+
+### About
+
+Grml is a Debian-based live system focusing on the needs of system administrators.
+The {{< param release_version >}} release provides fresh software packages from Debian testing/forky.
+As usual it also incorporates up to date hardware support and fixes known bugs from previous Grml releases.
+
+About [the codename]({{< ref "faq#releasename" >}}).
+
+### Important changes
+
+* This release is based on Debian testing/forky as of September 2026.
+* [GNU Screen 5.0.1](https://lwn.net/Articles/987700/) landed. The required configuration changes are not backwards compatible. Users of our grml screenrc must either upgrade or use the [screenrc_v4](https://grml.org/console/screenrc_v4) file with GNU Screen 4.9.
+
+### New and removed features
+
+New software since the Grml 2026.04 release is included, and we continued to clean up the house. Noteworthy changes are:
+
+#### [grml-live](https://github.com/grml/grml-live/) - build system for creating Grml (based) Linux live systems:
+
+* grml-live now requires Linux user namespaces in the build environment. Unfortunately docker and other containerization tools do not provide Linux user namespaces inside containers. This was prompted by systemd changes, and took a substantial effort. Daily images were not built between 2026-06-10 and 2026-09-02.
+* Reading configuration from `grml-live.conf` was removed.
+* New command line syntax. chroot-based workflows are temporarily unsupported and will be restored at a later time.
+* Not shipped on grml-full anymore. Please use grml-live directly from git.
+* Remaining 32-bit i386 architecture support was removed.
+
+Detailed changes: [grml-live v0.56.0 to d37c392](https://github.com/grml/grml-live/compare/v0.56.0...d37c392310b4760fe848a9739089ee4949598298)
+
+#### [grml-debootstrap](https://github.com/grml/grml-debootstrap) - Debian system install tool:
+
+* Debian "forky" can now be selected in the dialog frontend
+* `/etc/kernel-img.conf` is no longer created in the target system, rely on Debian defaults instead.
+* `FIXED_DISK_IDENTIFIERS=yes` was implemented for GPT and Raspberry Pi images, and the identifiers are derived from  [SOURCE_DATE_EPOCH](https://reproducible-builds.org/docs/source-date-epoch/).
+
+Detailed changes: [grml-debootstrap v0.127 to v0.130](https://github.com/grml/grml-debootstrap/compare/v0.127...v0.130)
+
+### Bits & bolts
+
+* Linux kernel **{{< param kernel_version >}}**
+* `exfat` support is now available in the initramfs, for booting from exfat-formatted USB devices.
+* `grml2usb`: when `grub-install` fails, add hint for required GNU GRUB packages.
+* GRUB now [sources hook files](https://github.com/grml/grml-live/commit/be75e4ba94971122e472e3c64705e9524a0aea2f) and respects [${extraopts}](https://github.com/grml/grml-live/commit/3f4b93ffb516271321ea0714856008f15a9b4c03).
+* GRUB `boot_hybrid.img` is bundled in the ISO9660 filesystem for easier remastering.
+* The very old `save-config` and `restore-config` scripts have been removed.
+* Fixed [19 issues](https://github.com/search?q=org%3Agrml+closed%3A2026-04-29..2026-09-03+reason%3Acompleted&type=issues&ref=advsearch) and [144 PRs](https://github.com/search?q=org%3Agrml+closed%3A2026-04-29..2026-09-03&type=pullrequests&ref=advsearch).
+
+### Packages
+
+Details about shipped packages and their versions in Grml are available in the [Debian section](/files/#debian).
+
+Packages for individual Grml software is now also available directly from their GitHub release pages, for example [grml2usb](https://github.com/grml/grml2usb/releases).
+
+### Updates
+
+Packages are taken from Debian testing/forky, as of {{< format_date_long release_packages_date >}}.
+
+The following packages have been added (excluding e.g. `lib*`, `fonts*`, `*-{base,bin,common,core,data}`, `{gcc,cpp}-*`, `perl*`, `python*`, `ruby*` and kernel image):
+
+* `3cpio`: a dependency of initramfs-tools
+* `ovmf` (amd64) and `qemu-efi-aarch64`: EFI Firmware for QEMU, useful to verify EFI bootloader setup. Thanks to [Sebastian Pipping](https://github.com/hartwork) for the [suggestions](https://github.com/grml/grml-live/issues/557).
+* `pydf`
+
+The following packages have been removed/replaced (excluding `lib*`, `fonts*`, `*-{base,bin,common,core,data}`, `{gcc,cpp}-*`, `perl*`, `python*`, `ruby*` and kernel image):
+
+* `speedtest-cli`: [removed from Debian](https://bugs.debian.org/1136353)
+* `squashfs-tools`: dependency of grml-live
+* `tpm-udev`: [removed from Debian testing](https://tracker.debian.org/news/1727150/tpm-udev-removed-from-testing/)
