In the Gospel of Mark, I added the diamonded variant readings indicated in the Tyndale House Greek New Testament (the diamond meaning another variant of equal weight as the one printed in the main text), plus a half dozen new TC footnotes, and a few updates from the Editio Critica Major (ECM). So this is essentially a 3rd edition of Mark, which you can download here, or purchase a Mark printed edition here.

I recently purchased the ECM of Revelation, so am in the process of updating the Apocalypse of John textual criticism footnotes, including also adding the diamonded readings from the Tyndale House GNT.

I also purchased the ECM of the Acts of the Apostles, and am still creating the TC footnotes for Acts.
