It appears in the latest version of the Manual of Indulgences, which I bought from Amazon for my Kindle and consult daily. (2006 translation by USCCB of the 1999 current version, available from Amazon
here.)
First of all, thank you for the link, which gives the 1999 edition of the Enchiridion. It is the fourth edition of the 1968 edition. Like the 1968 edition, the grant at the point of death in the 1999 edition does not appear in the
Norms section (Norms 18, p. 22) of the Enchiridion. However, it appears in the
Grants section at the location you indicated (Sect. 12, p.47). So, I went back to the old 1968 Edition and started looking for the same paragraph in the Grants portion. And here I found it there as well. If you still have the link I provided earlier, you will find it under “Other Grants of Indulgences”, #28, pp. 27-28. I thought earlier that they removed the paragraph altogether since it was no longer in the Norms section. (It was in the Norms section of the 1967 Apostolic Constitution by Pope Paul VI). I did not know that they merely moved it to the Grants section. So, now I agree. The plenary indulgence at the point of death is still current. You win.

And thanks again for pointing that out.
I’m thinking now, that it makes it much easier for Catholics to bypass purgatory, right? Just have the habit of praying everyday, and continue keeping yourself in the state of grace. On the other hand, it may not be that easy because Norm 20 (p. 22) in the 1999 Edition still has the requirement to be free of all attachment to sin, even venial sin, in addition to the three conditions (sacramental confession, Holy Communion, and praying for the intentions of the Holy Father). That requirement is still in effect. Now, the plenary indulgence at the point of death given in Section 12 (p.47) does not require these three conditions, but is granted to the faithful “who are duly disposed.” I suppose that means you are duly disposed when you are free of all attachment to sin, including venial sin. Many people find that requirement hard to satisfy. Any thoughts?
