Here is a summary of the changes since the last release:

Release Notes for release-2024-07-03_23-01-hotfix-https-outcalls (16fabfd24617be66e08e00abc7ba3136bbd80010)

Changelog since git revision 5849c6daf2037349bd36dcb6e26ce61c2c6570d0

Bugfixes:

  • 16fabfd24 Networking: revert: reqwest https outcalls

A regression was observed in a commit 357ec1a, which switched the HTTP client library used for HTTPS outcalls in this week’s RC. This regression affects HTTPS outcalls to IPv4 targets, potentially causing more frequent timeouts compared to the previous version. These outcalls are only allowed on system subnets.

Subnet uzr34 was upgraded to this version, and the Exchange Rate Canister (XRC) experienced sporadic timeouts when making requests to IPv4 targets. Despite these issues, the Exchange Rate Canister is still able to retrieve enough data to keep exchange rates up to date. However, to be cautious, we propose reverting the offending commit and deploying a version without it on uzr34 with an expedited schedule. The same version will be deployed on w4rem. The remaining subnets will be upgraded to the RC version proposed and adopted earlier this week by the community, as they should not be affected by this change.

IC-OS Verification

To build and verify the IC-OS disk image, run:

# From https://github.com/dfinity/ic#verifying-releases
sudo apt-get install -y curl && curl --proto '=https' --tlsv1.2 -sSLO https://raw.githubusercontent.com/dfinity/ic/16fabfd24617be66e08e00abc7ba3136bbd80010/gitlab-ci/tools/repro-check.sh && chmod +x repro-check.sh && ./repro-check.sh -c 16fabfd24617be66e08e00abc7ba3136bbd80010

The two SHA256 sums printed above from a) the downloaded CDN image and b) the locally built image, must be identical, and must match the SHA256 from the payload of the NNS proposal.
