Linux
Em computação, o núcleo ou kernel é o componente central do sistema operacional da maioria dos computadores; ele serve de ponte entre aplicativos e o processamento real de dados feito a nível de hardware. As responsabilidades do núcleo incluem gerenciar os recursos do sistema. Wikipédia
Linux 5.7
Linus Torvalds fez o anuncio de lançamento no dia 30 de maio de 2020.
"So we had a fairly calm last week, with nothing really screaming
"let's delay one more rc". Knock wood - let's hope we don't have
anything silly lurking this time, like the last-minute wifi regression
we had in 5.6..
But embarrassing regressions last time notwithstanding, it all looks
fine. And most of the discussion I've seen the last week or two has
been about upcoming features, so the merge window is now open and I'll
start processing pull requests tomorrow as usual. But in the meantime,
please give this a whirl.
We've got a lot of changes in 5.7 as usual (all the stats look normal
- but "normal" for us obviously pretty big and means "almost 14
thousand non-merge commits all over, from close to two thousand
developers"), So the appended shortlog is only the small stuff that
came in this last week since rc7.
Go test,
Linus"

Instalação
Você pode aguardar a chegada dessa versão do Linux em seu sistema operacional GNU/Linux, pode também instalar manualmente, ou pode aproveitar e se tornar um pouquinho mais livre usando o kernel Linux 100% livre, para isso temos o Linux Libre sem blobs (Binary Blob é um termo usado em certos projetos open source para descrever um código objeto para o qual não se disponibiliza o seu código-fonte).
Para mais detalhe da instalação do Linux Libre confira nossa matéria abaixo.
