EDA CAD files for v1.0.6 were published to the [l5-schematic repo](https://source.puri.sm/Librem5/l5-schematic).
* Versions 1.0.3.1 and 1.0.6.1 have made minor changes to improve GNSS reception. Purism hardware engineer Eric Kuzmenko noted that "antenna feedline component values were not finalized until after the schematic was published" and provided the changes in this forum [post](https://forums.puri.sm/t/librem-5-gps-location-tracking/14153/211) and these [instructions](https://source.puri.sm/Librem5/OS-issues/uploads/ffece0815fd2d8a64574a18796e662fc/GNSS_sensitivity_ECO_for_customers.pdf) to change the components on the main board to improve GNSS reception.
