+## 0.1.22.0 -- 2024-03-13
+
+### New features
+
+* A help screen/tutorial in the TUI by @lsmor (Luis Morillo)
+* Beef up `--overwrite-version`, fixes [#998](https://github.com/haskell/ghcup-hs/issues/998)
+  * e.g. `ghcup compile hls -g master --overwrite-version='%v-%h' --ghc 9.4.8` will produce a binary called `haskell-language-server-wrapper-<version-from-cabal-file>-<short-git-commit-hash>`... refer to `ghcup compile hls --help` for more information
+* Allow to set ghcup msys2 environment wrt [#982](https://github.com/haskell/ghcup-hs/issues/982)
+* Add mechanism to warn on new metadata versions, fixes [#860](https://github.com/haskell/ghcup-hs/issues/860)
+* Add pre-install message support via ghcup metadata, wrt [#1016](https://github.com/haskell/ghcup-hs/issues/1016)
+* Allow to remove all unset versions, fixes [#1019](https://github.com/haskell/ghcup-hs/issues/1019)
+  * e.g.: `ghcup gc --unset`
+
+### Improvements and bug fixes
+
+* Fix potential [HSEC-2024-0002](https://haskell.github.io/security-advisories/advisory/HSEC-2024-0002.html)
+* Fix TUI crash in windows terminal 1.19 [#1013](https://github.com/haskell/ghcup-hs/issues/1013)
+* Clean up on git clone errors, fixes [#1004](https://github.com/haskell/ghcup-hs/issues/1004)
+* Error out on empty UserSettings wrt [#922](https://github.com/haskell/ghcup-hs/issues/922)
+* Fix failure mode when metadata is garbage, fixes [#921](https://github.com/haskell/ghcup-hs/issues/921)
+* Be less confusing when user tries to 'set' ghcup in TUI, fixes [#923](https://github.com/haskell/ghcup-hs/issues/923)
+* Fix prefetch for cross bindists
+* Fix misinterpretation of '+' in URI paths, fixes [#408](https://github.com/haskell/ghcup-hs/issues/408)
+* Stricter (and better) file uri handling
+* Set LD=ld.bfd on Alpine linux during bindist configure
+* Add rocky/void detection
+* Logging improvements
+* Remove the "show all tool" config in the TUI
+* Fix opening changelog on windows
+* Don't remove share dir link prematurely
+* Require user to explicitly choose subcommand for 'ghcup config'
+* Don't download twice when trying stack decoding
+
+### Refactoring and maintenance
+
+* Large TUI code cleanup by @lsmor (Luis Morillo)... more coming up soon
+* Allow building with `tar` instead of `libarchive` (mainly to make contributions easier)
+
+## 0.1.20.0 -- 2023-11-10
+
+### New features
+
+* support TUI on windows thanks to the work from vty and brick maintainers (Chris Hackett, Timofey Zakrevskiy, Jonathan Daugherty, ...), wrt [#912](https://github.com/haskell/ghcup-hs/pull/912)
+* support JS and wasm cross compilers wrt [#838](https://github.com/haskell/ghcup-hs/issues/838), thanks to Sylvain Henry and IOG
+* Support stacks installation strategy and metadata wrt [#892](https://github.com/haskell/ghcup-hs/issues/892)
+  - you can now enable stacks installation method via `ghcup config set url-source '["GHCupURL", "StackSetupURL"]'`... for more information, check the [documentation](https://www.haskell.org/ghcup/guide/#using-stacks-setup-info-metadata-to-install-ghc)
+
+### Improvements and bug fixes
+
+* fix segfault in TUI when hitting enter early wrt [#887](https://github.com/haskell/ghcup-hs/issues/887)
+* Improve key handling in TUI, fixes [#875](https://github.com/haskell/ghcup-hs/issues/875)
+* add explicit support for Void Linux and Rocky Linux (this requires a metadata version bump to `ghcup-0.0.8.yaml`)
+* optparse cli interface now has a test suite thanks to Lei Zhu, wrt [#862](https://github.com/haskell/ghcup-hs/pull/862)
+
+## 0.1.19.4 -- 2023-7-02
+
+* fix missing TUI for aarch64 linux binaries

+
+```sh
+stack config set install-ghc false --global
+stack config set system-ghc  true  --global

