2026-10 · Colors in the dashboard

[Per-code colors now in the dashboard — checked before you save](/fr/changelog/2026-10-qr-farben-dashboard-en/)

The Colors card on the detail page: hex values, transparent background, a live verdict in four levels, a preview from the real image route and a reset to black on white.

2026-10 · Colors in PDF and EPS

[Colored QR codes in PDF and EPS too — as print colors](/fr/changelog/2026-10-qr-druckfarben-en/)

fg, bg and stored colors now show in qr.pdf and qr.eps as well. Black and grey as grayscale on one plate, other colors as CMYK in whole percent, background like the SVG.

2026-09 · Deletion

[Deleted accounts stop redirecting, concurrent changes report 409](/fr/changelog/2026-09-deletion-and-concurrent-changes-en/)

After an account is deleted, a static code stops redirecting on the next call of its short link instead of up to 24 hours later. Two simultaneous deletions send only one webhook, two simultaneous logo changes report 409.

2026-09 · Expiry

[A changed expiry applies within about a minute](/fr/changelog/2026-09-expiry-within-a-minute-en/)

A PATCH to expires_at now clears the code's redirect cache, and the change applies within about a minute. Before, a code could keep redirecting or keep reporting itself expired according to the old expiry for up to 24 hours.

2026-09 · Colors on the code

[Store colors on a QR code — with a contrast check](/fr/changelog/2026-09-qr-colors-stored-en/)

PATCH /v1/codes/:id accepts appearance: foreground and background color stay on the code, SVG and PNG draw them without parameters, PDF and EPS follow. Below 1.5:1 contrast the API says no.

2026-09 · Colors and error correction

[Colored QR codes and selectable error correction — via the API](/fr/changelog/2026-09-qr-colors-en/)

fg, bg and ecc on qr.svg, qr.png, qr.pdf and qr.eps: colored codes, transparent PNGs and more robust error correction for print. Invalid values are ignored, never an error.

2026-09 · Logo in PDF and EPS

[PDF and EPS now show the logo just like SVG and PNG](/fr/changelog/2026-09-logo-pdf-eps-en/)

Vector print templates get the logo too: PDF and EPS now embed the same pixels as SVG and PNG, with the same error correction H and the same 5-minute cache.

2026-09 · Logo in the QR code

[A logo in the middle of the code — without it stopping scanning](/fr/changelog/2026-09-code-logo-en/)

A QR code with your own logo in the middle, no separate image editing needed and without the code breaking. Upload it in the dashboard or via API, embedded straight into SVG and PNG.

2026-08 · Named API operations

[Every API operation now has a stable name — and qr3.app says what it is for](/fr/changelog/2026-08-named-api-operations-en/)

Generators no longer invent method names, they read them from the specification. And anyone letting an assistant use qr3.app now gets guidance instead of an inventory.

2026-08 · Machine-readable API

[qr3.app now serves Markdown — and describes its API machine-readably](/fr/changelog/2026-08-machine-readable-api-en/)

Read the homepage or the blog with a program and you now get Markdown instead of HTML — and the API description sits at a fixed, standardised address.

2026-08 · 24 languages on scan

[The pages your customers see now speak 24 languages](/fr/changelog/2026-08-scanner-pages-24-languages-en/)

Whoever scans your code sees two qr3-hosted pages. Both were hard-wired to German, no matter where the scan came from. That is fixed.

2026-08 · Security headers

[Redirect page hardened — target URLs are now escaped](/fr/changelog/2026-08-redirect-security-headers-en/)

The interstitial page shown before a redirect used to print the target URL unescaped. That is fixed — and every redirect response now carries security headers.

2026-06 · Scan quota

[Stay ahead of your scan quota](/fr/changelog/2026-06-scan-quota-warnings-en/)
