The following changes have been implemented for https://docs.magnolia-cms.com/product-docs/Templating/Dialog-definition/Field-definition/List-of-fields/Link-field.html:

• buttonSelectNewLabel defaults to translated fields.button.select.new key.
• buttonSelectOtherLabel is deprecated.
• emptySelectionAllowed defaults to false.
• filteringMode defaults to CONTAINS.
• New showOptions = false.
• showOptions and textInputAllowed have to be set to true for filtering to work.
   To enable filtering, you have to set both showOptions and textInputAllowed to true.
• pageLength has nothing to do with filtering.
  pageLength
  optional, default is 0
  To enable paging in the field pop-up, the value must be an integer greater than 0. A value of 0 disables paging and makes all items visible.
• showOptions has to be set to true for options to appear in a combobox. The warning about possible performance issues should be moved to the showOptions property.
   Enabling and using showOptions with a data source that contains large data sets may lead to performance issues.
