Release notes 

0.9.4 includes a fix for a network capacity bug, introduced in 0.9.2, that was reducing network performance and reliability. It also includes major changes in the in-network update system, and adds the capability to update via in-network torrents.

We fixed several bugs in the i2psnark DHT implementation that was introduced last release. For those of you using console or http proxy passwords, we converted to the more-secure digest method and improved the security for console forms.

For those of you already running development builds, your router should automatically update to 0.9.4-0 using the new in-network torrent facility. For those running 0.9.3-0, you will update normally using in-network HTTP, and we will have more information for you when we release 0.9.5.


Major Changes

- Big rework of the update system; Preliminary support for updates via i2psnark
- Add per-destination outbound priorities

Bug Fixes

- Fix major bug that reduced SSU connection limits which reduced tunnel build success rates
- Fix bug with external I2CP that prevented some external apps from working
- Fixed several bugs in i2psnark DHT
- Fixed bug in i2psnark PEX that inflated peer counts
- Handle dropped I2CP messages better
- Reduce overhead of I2CP messages
- Enforce max size in transport outbound message queues
- Fixes for Windows eepget.bat (new installs and PPA only)
- Fix a bug that would drop messages of exactly 512 bytes in SSU


- More performance improvements, memory reduction, and object churn reduction
- Better detection of network disconnections
- Further improvements in the SSU transport
- Add console password form
- Convert http proxy and console from basic to digest authentication for added security
- Improved verification of console form submissions, using jsp sessions. Cookies may now be required on forms, except when the console password is enabled
- Initial work on new interfaces to manage applications started via clients.config
- Increase minimum peer port to 1024
- Increase granularity of bandwidth limiter for smoother transmissions
- Translation updates: Chinese, French, German, Italian, Polish, Portuguese, Swedish, and Ukrainian
- Update GeoIP data (new installs and PPA only)
- Update wrapper to 3.5.16 (new installs and PPA only)
- New ARMv6 wrapper for Raspberry Pi
