I2P is now a proposed site on Stack Exchange! Please commit to using it so the beta phase can begin.

Update details

0.9.26 contains a major upgrade to our native crypto library, a new addressbook subscription protocol with signatures, and major improvements to the Debian/Ubuntu packaging.

For crypto, we have upgraded to GMP 6.0.0, and added support for newer processors, which will speed up crypto operations considerably. Also, we are now using constant-time GMP functions to prevent side-channel attacks. For caution, the GMP changes are enabled for new installs and Debian/Ubuntu builds only; we will include them for in-net updates in the 0.9.27 release.

For Debian/Ubuntu builds, we have added dependencies on several packages, including Jetty 8 and geoip, and removed the equivalent bundled code.

There's a collection of bug fixes also, including a fix for a timer bug that caused instability and performance degradations over time.

Come sempre consigliamo ad ogni utente di aggiornare il proprio sistema a questa versione. Il modo migliore per essere anonimi ed aiutare gli altri ad esserlo è eseguire un software aggiornato.
