[qos.ch-announce] Release of logback versions 1.3.9 and 1.4.9

[QOS.ch annoucements]

Hello all,

I am happy to announce the simultaneous release of logback
versions 1.3.9 and 1.4.9. Both versions require slf4j-api version
2.0.x or later.

This is the first logback release with GraalVM in mind.

In addition to bug fixes, logback now ships with
SerializedModelConfigurator which can load serialized model files for
configuration.

For more details, please refer to the the
news page:

We thank the Sovereign Tech Fund for kindly championing these
releases.

Why two simultaneous releases?

Given that downstream users are likely to depend on either Java EE (in
the javax namespace) or on Jakarta EE (in the jakarta namespace) in
their projects, it was deemed important for logback to support both EE
alternatives.

As such, logback 1.3.x supports Java EE whereas logback 1.4.x supports
Jakarta EE, otherwise the two versions are feature identical.

Both 1.3.x and 1.4.x series require the fluent-API introduced in SLF4J
2.0.x.

The 1.3.x series requires Java 8 at runtime. If you wish to build
logback from source, you will need Java 9.

The 1.4.x series requires Java 11 at build time and at runtime.

Groovy configuration:

Support for Groovy configuration was dropped for security reasons but
was recovered by Tucker Pelletier (virtualdogbert). See:

  https://github.com/virtualdogbert/logback-groovy-config

Benchmarks:

For benchmarking figures please see:

  http://logback.qos.ch/performance.html

Reproducible builds:

Recent logback releases are reproducible. This means that anyone
checking out the code corresponding to the release version from github
and building that local copy, will get obtain an identical binary to
the binary found on Maven central. Note that due to issue MJAR-275
with the module-info.java produced in earlier java versions,
reproducible builds require Java 19.
