+# We're Back!
+
+It has been one year and four days since the last release of Redox OS! In this
+time, we have been hard at work improving the Redox ecosystem. Much of this work
+was related to [relibc](https://gitlab.redox-os.org/redox-os/relibc), a new C
+library written in Rust and maintained by the Redox OS project, and adding new
+packages to the [cookbook](https://gitlab.redox-os.org/redox-os/cookbook). We
+are proud to report that we have now far exceeded the capabilities of `newlib`,
+which we were using as our system C library before. We have added many important
+libraries and programs, which you can see listed below.
+
+## Standard Images
+
+You can download the 0.5.0 images
+[here](https://gitlab.redox-os.org/redox-os/redox/-/jobs/10824/artifacts/browse/build/img/).
+
+At first glimpse, the standard ISO does not look much different from 0.3.5, our
+last real release. We still have the same login screen, and the same default
+background and applications. This, in and of itself, was an accomplishment. Work
+on [relibc](https://gitlab.redox-os.org/redox-os/relibc) was intense, and
+touched nearly every part of the system.
+
+Once one digs a little deeper, the changes become more obvious. The event system
+was redesigned to provide correct support for `select` and `poll`, and complete
+memory mapping support was implemented. Pthreads was implemented, and also a
+number of signal-related system calls. The whole of these changes provided
+better support for LLVM, and from that, `rustc` and `mesa` with `llvmpipe`.
+
+In addition, there are new images based on new bootloaders for both coreboot and
+EFI. Significant work has been done to provide libraries for EFI Rust
+development, and to develop coreboot payloads in Rust. Either bootloader project
+can be forked and repurposed as desired. See the following projects:
+
+- [bootloader-coreboot](https://gitlab.redox-os.org/redox-os/bootloader-coreboot) -
+  Coreboot payload that can boot Redox
+- [bootloader-efi](https://gitlab.redox-os.org/redox-os/bootloader-efi) - EFI
+  bootloader for Redox
+- [coreboot-table](https://gitlab.redox-os.org/redox-os/coreboot-table) - A

+- [uefi_std](https://gitlab.redox-os.org/redox-os/uefi_std) - UEFI runtime
+
+## New Packages
+
+The result of the [relibc](https://gitlab.redox-os.org/redox-os/relibc) work can
+be seen in the massive addition of new packages that can be added to your
+`filesystem.toml` when building locally, or installed with `pkg install`. You
+can see all available packages and versions
