not pushed until they
are unlocked. |

with Talend Studio | | Use of recursive Jobs | Avoid using recursive Jobs because this forces
recursive Jobs with the same dependencies build. In a normal case each Job
has its own Maven project, but with the use of recursive Jobs, all the Jobs
linked might be compiled inside the same project. This can easily cause some
compilation issues between the Jobs. |

and some earlier versions, you may have a problem opening the list of
database tables in MySQL components. If this happens, use MySQL database
driver 8.0.13 or a later version. |
