2025-10: GNU Taler v1.1 released

We are happy to announce the release of GNU Taler v1.1.

This release focuses on making it easier to setup and configure merchant backends, specifically enabling self-provisioning. At my.taler-ops.ch merchants accepting payments via of Taler Operations AG can now configure their own merchant backend without having to operate their own server.
We encourage business owners and developers in Switzerland to set to work on accepting GNU Taler. We have updated our tutorials, with new video tutorials available with audio and subtitles in Czech, English, French, German, Greek, Japanese, Portuguese, Russian, Spanish, and Slovak! We encourage you to use the Integrator Community Hub to receive community support.

About GNU Taler

GNU Taler is a Free Software payment system that preserves the privacy of payers while ensuring that income is visible to authorities. Regulated payment service providers use the Taler protocol to issue digital cash denominated in a fiat currency. The digital cash tokens are stored in electronic wallets under the full control of its respective owner. The payment service provider has an escrow bank account holding the equivalent of all digital cash in circulation.
Merchants redeeming digital cash receive aggregate transactions over the respective amount into their regular bank account. Digital cash transactions happen basically instantly, and must be performed online to prevent double-spending.
Support exists for offline points-of-sales to accept transactions where only the customer is online. GNU Taler is scalable and technologically suitable for regional currencies (such as eNetzbon), commercial deployments (such as Taler Operations AG) or central bank digital currencies (CBDC).
