If you go to [Parltrack’s dumps page](https://parltrack.org/dumps), you will find a `ep_meps.json.lz` file available to download.

howdy, just in case you still haven't updated your acquisition pipeline, a few months ago parltrack switched from lzip to zstd compression. the latter is slightly worse in compression, but much more widely supported on lock-in systems like apple and microsoft restrictionwares.

Thanks :) Yeah, I've already noticed that a few days ago, and there's already #305 to support importing these directly, but I'd probably have missed updating the docs as well.

Closing this and tracking in #305, again thanks for the heads-up.
