Hello all,
I am happy to announce the simultaneous release of logback
versions 1.3.8 and 1.4.8. Both versions require slf4j-api version
2.0.x or later.
In addition to fixing several outstanding bugs, these releases
add JsonEncoder which outputs logging events in Newline delimited
JSON (ndjson) format. For more details, please refer to the the
news page:
http://logback.qos.ch/news.html
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
checking out the code corresponding to the release version from
github and building it, will generate a binary identical to the
binary found on Maven central.
