 Upcoming release - coreboot 24.02
 ========================================================================
 
-The 24.02 release is scheduled for Mid February, 2024
+The 24.02 release is scheduled for February 19, 2024. The next release,
+which will be 24.05, is scheduled for mid-May.
 
+The coreboot project is happy to announce our next release for February
+2024. Over the past three months, our contributors have focused on
+refining the coreboot codebase, generally prioritizing cleanup and
+quality enhancements. We extend our gratitude to all the contributors
+who have dedicated their time and expertise. Thank you for your
+invaluable contributions to this vital phase of maintenance and
+optimization.

-* The chip and board additions and removals will be updated right

+### acpi: Add Arm IO Remapping Table structures
+
+Input Output Remapping Table (IORT) represents the IO topology of an Arm
+based system.
+
+Document number: ARM DEN 0049E.e, Sep 2022
+
+
+### acpi: Add PPTT support
+
+This patch adds code to generate Processor Properties Topology Tables
+(PPTT) compliant to the ACPI 6.4 specification.
+
+ - The 'acpi_get_pptt_topology' hook is mandatory once ACPI_PPTT is
+   selected. Its purpose is to return a pointer to a topology tree,
+   which describes the relationship between CPUs and caches. The hook
+   can be provided by, for example, mainboard code.
+
+Background: We are currently working on mainboard code for qemu-sbsa and
+Neoverse N2. Both require a valid PPTT table. Patch was tested against
+the qemu-sbsa board.
+
+
+### acpi: Add support for WDAT table
+
+This commit lays the groundwork for implementing the ACPI WDAT (Watchdog
+Action Table) table specification. The WDAT is a special ACPI table
+introduced by Microsoft that describes the watchdog for the OS.
+
+Platforms that need to implement the WDAT table must describe the
+hardware watchdog management operations as described in the
+specification. See “Links to ACPI-Related Documents”
+(http://uefi.org/acpi) under the heading “Watchdog Action Table”.

+
+### lib/jpeg: Replace decoder with Wuffs' implementation
+
+To quote its repo[0]: Wuffs is a memory-safe programming language (and a
+standard library written in that language) for Wrangling Untrusted File
+Formats Safely. Wrangling includes parsing, decoding and encoding.
+
+It compiles its library, written in its own language, to a C/C++ source
+file that can then be used independently without needing support for the
+language. That library is now imported to src/vendorcode/wuffs/.
+
+This change modifies our linters to ignore that directory because it's
+supposed to contain the wuffs compiler's result verbatim.
+
+Nigel Tao provided an initial wrapper around wuffs' jpeg decoder that
+implements our JPEG API. I further changed it a bit regarding data
+placement, dropped stuff from our API that wasn't ever used, or isn't
+used anymore, and generally made it fit coreboot a bit better. Features
+are Nigel's, bugs are mine.
+
+This commit also adapts our jpeg fuzz test to work with the modified
+API. After limiting it to deal only with approximately screen sized
+inputs, it fuzzed for 25 hours CPU time without a single hang or crash.
+This is a notable improvement over running the test with our old decoder
+which crashes within a minute.
+
+Finally, I tried the new parser with a pretty-much-random JPEG file I
+got from the internet, and it just showed it (once the resolution
+matched), which is also a notable improvement over the old decoder which
+is very particular about the subset of JPEG it supports.
+
+In terms of code size, a QEmu build's ramstage increases
+from 128060 bytes decompressed (64121 bytes after LZMA)
+  to 172304 bytes decompressed (82734 bytes after LZMA).
