 # Revision history for ghcup
 
-## 0.1.17.4 -- 2021-11-13
-
-* add `--metadata-caching` option, allowing to also disable yaml metadata caching wrt [#278](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/278)
-* make upgrading ghcup in TUI more pleasant wrt [#276](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/276)
-* fix parsing of atypical GHC versions (e.g. `8.10.5-patch1`)
-* fix compiling HLS dynamically linked, also see [#245](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/245)
-* redo (and break) some of the `ghcup compile <tool>` interface, improving patch options and setting custom cabal.project files
-* avoid redundant update warnings wrt [#283](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/283)
-
-## 0.1.17.3 -- 2021-10-27
-
-* clean up during unpack failures as well
-* migrate te aeson-2.0.1.0
-* switch to yaml-streamly to fix performance regression wrt [#270](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/270)
-* use [github.com/haskell/ghcup-metadata](https://github.com/haskell/ghcup-metadata) for metadata file download (better caching)
-
 ## 0.1.17.2 -- 2021-09-30
 
 * Honour GHC bootstrap compiler during git clone stages wrt [#250](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/250)

-## Caching
-
-GHCup has a few caching mechanisms to avoid redownloads. All cached files end up in `~/.ghcup/cache` by default.
-
-### Downloads cache
-
-Downloaded tarballs (such as GHC, cabal, etc.) are not cached by default unless you pass `ghcup --cache` or set caching
-in your [config](#configuration) via `ghcup config set cache true`.
-
-### Metadata cache
-
-The metadata files (also see [github.com/haskell/ghcup-metadata](https://github.com/haskell/ghcup-metadata))
-have a 5 minutes cache per default depending on the last access time of the file. That means if you run
-`ghcup list` 10 times in a row, only the first time will trigger a download attempt.
-
-### Clearing the cache
-
-If you experience problems, consider clearing the cache via `ghcup gc --cache`.

-
-See [config.yaml](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/data/config.yaml)

-### Which versions get installed?
-
-GHCup has two main channels for every tool: **recommended** and **latest**. By default, it installs *recommended*.
-
-*latest* follows the latest release of every tool, while *recommended* is at the discretion of the GHCup maintainers and based on community adoption (hackage libraries, tools like HLS, stackage support, etc.) and known bugs.
