Remember when Log4J happened and everyone said "well let's just move away from Java"? Yeah, me neither. And that was just as big a deal.

Sysadmins, upgrade your servers. This is an easy process. If it's not, then the problem isn't PHP, it's your process. The same would be true for a JVM bug, Windows bug, Go bug...

If your org couldn't upgrade quickly and easily, this is a wake up call to review your release process.

@frankdelporte explains how Sheetmusic4J 0.0.5 adds LilyPond import and export. A .ly file can now be loaded and rendered natively in JavaFX without running LilyPond, and any score can be saved as LilyPond to get a high-quality PDF.

The release also brings engraving improvements like nested tuplets and octave clefs.

Your security policy doesn't allow sending secrets outside your build environment? Starting with v1.10.0, the setup-testlens GitHub Action can authenticate via OIDC instead of the job's GITHUB_TOKEN.

✅ Grant `id-token: write`, set `use-oidc: true`, done.

Asking your manager for conference budget can be harder than giving a talk. So we wrote the letter for you.

Our #JCON2027 convince-your-boss letter starts with "Dear {{JavaLovingAndTotallyAwesomeBoss3000}}" and gets serious from there: the talks, the Mentorship Hub, 1:1 meetings with speakers, a certificate of attendance.

You fill in your name, your project and the prices. Right now, blind tickets are 30% off.

New on Foojay: Lottie4J 1.2.7 focuses fully on performance, with no new features. @frankdelporte explains how images are now decoded once and track mattes reuse canvases and buffers. In the profiling run, GC pauses dropped from 531 to 177.

Note: use 1.2.8 instead, as it fixes a regression with track mattes of different sizes.
