The CALIFA survey: Status Report
  We present here a brief summary of the status of the on-going CALIFA survey
with an em- phasis on the results that have been recently published. In
particular, we make a summary of the most relevant results found regarding the
properties of Hii regions discovered using this survey, and the evidence
uncovered for an inside-out growth of galaxies. In particular, we present an
updated version of our results on the exploration of the Mass-Metallicity
relation using spatial resolved information, with almost the double number of
objects analysed, and an enlarged number of galaxies in the lower-mass range.
We confirm our previous results that shows a lack of secondary relation with
the SFR.
