 # Revision history for ghcup
 
+## 0.1.19.2 -- 2023-2-24
+
+* Follow-up fix for JFS/ReiserFS and other filesystem that don't support `d_type`, fixes [#787](https://github.com/haskell/ghcup-hs/issues/787)
+    - the previous release had a bug that invalidated that broke it
+* Implement 'latest-prerelease' tag wrt [#788](https://github.com/haskell/ghcup-hs/issues/788)
+* Fix 'Could not parse version of stray directory.DS_Store' warnings on macOs wrt [#797](https://github.com/haskell/ghcup-hs/issues/797)
+

+
+* Fix GHCup on JFS/ReiserFS and other filesystem that don't support `d_type`, fixes [#766](https://github.com/haskell/ghcup-hs/issues/766)
+* Don't fail on setModificationTime, fixes [#784](https://github.com/haskell/ghcup-hs/issues/784) and many GitHub actions issues
+* Make armv7/aarch64 linux binaries more portable (built on Debian buster)
+* Improve usability on 'ghcup config add-release-channel', fixes [#751](https://github.com/haskell/ghcup-hs/issues/751)
+* Make version shortcuts work with 'ghcup set', fixes [#757](https://github.com/haskell/ghcup-hs/issues/757)

+## Distribution policies
+
+Like most Linux distros and other distribution channels, GHCup also
+follows certain policies. These are as follows:
+
+1. The end-user experience is our primary concern
+    - ghcup in CI systems as a use case is a first class citizen
+2. We strive to collaborate with all maintainers of all the tools we support and maintain a good relationship
+3. We may fix build system or other distribution bugs in upstream bindists
+    - these are always communicated upstream
+4. We may even patch source code of supported tools in very rare cases if that is required to ensure that the end-user experience does not break
+    - we'll first try to upstream any such required patch and request a new release to avoid downstream patching
+    - patches will be communicated to the maintainers either way and we'll strive to get their review
+    - they will also be communicated to the end-user
+    - they will be uploaded along with the bindist
+    - we will avoid maintaining long-running downstream patches (currently zero)
+5. We may add bindists for platforms that upstream does not support
+    - this is currently the case for GHC for e.g. Alpine and possibly FreeBSD in the future
+    - this is currently also the case for stack on darwin M1
+    - we don't guarantee for unofficial bindists that the test suite passes at the moment (this may change in the future)
+6. We GPG sign all the GHCup metadata as well as the unofficial bindists
+    - any trust issues relating to missing checksums or GPG signatures is a bug and given high priority

+    - in the upper half, click on "New..."
+    - enter `CABAL_DIR` under "Variable name" and based on the installation destination from step 1. enter the device directory + `cabal` subdir (default `C:\cabal`)
+    - click "OK" at the bottom
+    - click "OK" at the bottom
+    - click "OK" at the bottom
+3. Install tools
+    - open powershell
+    - run `ghcup install ghc --set recommended`
+    - run `ghcup install cabal latest`
+    - run `ghcup install stack latest`
+    - run `ghcup install hls latest`
+    - run `cabal update`
+4. Update msys2
+    - run `ghcup run -m -- pacman --noconfirm -Syuu`
+    - run `ghcup run -m -- pacman --noconfirm -Syuu`
+    - run `ghcup run -m -- pacman --noconfirm -S --needed curl autoconf mingw-w64-x86_64-pkgconf`
+    - run `ghcup run -m -- pacman --noconfirm -S ca-certificates`
+5. Update cabal config
+    - go to e.g. `C:\cabal` (based on device you picked in 1.)
+    - open file `config`
+    - uncomment `extra-include-dirs` (the `-- `) and add the value (depending on installation destination you chose in 2.), e.g. `C:\msys64\mingw64\include`... so the final line should be `extra-include-dirs: C:\msys64\mingw64\include`
+    - uncomment `extra-lib-dirs` and do the same, adding `C:\msys64\mingw64\lib`
+    - uncomment `extra-prog-path` and set it to `C:\ghcup\bin, C:\cabal\bin, C:\msys64\mingw64\bin, C:\msys64\usr\bin`, depending on your install destinations from 1. and 2.
+6. Set up msys2 shell
+    - run `ghcup run -m -- sed -i -e 's/db_home:.*$/db_home: windows/' /etc/nsswitch.conf` to make the HOME in your msys2 shell match the one from windows
+    - make a desktop shortcut from `C:\msys64\msys2_shell.cmd`, which will allow you to start a proper msys2 shell
+    - run `ghcup run -m -- sed -i -e 's/#MSYS2_PATH_TYPE=.*/MSYS2_PATH_TYPE=inherit/' /c/msys64/msys2.ini`
+    - run `ghcup run -m -- sed -i -e 's/rem set MSYS2_PATH_TYPE=inherit/set MSYS2_PATH_TYPE=inherit/' /c/msys64/msys2_shell.cmd`
+
+All set. You can run `cabal init` now in an empty directory to start a project.

