  Ongoing progress in understanding and evaluating charge symmetry breaking in
$\Lambda$ hypernuclei is discussed in connection to recent measurements of the
$_{\Lambda}^{4}{\rm H}(0^+_{\rm g.s.})$ binding energy at MAMI [A1
Collaboration: PRL 114 (2015) 232501] and of the $_{\Lambda}^{4}{\rm
He}(1^+_{\rm exc})$ excitation energy at J-PARC [E13 Collaboration: PRL 115
(2015) 222501].
