# Version 20.0.0.0
-* Compiling and running gem5 with Python 3 is now fully supported.
-* Compiling and running gem5 with GCC 8 and 9 is now supported.
-* Scons-based tests have been migrated to the testlib framework. Please consult TESTING.md for more information on how these may be run.
-* Support for the ALPHA ISA has been dropped.
+Welcome to our first "official" gem5 release!
+gem5 v19.0.0.0 was a "test" release, but this one has release notes, so it must be official!
+
+Thank you to everyone that made this release possible!
+This has been a very productive release with over [70 issues closed](https://gem5.atlassian.net/), over 500 commits, and 31 unique contributors.
+Below are some of the highlights, though I'm sure I've missed some important changes.
+
+## New features
+
+* [gem5-resources repository](https://gem5.googlesource.com/public/gem5-resources/)
+ * This new repository will store all of the *sources* (e.g., code) used to create testing and research resources. This includes disk images, testing binaries, kernel binaries, etc.
+ * Binaries created with the sources are hosted on dist.gem5.org.
+ * Details on the new page for resources: <http://www.gem5.org/documentation/general_docs/gem5_resources>.
* Memory SimObjects can now be initialized using an image file using the image_file parameter.
-* The m5 utility has been revamped with a new build system based on scons, tests, and updated and more consistent feature support.
+* **[USER-FACING CHANGE]** The m5 utility has been revamped with a new build system based on scons, tests, and updated and more consistent feature support.
+ * To build, now use `scons build/<arch>/out/m5`, not `make`.
+ * [Documentation](http://www.gem5.org/documentation/general_docs/m5ops/) coming soon.
* Robust support for marshalling data from a function call inside the simulation to a function within gem5 using a predefined set of rules.
-* Workload configuration pulled out into its own object, simplifying the System object and making workload configuration more modular and flexible.
+ * Developers can specify an ABI for guest<->simulator calls and then "just call functions".
+ * Unifies pseudo-inst, syscall, and other support.
+ * Code within gem5 has been updated. However, users which added new pseudo-ops may have to update their code.
+* **[PYTHON API CHANGE]** Workload configuration pulled out into its own object, simplifying the System object and making workload configuration more modular and flexible.
+ * All full system config/run scripts must be updated (e.g., anything that used the `LinuxX86System` or similar SimObject).
+ * Many of the parameters of `System` are now parameters of the `Workload` (see `src/sim/Workload.py`).
+ * For instance, many parameters of `LinuxX86System` are now part of `X86FsLinux` which is now the `workload` parameter of the `System` SimObject.
+ * See https://gem5-review.googlesource.com/c/public/gem5/+/24283/ and https://gem5-review.googlesource.com/c/public/gem5/+/26466 for more details.
* Sv39 paging has been added to the RISC-V ISA, bringing gem5 close to running Linux on RISC-V.
+ * (Some) Baremetal OSes are now supported.
+* Improvements to DRAM model:
+ * Added support for verifying available command bandwidth.
+ * Added support for multi-cycle commands.
+ * Added new timing parameters.
+ * Added ability to interleave bursts.
+ * Added LPDDR5 configurations.
+* **[Developer change]** We are beginning to document gem5 APIs.
+ * Currently, only SimObjects and the APIs they depend on have been documented.
+ * We are using doxygen to mark "stable APIs" and will use manual code review to make sure the APIs stay stable.
+ * More information will be coming during gem5-20.1 development.
+
+## Removed features
+
+* Support for the ALPHA ISA has been dropped.
+ * All ALPHA ISA code has been removed
+ * Old "rcS" scripts for ALPHA have been removed
+
+## New supported platforms
+
+* Compiling and running gem5 with Python 3 is now fully supported.
+ * Lots of code changes required for this.
+ * There may still be some python code that's not up to date. Please open a [Jira ticket](https://gem5.atlassian.net/) if you find any code that doesn't work with python3.
+* gem5 now supports Ubuntu 20.04.
+* Compiling gem5 with GCC 8 and 9 is now supported.
+* Compiling with clang up to version 9 is now supported.
+
+## Testing improvements
+
+* Scons-based tests have been migrated to the testlib framework.
+ * Tests can now be run with `tests/main.py`, except for the unittests.
+ * Please consult TESTING.md for more information on how these may be run.
+* We are continuing to work on CI tests. Most of the plumbing is there for Google Cloud Build integration. See [the Jira issue](https://gem5.atlassian.net/browse/GEM5-237) for details.
+
+## Other API changes
+
+* **[API CHANGE]** Ruby's prefetcher renamed to RubyPrefetcher.
+ * Any SLICC protocols with prefetchers need to be updated.
