Better routing, probe fixes, plugin updates in Freenet/Hyphanet 0.7.5 build 1507

summary

Hyphanet release 0.7.5 build 1507 introduces critical updates to privacy, system performance, and development infrastructure. The project is officially dropping support for Java 8 to move to Java 17, streamlining the build process and enabling modern language features. Additionally, the update fixes a significant anonymization bug in probe requests and optimizes node startup times for a smoother user experience.

key points

1. The transition to Java 17 is necessary because Debian no longer supports Java 8, making the build system brittle and difficult to maintain. This change allows developers to use modern Java features like records and pattern matching while requiring users to update their Java installation to continue receiving updates.
2. A security vulnerability regarding the lack of location randomization in probe requests was identified and fixed by adding linear random noise to the location data. This ensures that the anonymization of these requests is properly maintained, protecting user privacy from potential observers.
3. Node startup is now faster due to reduced wait times for addresses without DNS entries and improved handling of DNS request throttling. Other quality-of-life improvements include better UTF-8 support for plain text files and a more robust implementation of HTTP 1.1 pipelining.