+
+### Using stack's setup-info metadata to install GHC
+
+You can now use stack's [setup-info metadata](https://github.com/commercialhaskell/stackage-content/blob/master/stack/stack-setup-2.yaml)
+to install GHC. For that, you can invoke ghcup like so as a shorthand:
+
+```sh
+# ghcup will only see GHC now
+ghcup -s StackSetupURL install ghc 9.4.7
+# this combines both ghcup and stack metadata
+ghcup -s '["GHCupURL", "StackSetupURL"]' install ghc 9.4.7
+```
+
+To make this permanent and combine it with the GHCup metadata, you can add the following to your `~/.ghcup/config.yaml`:
+
+```yaml
+url-source:
+  - GHCupURL
+  # stack versions take precedence
+  # you'll still have access to GHCup provided versions and tools in case they don't exist in stack metadata
+  - StackSetupURL
+```
+
+You can customize or add sections to the setup-info similar to how the [stack documentation](https://docs.haskellstack.org/en/stable/yaml_configuration/#setup-info) explains it. E.g. to change the 9.4.7 bindist, you might do:
+
+```yaml
+url-source:
+  - GHCupURL
+  - StackSetupURL
+  - setup-info:
+      ghc:
+        linux64-tinfo6:
+          9.4.7:
+            url: "https://downloads.haskell.org/~ghc/9.4.7/ghc-9.4.7-x86_64-fedora27-linux.tar.xz"

+```
+
+#### Caveats
+
+The main caveat with using this method is that there's no guarantee that GHCup will pick a compatible HLS bindist
+when you try to install HLS.
+
+Another potential usability issue is that the `latest` and `recommended` shorthands won't work anymore, since
+Stack metadata doesn't have a concept of those and we don't try to be smart when combining the metadatas.

+
+```sh
+git clone https://github.com/emscripten-core/emsdk.git
+cd emsdk
+./emsdk install latest

+```
+
+Instructions are also here: [Download and install — Emscripten 3.1.43-git (dev) documentation](https://emscripten.org/docs/getting_started/downloads.html).

+```sh
+echo 'main = putStrLn "hello world"' > hello.hs
+javascript-unknown-ghcjs-ghc -fforce-recomp hello.hs
+./hello
+```
+
+You can follow the instructions [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/javascript-backend/building#compiling-hello-world).

+```
+
+**Note that some wasm bindists don't work with the master branch of ghc-wasm-meta. GHCup will warn you about such cases prior to installation and point you to the right commit.**
+
+To install, we need to invoke ghcup like so also passing the `--host=<host>` flag (adjust as needed):

 On OS X, in the course of running ghcup you will be given a dialog box to install the command line tools. Accept and the requirements will be installed for you. You will then need to run the command again.
 On Darwin M1 you might also need a working llvm installed (e.g. via brew) and have the toolchain exposed in PATH.

+
 The following distro packages are required: `curl gcc gmp gmake ncurses perl5 libffi libiconv`
 
-Notice that only FreeBSD 13.x is supported. If the installation fails, complaining about `libncursesw.8.so`, you will need to install FreeBSD 12 compat package first, for example, `pkg install misc/compat12x`.
 
 ### Windows
 
+#### Generic
+
 On Windows, msys2 should already have been set up during the installation, so most users should just proceed. If you are installing manually, make sure to have a working mingw64 toolchain and shell.

+### Void Linux
+
+Since void linux can be installed with glibc and musl, it's hard to support correctly with ghcup.
+One way to make ghcup work on **Void Linux musl** is to follow the [Overriding distro detection](../guide/#overriding-distro-detection)

+source ~/.ghcup/env
+ghcup config set platform-override '{ "arch": "A_64", "platform": { "contents": "Alpine", "tag": "Linux" }, "version": "3.17" }'
+ghcup install cabal --set latest
+ghcup install ghc --set latest
+ghcup install stack --set latest
+ghcup install hls --set latest

+This module defines the brick App. The pattern is very simple:

+- Pattern match on the Mode
+- Dispatch drawing/events to the corresponding widget/s
+
+In general each widget should know how to draw itself and how to handle its own events, so this
+module should only contain:
+
+- how to draw non-widget information. For example the footer

+{- **************
+
+A general system inspired by Brick.Form. It uses optics instead of microlenses and it is less generic than
+Brick.Form, but generic enough to serve our purpose.
+
+A Menu consists in
+  a) A state value
+  b) A list of fields. Each field is capable of modifying a part of the state
+  c) some metadata
+
+A field (type MenuField) consists in
+  a) a Lens to a part of the Menu state, so the Menu can call that lens to modify its own state
+  b) an input widget
+
+An input (type FieldInput) consist in
+  a) some state
+  b) a validator function
+  c) a handler and a renderer
+
+We have to use existential types to achive a composable API since every FieldInput has a different
+internal type, and every MenuField has a different Lens. For example:
+  - The menu state is a record (MyRecord {uri: URI, flag : Bool})
+  - Then, there are two MenuField:
+    - One MenuField has (Lens' MyRecord URI) and the other has (Lens' MyRecord Bool)
+    - The MenuFields has FieldInputs with internal state Text and Bool, respectively
+  - Obviously, the MenuField has to be polimorphic in the Lens' and in the Input internal state,
+    But we must hide that polimorphisim (existential), in order to store all MenuField in a List
