Lemma 3.1.0

What's new

Updates inside Lemma. Lemma › Check for Updates… shows what is new in a release, installs it and relaunches Lemma: no more downloading a disk image. If you agree (Lemma asks once, at its second launch), it also checks once a day, and it can download and install an update on its own when you quit (Settings › Updates). Updates are signed with the project's key, so Lemma installs only versions its maintainers published.

• The updating is done by Sparkle (MIT licence), listed in Help › Acknowledgements.
• Your choice of a daily check in Lemma 3.0 carries over.

Install or update

• From Lemma 3.0: choose Lemma › Check for Updates… (or open the notification), download Lemma-3.1.0.dmg below and drag Lemma into Applications, replacing the old one. This is the last time: from 3.1 on, Lemma installs its updates itself.
• New to Lemma: download Lemma-3.1.0.dmg, open it and drag Lemma into Applications (macOS 15 or later, Apple silicon or Intel). This build is not notarized by Apple, so the first time macOS says it cannot verify Lemma: click Done, open System Settings › Privacy & Security and click Open Anyway next to Lemma. You only do this once.
