# libtomcrypt 1.18.0 RC2

Hello everybody,

we just created the second Release Candidate of libtomcrypt 1.18.

Well, the plan to not change the API didn’t hold, but it’s only minor and now more in-line with what we already added.

Here’s the list with the biggest changes since RC1, the changes that are left out were pure cosmetics.

• fixed docs generation with TeX Live 2017
• fixed the default make-target of makefile and makefile.shared (oops)
• fixed some scenarios where the build could fail because of wrongly ordered includes
• added an uninstall make-target
• improved the GCM API by some potential use-cases
• updated the API of dh_set_key() and dsa_set_key()

Again, if you’re having issues with the RC2 you know where to report: [ML] or [GitHub].

I received the question which versions of libtommath and/or tomsfastmath are at least required to be able to build the RC with MPI providers:

• libtommath - v0.42.0
• tomsfastmath (static library) - v0.13.0
• tomsfastmath (shared library) - current develop [tfm/develop] or newer

Cheers,

Karel & Steffen
