TYPO3 Core

I just noticed that the behavior of the keepItems setting in page TSconfig changed from TYPO3 6.2 to TYPO3 7.x (tested in 7.5).

Example 1:

TCEFORM.tt_content {
  header_layout {
    keepItems =
    addItems {
      1 = Ebene 1 (nur einmal auf der Seite verwenden)
      0 = Ebene 2
      12 = Ebene 2 (Akzentfarbe)
      3 = Ebene 3
      13 = Ebene 3 (Akzentfarbe)
      4 = Ebene 4
      14 = Ebene 4 (Akzentfarbe)
      100 = Verborgen
    }
  }
}

• TYPO3 6.2: Removes all existing items from the select and adds all new ones
• TYPO3 7.5: Adds all new ones and keeps all existing items

Example 2:

TCEFORM.tt_content {
  header_layout {
    keepItems = 1
    addItems {
      1 = Ebene 1 (nur einmal auf der Seite verwenden)
      0 = Ebene 2
      12 = Ebene 2 (Akzentfarbe)
      3 = Ebene 3
      13 = Ebene 3 (Akzentfarbe)
      4 = Ebene 4
      14 = Ebene 4 (Akzentfarbe)
      100 = Verborgen
    }
  }
}

• TYPO3 6.2: Removes all existing items except for 1 from the select and adds all new ones
• TYPO3 7.5: Adds all new ones and then removes both existing and new ones except for both 1s

Example 3:

TCEFORM.tt_content {
  header_layout {
    removeItems = 0,1,2,3,4,5,6,100
    addItems {
      1 = Ebene 1 (nur einmal auf der Seite verwenden)
      0 = Ebene 2
      12 = Ebene 2 (Akzentfarbe)
      3 = Ebene 3
      13 = Ebene 3 (Akzentfarbe)
      4 = Ebene 4
      14 = Ebene 4 (Akzentfarbe)
      100 = Verborgen
    }
  }
}

• TYPO3 6.2: Adds all new ones and then removes both existing and new ones except for 12, 13 and 14
• TYPO3 7.5: the same

In my opinion the way TYPO3 6.2 interpreted the keepItems setting was more flexible because it allowed me to rename and reorder items without messing with the css_styled_content TypoScript.
