Dirshu
The Dirshu Mishnah Berurah contains elements that will be craved by talmidei chachamim and laymen alike:
1) Halachah l'ma'aseh rulings on new, modern-day shailos
2) Previously unpublished insights noted on the pages of the personal Mishnah Berurahs of gedolei Yisrael
3) Additions and cross-references similar to "Musaf Rashi" found in many Gemaras
4) Piskei Chazon Ish
5) Explanations to the Mishnah Berurah where unclear
