The breadcrumb badge (`schema ✕`) is also a one-click way back to data. - **Menus everywhere** - macOS uses the native menu bar; Windows and Linux draw an equivalent in-app `File`/`View` bar with the same commands (`Ctrl` in place of `⌘`). diff --git a/scripts/download_icebug.sh b/scripts/download_icebug.sh index 6434573..e13e62f 100755 --- a/scripts/download_icebug.sh +++ b/scripts/download_icebug.sh @@ -12,7 +12,7 @@ PROJECT_DIR="$(cd "$SCRIPT_DIR/.." && pwd)" REPOSITORY="${ICEBUG_GITHUB_REPOSITORY:-Ladybug-Memory/icebug}" TARGET_DIR="${ICEBUG_TARGET_DIR:-$PROJECT_DIR/icebug}" -VERSION="${ICEBUG_VERSION:-13.2}" +VERSION="${ICEBUG_VERSION:-13.4}" OS="$(uname -s)" ARCH="$(uname -m)" diff --git a/scripts/stage_macos_bundle.sh b/scripts/stage_macos_bundle.sh index 929ec25..f72d082 100755 --- a/scripts/stage_macos_bundle.sh +++ b/scripts/stage_macos_bundle.sh @@ -149,7 +149,7 @@ stage_transitive_deps() { for t in "${targets[@]}"; do # A dylib's own install-ID (otool -D) is listed as the first otool -L # line but is not a dependency: staging it would duplicate the file - # under the ID basename (e.g. liblbug.0.21.1.dylib's ID + # under the ID basename (e.g. liblbug.0.21.2.dylib's ID # @rpath/liblbug.0.dylib pulled a stale brew ladybug copy + its # openssl4 deps).
