The download can be obtained through Fix Central, a link to which will be found here. One change is that you now have to log in under your IBM account to download from Fix Central. The downloads for both 32 and 64 bit are around 650-700 Meg.
The "release notes", if one may bestow a "page with a random set of links" with such a grand title, will be found here. Why there is no .pdf with all relevant information contained in it (you know, like release notes used to be) is an unknown, but the absence of such could explain why the page currently has an average rating of 1 star from 2 users. After all, this whole "being able to read a topic from start to end in a logical sequence" is sooooo last century. Far better to have people jumping all over the place looking for nuggets of information.

In a separate release, there are also interim fixes available for 9.5.2, 9.5.1 and 9.4.1 which "address a potential issue with the TM1 Admin Server, which may result in a "Buffer Overflow" attack against the server running this software".
This sticky post will expire in 30 days.
Edit: I removed the link to the Download Page from the text above. The reason is that whoever created the link from the release notice to the download page pointed it to the FP1 download page rather than the FP2 one. Not that either are particularly useful so I changed the link to point straight to the Fix Central page.
The real FP2 Download page does also mention that:
Unix and Linux based installs are not available for download but can be requested through Customer Support.
