0.8.7 Release - Blog

0.8.7 Release - Blog

  • Posted: 2011-06-27
  • Author: I2P devs

I2P release 0.8.7 contains several upgrades to long-neglected components, including the Naming Services, graphing, the native CPU ID and BigInteger libraries, crypto implementations, and the wrapper.

Thanks to new contributor KillYourTV who was instrumental in implementing and testing these upgrades, with additional support from sponge and hottuna.

CPU ID enhancements are by hottuna, generously funded by http://relakks.com/ and http://ipredator.se/ - thanks to Peter Sunde and Jan-Erik Fiske for their support.

Also, for the first time, we now have an official I2P Personal Package Archive (PPA) on launchpad.net. For those of you using Ubuntu, this offers an easy way to install I2P and keep the various components up-to-date. The I2P package offers the option of installing as a service, or it may be started on-demand as usual. This PPA is currently maintained by KillYourTV with support by other members of the development team. The Ubuntu/Debian installation instructions are on our website.

For those updating over the network, this update is about 4 times the usual size, due to the inclusion of the jbigi updates. Please be patient while downloading the update over the network.

Please help grow the network. Get involved, spread the word, and donate! If you find a bug, please enter a report on trac. We are still looking for help on new and existing translations. Please volunteer on IRC #i2p-dev.

Files are available on the download page.

Big changes (upgrades and new installs)

* NamingService upgrades to support new features, including a hosts.txt database that will be enabled in release 0.8.8
* New form in the HTTP proxy to save new hosts with address helpers to hosts.txt
* Speedups for SHA-256 and SHA-1 hash computation, most noticeable on GNU JVMs.
* Upgrade to JRobin 1.5.9 for better-looking performance graphs
* Persistent graph data across restarts

* JCpuid / JBigI upgraded to libgmp 4.3.2 / 5.0.2 and the libraries are PIC compliant, and contain improved support 64-bit on most architectures. JBigI is a native library which significantly speeds up cryptography operations.

- For those on grsec / ASLR kernels where I2P was crashing due to non-PIC libraries, I2P should now work.
- For those on x86 64-bit systems, crypto will be faster (typical result is a 25% improvement), which you may notice in lower CPU usage
- For those on ARM or x86 OS X systems, crypto should be much faster, as we did not have jbigi support for these systems before.
- For those on most other 32-bit Linux, FreeBSD, or Windows systems, there should be no noticeable change in performance.

Big changes (new installs only)

* The Wrapper was updated to version 3.5.9 and the libraries are now PIC compliant, and support 64-bit on most architectures. For those who did not have a working wrapper before (those on grsec / ASLR kernels, or freebsd, ARM ,or x86 OS X) manual upgrade of your wrapper libraries is possible. Instructions at http://www.i2p2.de/manualwrapper . For FreeBSD users see http://www.i2p2.de/faq#compat6x . Alternative: delete existing installation and install a new. Second alternative for Ubuntu: delete existing install and use PPA. For those who have a working wrapper now, a manual upgrade is NOT recommended.

Packaging news:

* Debian / Ubuntu - Major upgrade of the Debian packaging scripts to comply with packaging rules.
* PPA - As described above.

Bug Fixes

* The update includes local Jetty patches that were inadvertently omitted from the 0.8.3 and 0.8.5 install packages,
* A workaround for noncompliant UPnP devices
* Fix bug preventing Robert from initiating a connection to i2psnark

Other

* More adjustments for recent network growth, including increasing the number of floodfills and lowering the number of router infos stored locally.
* Exchange version numbers across I2CP, to allow future changes to be backward-compatible
* Swedish translation, thanks 123hund123, hottuna and digitalmannen
* Partial Finnish, Italian, Polish, and Vietnamese translations, thanks to the Transifex translation teams
* Arabic translation updates, thanks hamada
* Russian translation updates, thanks hiddenz
* GeoIP update (new installs only)