-   with the Work to which such Contribution(s) was submitted. If You
-   institute patent litigation against any entity (including a
-   cross-claim or counterclaim in a lawsuit) alleging that the Work
-   or a Contribution incorporated within the Work constitutes direct
-   or contributory patent infringement, then any patent licenses
-   granted to You under this License for that Work shall terminate
-   as of the date such litigation is filed.
-

-   Work or Derivative Works thereof in any medium, with or without
-   modifications, and in Source or Object form, provided that You
-   meet the following conditions:
-
-   (a) You must give any other recipients of the Work or

-   (c) You must retain, in the Source form of any Derivative Works
-       that You distribute, all copyright, patent, trademark, and
-       attribution notices from the Source form of the Work,
-       excluding those notices that do not pertain to any part of
-       the Derivative Works; and
-
-   (d) If the Work includes a "NOTICE" text file as part of its
-       distribution, then any Derivative Works that You distribute must
-       include a readable copy of the attribution notices contained
-       within such NOTICE file, excluding those notices that do not
-       pertain to any part of the Derivative Works, in at least one
-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       documentation, if provided along with the Derivative Works; or,
-       within a display generated by the Derivative Works, if and
-       wherever such third-party notices normally appear. The contents
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution
-       notices within Derivative Works that You distribute, alongside

-   the terms of any separate license agreement you may have executed
-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.
-
-7. Disclaimer of Warranty. Unless required by applicable law or
-   agreed to in writing, Licensor provides the Work (and each
-   Contributor provides its Contributions) on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-   whether in tort (including negligence), contract, or otherwise,

-   negligent acts) or agreed to in writing, shall any Contributor be
-   liable to You for damages, including any direct, indirect, special,
-   incidental, or consequential damages of any character arising as a
-   result of this License or out of the use or inability to use the
-   Work (including but not limited to damages for loss of goodwill,
-   work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses), even if such Contributor
-   has been advised of the possibility of such damages.
-
-9. Accepting Warranty or Additional Liability. While redistributing
-   the Work or Derivative Works thereof, You may choose to offer,
-   and charge a fee for, acceptance of support, warranty, indemnity,
-   or other liability obligations and/or rights consistent with this
-   License. However, in accepting such obligations, You may act only
-   on Your own behalf and on Your sole responsibility, not on behalf
-   of any other Contributor, and only if You agree to indemnify,
-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-PREAMBLE
-The goals of the Open Font License (OFL) are to stimulate worldwide

-
-The OFL allows the licensed fonts to be used, studied, modified and
-redistributed freely as long as they are not sold by themselves. The
-fonts, including any derivative works, can be bundled, embedded, 
-redistributed and/or sold with any software provided that any reserved
-names are not used by derivative works. The fonts and derivatives,
-however, cannot be released under any other type of license. The
-requirement for fonts to remain under this license does not apply
-to any document created using the fonts or their derivatives.
