# libtomcrypt 1.18.0 RC5

Hello everybody,

okay, now it should really be the last Release Candidate of libtomcrypt 1.18, Number 5.

Here’s the list with the biggest changes since RC4.

• The ABI version/SONAME had to be bumped to 1:0 after Dan Fandrich of Mageia Linux pointed out that the ABI is incompatible to 1.17. But this release should still be a more or less drop-in update from 1.17 (but it requires re-compiling and re-linking).
• Rob Swindell discovered an issue when rsa_import()‘ing keys where we would use a lot too much memory. This lead to a bigger PR which also removed the MIN_RSA_SIZE and MAX_RSA_SIZE macros…
• makefile.shared can now also be used on cygwin.

Again, if you’re having issues with the RC5 you know where to report: [ML] or [GitHub].

Cheers,

Karel & Steffen
