 # 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
