  QCD under extreme conditions has been studied for a long time, and the chiral
limit has been a grey area mostly. In this write-up of my talk, I review some
of the recent developments made by the community to unveil various features of
QCD towards the chiral limit, which includes calculation of the chiral critical
temperature and determination of the order of chiral phase transition for
various numbers of flavors. Acknowledging the importance of the studies
regarding the effective restoration of $U_A(1)$, I try to give a comprehensive
overview about the various studies done in the last few years in a comparative
manner to realize the current status of the community in this regard. I also
discuss very recent efforts about the relevance of various energy-like
observables w.r.t. the chiral phase transition.
