The other batch of stickers arrived. These are much more vibrant compared to the first batch and do not have the white border. Really happy how these turned out. There is ~100 of each style for #atmosphereconf

First batch of stickers for #atmosphereconf arrived. Getting them from 2 different suppliers with slightly different styles so there will be plenty to hand out.

Other changes are the Hold now supports did:plc instead of just did:web. This will allow easier migrations across domains. The admin panel also has a new relay page to check if the relays have the latest data. this is inspired by debug.hose.cam but contains the firehose.network relays as well.

Big changes happening. Vulnerability scanning has (mostly) landed. you can take a look at the example here atcr.io/r/evan.jarre... It will be processing images in the background and eventually on push. This is built using Syft and Grype. and records are stored in the holds embedded pds

Spent the weekend micro-optimizing everything on the atcr.io page rendering and navigation should be much faster, and avatars are now not trying to load the full native resolution.

Spent some time on the UI. The homepage got more of a redesign. Also added the ability for data export and deletions, so data that is stored by ATCR, but not in your PDS can be viewed/removed at any time.

In addition to working on quotas, An admin dashboard was added to Holds to manage access, quotas, view metrics etc. This is all running off public data from PDS, but gives an easy way to view/edit.

New in atcr.io you can edit your repo's avatar from the UI. This requires updated oauth scopes, so you will need to log out and back in. Note this also applies using labels/annotations when building: --label io.atcr.io="https://my.cool/image.png"