+ * Some config scripts for Ruby protocols with prefetchers may need to be updated.
+* **[API CHANGE]** SE mode improvements.
+ * Better support for the mmap and related syscalls.
+ * A new virtual memory area API for tracking SE mode allocations.
+ * When implementing syscalls, the way that guest memory is allocated changes. All code in gem5 is updated, but if there are any external syscalls, they may need be updated.
+* **[COMMAND LINE CHANGE]** The `--disk-image` argument to `fs.py` is now optional.
+ * However, the disk image names *are no longer implied*.
+ * The script still implicitly searches `M5_PATH`, but the name of the disk image must be specified.
+* **[API CHANGE]** SLICC `queueMemory` is now `enqueue`.
+ * All protocol configs must be updated with another message buffer in the memory controllers (directories).
+ * All protocol SLICC files must replace `queueMemoryRead` and `queueMemoryWrite` with `enqueue` to another "special" message buffer named `memQueue`.
+ * This allows finite buffering between the cache controllers and DRAMCtrl.
+* **[API CHANGE]** Added Prefetcher namespace
+ * All prefetchers' names have changed from `*Prefetcher` to `Prefetcher::*`
+ * If you have any prefetchers that are not in the gem5 mainline, your code will likely need to be updated.
+
+## Other changes
+
+* Implemented ARMv8.3-CompNum, SIMD complex number extension.
+* Support for Arm Trusted Firmware + u-boot with the new VExpress_GEM5_Foundation platform
+* Removed author list from source files.
+ * This was originally so future people would know who to contact.
+ * However, it was difficult to maintain and quickly out of date.
+ * Copyright is unchanged.
+* Improvements to gem5's power model.
+* MESI_Three_Level Ruby protocol bugfixes.
+* Ruby functional reads now work in more cases.
+* Indirect branch stats work correctly now.

-'''
-Global configuration module which exposes two types of configuration
-variables:
-
-1. config
-2. constants (Also attached to the config variable as an attribute)
-
-The main motivation for this module is to have a centralized location for
-defaults and configuration by command line and files for the test framework.
-
-A secondary goal is to reduce programming errors by providing common constant
-strings and values as python attributes to simplify detection of typos.
-A simple typo in a string can take a lot of debugging to uncover the issue,
-attribute errors are easier to notice and most autocompletion systems detect
-them.
-
-The config variable is initialzed by calling :func:`initialize_config`.
-Before this point only ``constants`` will be availaible. This is to ensure
-that library function writers never accidentally get stale config attributes.
-
-Program arguments/flag arguments are available from the config as attributes.
-If an attribute was not set by the command line or the optional config file,
-then it will fallback to the `_defaults` value, if still the value is not
-found an AttributeError will be raised.
-
-:func define_defaults:
- Provided by the config if the attribute is not found in the config or
- commandline. For instance, if we are using the list command fixtures might
- not be able to count on the build_dir being provided since we aren't going
- to build anything.
-
-:var constants:
- Values not directly exposed by the config, but are attached to the object
- for centralized access. I.E. you can reach them with
- :code:`config.constants.attribute`. These should be used for setting
- common string names used across the test framework.
- :code:`_defaults.build_dir = None` Once this module has been imported
- constants should not be modified and their base attributes are frozen.

+Global configuration module which exposes two types of configuration
+variables:
+
+1. config
+2. constants (Also attached to the config variable as an attribute)
+
+The main motivation for this module is to have a centralized location for
+defaults and configuration by command line and files for the test framework.
+
+A secondary goal is to reduce programming errors by providing common constant
+strings and values as python attributes to simplify detection of typos.
+A simple typo in a string can take a lot of debugging to uncover the issue,
+attribute errors are easier to notice and most autocompletion systems detect
+them.
+
+The config variable is initialzed by calling :func:`initialize_config`.
+Before this point only ``constants`` will be availaible. This is to ensure
+that library function writers never accidentally get stale config attributes.
+
+Program arguments/flag arguments are available from the config as attributes.
+If an attribute was not set by the command line or the optional config file,
+then it will fallback to the `_defaults` value, if still the value is not
+found an AttributeError will be raised.
+
+:func define_defaults:
+ Provided by the config if the attribute is not found in the config or
+ commandline. For instance, if we are using the list command fixtures might
+ not be able to count on the build_dir being provided since we aren't going
+ to build anything.
+
+:var constants:
+ Values not directly exposed by the config, but are attached to the object
+ for centralized access. I.E. you can reach them with
+ :code:`config.constants.attribute`. These should be used for setting
+ common string names used across the test framework.
+ :code:`_defaults.build_dir = None` Once this module has been imported
+ constants should not be modified and their base attributes are frozen.
