Abstract
Since the incident nuclei in heavy-ion collisions do not carry strangeness, the global net strangeness of the detected hadrons has to vanish. We investigate the impact of strangeness neutrality on the phase structure and thermodynamics of QCD at finite baryon and strangeness chemical potential. To this end, we study the low-energy sector of QCD within a Polyakov loop enhanced quark-meson effective theory with 2+1 dynamical quark flavors. Non-perturbative quantum, thermal, and density fluctuations are taken into account with the functional renormalization group. We show that the impact of strangeness neutrality on thermodynamic quantities such as the equation of state is sizable.

Author comments upon resubmission
List of changes
(1) Edited Eqs. (13) and (14) to make the dependence on \bar{A} explicit.
(2) Added/modified Eqs. (16) and (17) on page 4.
(3) Removed the wave function renormalization / anomalous dimension from the discussion in and after Eq. (38).
(4) Emphasized the smallness of the effect of strangeness neutrality on the pseudocritical temperature at the beginning of Sec. IV.E and streamlined the discussion on the top left of page 15.
(5) Added the chiral and deconfinement crossover lines in Fig. 8.
(6) Corrected an embarrassing typo in App. B, left column on page 19.
(7) Removed some word duplications that we were able to find.
(8) Added our source to the caption of Tab. II on page 17, and pointed it out again after Eq. (A1)
(9) Mentioned potential errors from the initial conditions in Sec. IV.A., in the paragraph after Eq. (49).
(10) Clarified the definition of the speed of sound in and right after Eq. (54).

Report
The authors of the present manuscript have addressed almost all of my concerns in a satisfactory manner.
However, though the authors agree with my second point concerning the lengthy setup in Sec II and III, they have only made marginal changes. This is regrettable since the lengthy discussions obscure the core of this work. I do not think it is always a matter of taste as to whether one should make effort to improve accessibility, readability and, subsequently, impact.
Nevertheless, to avoid any further delay this work should be published now.
