After nine months of development, a release of the Cinnamon 4.2 user environment has been formed, within which the Linux Mint distribution developer community is developing fork of the GNOME Shell shell, Nautilus file manager and window manager Mutter, aimed at providing the classic GNOME 2 environment with support for successful interaction elements from GNOME Shell . Cinnamon relies on GNOME components, but these components are shipped as a periodically synchronized fork, not bound by external dependencies to GNOME.

A new release of Cinnamon will be offered in the Linux Mint 19.2 distribution, which is scheduled for release in the coming months. In the near future, packages will be prepared that can be installed in the Linux Mint and Ubuntu from the PPA-repository, without waiting for the new version of Linux Mint.

These are main features:

  • New widgets for creating configurators, simplifying the writing of configuration dialogs and making their design more complete and consistent with the Cinnamon interface was added
  • The search bar is moved to the top in MintMenu, .
  • The Nemo file manager simplifies the process of sharing directories with Samba.
  • Some changes are ported to the Muffin window manager from the Metacity window manager developed by the GNOME project.
  • An applet for printing has been added to the main composition, which is now launched by default.
  • Some internal components were reviewed and simplified, such as DocInfo (processing of recently opened documents) and AppSys (parsing application metadata, identifying application icons, defining entries for menus, etc.)

Linux 5.3 Kernel to be Released

Huge amount of updates, improvements, changes and new features awaits all Linux users
17 September 2019   258

After two months of development, Linus Torvalds introduced the Linux 5.3 kernel release. Among the most notable changes: support for AMD Navi GPUs, Zhaoxi processors, and Intel Speed ​​Select power management technology, the ability to use umwait instructions to wait without using loops, increasing the interactivity utilization clamping mode for asymmetric CPUs, the pidfd_open system call, the ability to use IPv4 addresses from the subnet 0.0.0.0/8, the possibility of hardware acceleration of nftables, support for HDR in the DRM subsystem, integration of the ACRN hypervisor.

In the announcement of the new release, Linus reminded all developers of the main rule of kernel development - maintaining the invariance of behavior for user space components. Changes in the kernel should in no way violate already running applications and lead to user-level regressions. At the same time, a violation of behavior can cause not only a change in the ABI, removal of outdated code or errors, but also an indirect effect of correctly working useful improvements. As a good example, the useful optimization in Ext4 code was discarded, which reduces the number of accesses to the drive by disabling the read-ahead inode table for small I / O requests.

Optimization has led to the fact that, due to a decrease in disk activity, the entropy for the random number generator getrandom () began to accumulate more slowly and in some configurations, under certain circumstances, there could be hangs during loading until the entropy pool is full. Since the optimization is really useful, a discussion arose among the developers, in which it was proposed to eliminate the problem by disabling the default blocking mode of the getrandom () call with the addition of an optional flag to wait for entropy, but such a change will affect the quality of random numbers at the initial stage of loading. In the change rollback commit, Linus noted that he plans to bring the optimization back as soon as the problem with getrandom () is resolved.

The new version adopted 15794 patches from 1974 developers, the patch size is 92 MB (the changes affected 13986 files, 258419 lines of code were added, 599137 lines were deleted). About 39% of all the changes presented in 5.3 are related to device drivers, about 12% of changes are related to updating the code specific to hardware architectures, 11% are connected to the network stack, 3% to file systems and 3% to internal kernel subsystems.
