A new history database.
A new module dependency resolver that resolves modular context and handles stream expansion properly.
DNF 4
Fedora 29 provides the *DNF* package manager version 4. Notable changes include:
Fedora Scientific Vagrant Box
For full information about DNF 4, see the link:++https://src.fedoraproject.org/rpms/dnf/blob/master/f/dnf.spec#_496++[DNF] and link:++https://src.fedoraproject.org/rpms/libdnf/blob/master/f/libdnf.spec#_250++[libdnf] spec changelogs.
Improved support for DBus tasks (link:++https://github.com/rhinstaller/anaconda/pull/1491++[anaconda/1491])
New Fedora Workstation installations hide the boot menu by default
Note that due to improvements in modularity implementation and dependency resolution, you may encounter errors with older modular repositories such as Fedora 28 if you use them with the upgraded DNF version. Also note that ongoing DNF stack consolidation and a large amount of existing Python code being rewritten into `libdnf` (in {cpp} with SWIG bindings to Python), while the DNF team put an emphasis on preserving compatibility and maintaining an identical user experience, there may be differences and regressions due to the scope and nature of this work.
See xref:f29@fedora:release-notes:sysadmin/System_Utilities.adoc#_grub_menu_hidden_by_default[System Utilities] for details.
Several new options which enable you to change encryption settings (`--luks-version`, `--pbkdf`, and `--pbkdf-memory`) are now available for Kickstart commands [command]`autopart`, [command]`logvol`, [command]`part`, and [command]`raid`.
Some installation tasks now run in DBus modules (link:++https://github.com/rhinstaller/anaconda/pull/1502++[anaconda/1502])
Support for platform pseudo-modules - see `module_platform_id` in the `dnf.conf(5)` man page.
The Anaconda modularization effort will continue in subsequent Fedora releases.
The Fedora Scientific spin now ships as a [appplication]*Vagrant* box in addition to an ISO image, allowing you to bypass the installation process and run it straight in a virtual machine. See xref:f29@fedora:release-notes:sysadmin/Virtualization.adoc#_fedora_scientific_vagrant_box[the Virtualization section] for details.
The Manual Partitioning screen will now display a drop-down menu which allows you to select the LUKS version if the volume or partition is being encrypted. The menu is hidden if you do not use encryption on the volume or partition.
The storage configuration DBus module has been extended (link:++https://github.com/rhinstaller/anaconda/pull/1458++[anaconda/1458], link:++https://github.com/rhinstaller/anaconda/pull/1514++[anaconda/1514], link:++https://github.com/rhinstaller/anaconda/pull/1513++[anaconda/1513], link:++https://github.com/rhinstaller/anaconda/pull/1507++[anaconda/1507])
This release brings additional progress on Anaconda modularization, an initiative that began in previous releases:
When using a Kickstart file in that requires a default LUKS passphrase to finish partitioning, Anaconda in text mode will now pause and prompt you to enter the passphrase.
