Hi Dmitry,
This is because the linked page is not published in the blog. The entry
can be found in the changelog[0]. The reason why posts like this
aren't in the blog can be seen in the explanation[1]. Basically, the
blog is meant for small updates, an online journal, content that doesn't
fit this category for some reason goes elsewhere.
Thanks for your question. You have the honor of being the first person
to ask something on this mailing list :-)
