+
+v0.1.8
+======
+* Fixes on some float to int x87 convertions opcodes

+* Added libturbojpeg wrapping (and a hack for zoom to force using native one)
+* Added BOX86_SAFEMMAP env. var.
+* Reworked dynarec memory manager
+* Added a few opcodes
+* Improve elfloader to not force PltResolver all the time (fixing SuperHexagon and maybe other)
+* Reworked Exet and Cancel Thread mecanism
+* Added wrapped libldap_r and liblber library (used by wine)
+* Reworked Dynarec block handling, and remove the "AddMark" mecanism that wasn't efficient enough
+* Added TokiTori 2+ detection and runtime patch on PI
+* Fixes on elfloader with TLS object
+
+v0.1.6
+======
+* Changes in Dynarec to make flags optimizations before CALL and RET opcode less aggressive
+* Added Vulkan wrapper
+* Improved wrapping of SDL_mixer/ SDL2_mixer lib
+* Improved wrapping of some gtk structures
+* Added a quick and dirty wrapping of Gtk3 (based on current gtk2)
+* Improved the signal handling, should be more stable now (the signal handler from syscall still need some works)
+* Added RK3399 profile, and some hints to build the 32bits box86 on 64bits OS
+* Fixed some wrapped printf formating not handled correctly
+* Fixed some buserror with the new LOCK mecanism handling
+* A few more Dynarec opcodes added
+* If winedbg is tried to be launched, exit without launching it (it doesn't work anyway)
+
 v0.1.4

 * Change in Dynarec memory handling, to simplify it (and hopefully optimized it)

-A note about 64-bit platforms
+Notes about 64-bit platforms
 ----
 
 Because Box86 works by directly translating function calls from x86 to host system, the host system (the one Box86 is running on) needs to have 32-bit libraries. Box86 doesn't include any 32-bit <-> 64-bit translation. So basically, to run Box86 on, for example, an ARM64 platform, you will need to build Box86 for ARM 32-bit, and also need to have a chroot with 32-bit libraries.
 
-Also note that, even if, on day, there is a Box86_64, this one will only be able to run x86_64 binaries on 64-bit platforms. You will still need Box86 (and see 32-bit chroot) to run x86 binaries (in fact, the same is the case on actual x86_64 Linux).

 A note about Unity game emulation
 ----
 
-Running Unity games is a hit or miss for now. Unity uses Mono (which uses signals that are not well emulated enough), and a runtime embedded in the main binary. A solution would be to use a native version of the libmono library used by Unity (it can be found here: https://github.com/Unity-Technologies/mono and needs to be built from source). But the wrapping of this lib is tricky, and not done for now, so the only solution is to emulate everything. The tricky part is to emulate the "JIT" code emitted by Mono, however with he new "protected memory" mechanism implemented it is running with correct performance now.
+Running Unity games is a hit or miss for now. Unity uses Mono (which uses signals that are not well emulated enough), and a runtime embedded in the main binary. A solution would be to use a native version of the libmono library used by Unity (it can be found here: https://github.com/Unity-Technologies/mono and needs to be built from source). But the wrapping of this lib is tricky, and not done for now, so the only solution is to emulate everything. The tricky part is to emulate the "JIT" code emitted by Mono, however with the new "protected memory" mechanism implemented it should be running with correct performance now.
 You should also note that some Unity3D games require OpenGL 3+ which can be tricky to provide on ARM SBC (single-board computers) for now.
 
 TL;DR: Not all Unity games work and can require a high OpenGL profile, but the speed, for the ones running, should be correct now.

-Linux Steam can run now with box86. But it's still a bit unstable., and not everything works. First is steam crashes after the Sign in, you may need to add libappindicator. On debian it's `sudo apt install libappindicator1`.
-Once open, Steam will only work on "Small mode". So go in the "View" menu and witch to Small view (or Compact view?), else the list will stay empty (this is because some steam component used in the browser view are only 64bits now).
-Final word, to avoid the "libc.so.6 is absent" message, you can use `STEAMOS=1` and `STEAM_RUNTIME=1` export. 
-(Steam for Windows install fine but doesn't work yet)

+Final words, to avoid the "libc.so.6 is absent" message, you can use `STEAMOS=1` and `STEAM_RUNTIME=1` as environment variables. 
+(Steam for Windows installs fine but doesn't work yet)
+Some Steam games (most Source engine games, like "Portal" or "Half-Life 2") use libtcmalloc. Box86 will detect it and will try to LD_PRELOAD it, for better compatibility. While it should work without the aformentionned feature, it is safer to add it to your system if you intend to play those game (something like `sudo apt install libtcmalloc-minimal4` to install it on Debian and Debian's deriatives)

-Wine is now partly supported. Wine integreted program all runs, annd some windows program and games now run fine. Don't forget most Windows games use Direct3D, that may require a complete OpenGL driver and as high profile as possible (and gl4es with ES2 backend have issue with Wine for now). Also, vulkan is not wrapped on box86, so vk3d is not usable yet, even if supported by the hardware.

Also, vulkan is not wrapped on box86, so vk3d is not usable yet, even if supported by the hardware.
+Note: if you plan to use box86 with Wine on Raspberry Pi 3 or earlier, those models use a default OS that have a kernel with a 2/2 Split (meaning 2G of space for user program, and 2G of space for the Kernel). This is not compatible with Wine programs that needs to access memory > 2Gb address. So you'll need to reconfigure your kernel for a 3G/1G split. Use your favorite search engine for instructions on how to do that.

+# The directory containing all PKGBUILDs for BOX86
+## FAQ
+### 1. How to use it?
+Just download the `PKGBUILD-<your-platform>` (no need to download the whole repository), go to directory where you downloaded and type:
+```sh
+mv ./PKGBUILD-<your-platform> ./PKGBUILD
+cd ..
+makepkg -si
+```
+This will copy the PKGBUILD for your platform (where you type your platform name instead of `<your-platform>`), build it and install the PKGBUILD on 32-bit Archlinux ARM.
+
+In the future, I might try to do an unified PKGBUILD for all platforms that will recognize your platform automatically.
+
+### 2. What platforms are currently supported.
+All specified in [COMPILE.md](../COMPILE.md).
+
+### 3. Any advantages with that sollution?
+This might give you some advantages like those:
+- automatic updates (with some AUR frontends like [`pamac-aur`](https://aur.archlinux.org/packages/pamac-aur/) or [`yay`](https://aur.archlinux.org/packages/yay));
+- easily uninstall with `pacman -R` when no needed (no need other scripts nor Makefile to do this);
+- your `box86` installation is recognized as a package (where it wasn't when installing with `make install`).
