  The J\"ulich-Bonn group aims at an extensive study of the baryon-baryon
($BB$) interaction involving strange baryons ($\Lambda$, $\Sigma$, $\Xi$)
within SU(3) chiral effective field theory. An overview of achievements and new
developments over the past few years is provided. The topics covered are: 1)
Derivation of the leading charge-symmetry breaking (CSB) interaction for the
$\Lambda N$ system and its application in a study of CSB effects in $A$=$4$
$\Lambda$-hypernuclei. 2) Updated results for the $\Xi N$ interaction at NLO
and predictions for $\Xi^- p$ correlation functions. 3) Extension of the
$\Lambda N$-$\Sigma N$ interaction to next-to-next-to-leading order.
