Security

This release has been built with updated Go runtime 1.26.10 to address CVE-2026-111943 by rejecting certificate chains that include eight revoked eMudhra intermediate certificates.
Image pulls and pushes fail TLS certificate verification if a registry's certificate chain relies on one of the affected TLS intermediates.
Affected registries need a replacement certificate chain that does not use these intermediates.

The blocked intermediates are:

  • Domain-validated TLS：EM DV TLS CA - G3B and EM DV TLS CA - G3C
  • Organization-validated TLS：EM OV TLS CA - G3B and EM OV TLS CA - G3C
  • Extended-validation TLS：EM EV TLS CA - G3B and EM EV TLS CA - G3C
  • Code signing：EM OV CS CA - G3B and EM OV CS CA - G3C

The G3B intermediates belong to eMudhra BV, and the G3C intermediates belong to eMudhra Inc.
The keys for these intermediates were compromised.

There are no functional changes in Buildx itself compared to the previous release.

Arduino Builder

Arduino Builder 1.0.13

Arduino Builder is a standalone utility for viewing, compiling and uploading Arduino sketch files and compiled ELF or HEX files to Arduino boards with the Arduino serial programming interface, Arduino ISP or USBasp, without the need for the Arduino IDE. The app has a standard user interface with drop down menus to choose the data you need. The functions of the utility can be undertaken in 3 steps. When compiling is required, for uploading sketch file, Arduino Builder scans the sketch for referenced libraries and then builds the necessary libraries automatically. The distribution package contains Arduino 1.0.4 core and library files, AVR GCC compiler toolchain and AVRDUDE. Please be aware that as only the standard Arduino libraries are shipped with the utility, if you want to build with custom libraries, then you will need to place the library source code files with the identical directory name into /arduino/libraries directory.
