The Liberty-for-Java Buildpack v3.523 now includes Liberty runtime 21.0.0.1 as the alternate runtime.

The Liberty-for-Java Buildpack v3.53 adds Liberty runtime 21.0.0.1 as the alternate runtime and keeps 20.0.0.12 as the default runtime. The AdoptOpenJDK Open J9 alternate JRE 11.0.9_11_openj9-0.23.0 and IBM JRE Version (8 SR 6 FP20) remains the same.

This buildpack contains two production versions of Liberty — a default version that remains constant for approximately three months and the latest version, as an alternate. 

An existing application will not be affected by the new buildpack until you redeploy or restage it. After redeployment, existing applications should continue to run “as is” without any additional changes. New applications will automatically use the new buildpack.

Microcontrollers vs. microprocessors: What’s the difference?

6 min read - Microcontroller units (MCUs) and microprocessor units (MPUs) are two kinds of integrated circuits that, while similar in certain ways, are very different in many others. Replacing antiquated multi-component central processing units (CPUs) with separate logic units, these single-chip processors are both extremely valuable in the continued development of computing technology. However, microcontrollers and microprocessors differ significantly in component structure, chip architecture, performance capabilities and application. The key difference between these two units is that microcontrollers combine all the necessary elements…
