It’s been a while since I did a proper package release announcement. Here are some packages that depend on the latest “level 9” kernel.

brickman (0.7.0)

Lots of changes in this release. The most obvious change is the increase in font size. We hope this makes it easier to read. The display on the PiStorms has higher DPI than the display on the EV3, so this font actually is still kind of small on the PiStorms.

In addition to supporting the most recent kernel and PiStorms, this release also ships with OpenRoberta support built-in (thanks to @ensonic). In order for this to work though, you will need a yet-to-be-released openrobertalab package. Stay tuned for more about that.

Another important change is that launching programs from the file browser in brickman will now be limited to the robot user. If you didn’t create a user named robot, you can find some instructions on how to rename your user and set the appropriate groups here (hope you can read it even though it is crossed out).

ev3devkit (0.3.0)

This is the toolkit that brickman is built on. Many of the brickman changes also required changes to ev3devkit. This means that ev3devKit works better on the Raspberry Pi now.

zram-init (3.5ev3dev1)

The latest kernel enables zram support. The zram-init package lets us take advantage of this for the swapfile. The 64MB of RAM on the EV3 is just not enough to run Debian so we don’t recommend running without swap on the EV3. However, having a swapfile on the SD card is A) very slow and B) will wear out your SD card faster. The swapfile provided by zram-init exists only in RAM, but is is compressed to free more RAM. The compression does use some CPU time, but it is actually still faster than writing to the SD card. (Note: The Raspberry Pi actually has enough RAM that we can run without a swapfile.)

This package will be included by default in the next image release. If you want to be an early adopter though, uninstall dphys-swapfile first, then install this package (but only after you have update to the most recent kernel).
