Here's a service announcement because Ivan-sama just fucking sucks at communicating new releases outside of his I2P-only IRC channel.
i2pd 2.45.0 is now available, and fixed quite a lot of problems in 2.44, and even became even more superior to the regular Jewva version of I2P than it already was.
For OpenBSD users, it's advised to get the ports package from here: https://gitler.moe/koishi/openbsd-ports
For everybody else: https://github.com/PurpleI2P/i2pd/releases/tag/2.45.0

Users of a DPKG-based or RPM-based distro can install from .deb or .rpm file.

Users of Arch-based, Install Gentoo-based, Slackware-based, Void, or any other distro's, install Boost and OpenSSL (if not done already), then wget the Tarball (Source code (tar.gz)), do tar zxfv 2.45.0.tar.gz, make, and make install.
Void and Arch-based distro users can also wait a few days or poke their distro maintainers to let them know that the new version is out now.

For FreeBSD users, you'll probably need to wait a bit longer, because FreeBSD's make command doesn't understand if/else commands in the Makefile for some stupid reason, and gmake doesn't support the "install" command, making it uninstallable on FreeBSD for the time being.
