Git v2.24.0 Git 2.24 has been released. This blog
post covers the highlights of this release, beginning with feature macros. " Usually, configuring some behavior requires only a single configuration change, like enabling or disabling any of the aforementioned values. But what about when it doesn’t? What do you do when you don’t know which configuration values to change? For example, let’s say you want to live on the bleeding-edge of the latest from upstream Git, but don’t have a chance to discover all the new configurable options. In Git 2.24, you can now opt into feature macros—one Git configuration that implies many others. These are hand-selected by the developers of Git, and they let you opt into a certain feature or adopt a handful of settings based on the characteristics of your repository." | | 7:16p |

[$] Generalizing address-space isolation Linux systems have traditionally run with a single address space that is shared by user and kernel space. That changed with the advent of the Meltdown vulnerability, which forced the merging of kernel page-table isolation (KPTI) at the end of 2017. But, Mike Rapoport said during his 2019
Open Source Summit Europe talk, that may not be the end of the story for address-space isolation. There is a good case to be made for increasing the separation of address spaces, but implementing that may require some fundamental changes in how kernel memory management works. |
