+title: Release 1.1.0
+short-description: Release notes for 1.1.0
+...
+
+# New features
+
+Meson 1.1.0 was released on 10 April 2023
+## `clang-cl` now accepts `cpp_std=c++20`
+
+Requires `clang-cl` 13 or later.
+
+## coercing values in the option() function is deprecated
+
+Currently code such as:
+```meson
+option('foo', type : 'boolean', value : 'false')
+```
+works, because Meson coerces `'false'` to `false`.
+
+This should be avoided, and will now result in a deprecation warning.
+
+## New `declare_dependency(objects: )` argument
+
+A new argument to `declare_dependency` makes it possible to add objects
+directly to executables that use an internal dependency, without going
+for example through `link_whole`.
+
+## Dump devenv into file and select format
+
+`meson devenv --dump [<filename>]` command now takes an optional filename argument
+to write the environment into a file instead of printing to stdout.
+
+A new `--dump-format` argument has been added to select which shell format
+should be used. There are currently 3 formats supported:
+- `sh`: Lines are in the format `VAR=/prepend:$VAR:/append`.
+- `export`: Same as `sh` but with extra `export VAR` lines.
+- `vscode`: Same as `sh` but without `$VAR` substitution because they do not
+  seems to be properly supported by vscode.
+
+## Feature objects now have an enable_auto_if method
+
+This performs the opposite task of the disable_auto_if method, enabling the
+feature if the condition is true.
+
+## Add a FeatureOption.enable_if and .disable_if
+
+These are useful when features need to be constrained to pass to [[dependency]],
+as the behavior of an `auto` and `disabled` or `enabled` feature is markedly
+different. consider the following case:
+
+```meson
+opt = get_option('feature').disable_auto_if(not foo)
+if opt.enabled() and not foo
+  error('Cannot enable feat when foo is not also enabled')
+endif
+dep = dependency('foo', required : opt)
+```
+
+This could be simplified to
+```meson
+opt = get_option('feature').disable_if(not foo, error_message : 'Cannot enable feature when foo is not also enabled')
+dep = dependency('foo', required : opt)
+```
+
+For a real life example, here is some code in mesa:
+```meson
+_llvm = get_option('llvm')
+dep_llvm = null_dep
+with_llvm = false
+if _llvm.allowed()
+  dep_llvm = dependency(
+    'llvm',
+    version : _llvm_version,
+    modules : llvm_modules,
+    optional_modules : llvm_optional_modules,
+    required : (
+      with_amd_vk or with_gallium_radeonsi or with_gallium_opencl or with_clc
+      or _llvm.enabled()
+    ),
+    static : not _shared_llvm,
+    fallback : ['llvm', 'dep_llvm'],
+    include_type : 'system',
+  )
+  with_llvm = dep_llvm.found()
+endif
+if with_llvm
+  ...
+elif with_amd_vk and with_aco_tests
+  error('ACO tests require LLVM, but LLVM is disabled.')
+elif with_gallium_radeonsi or with_swrast_vk
+  error('The following drivers require LLVM: RadeonSI, SWR, Lavapipe. One of these is enabled, but LLVM is disabled.')
+elif with_gallium_opencl
+  error('The OpenCL "Clover" state tracker requires LLVM, but LLVM is disabled.')
+elif with_clc
+  error('The CLC compiler requires LLVM, but LLVM is disabled.')
+else
+  draw_with_llvm = false
+endif
+```
+
+simplified to:
+```meson
+_llvm = get_option('llvm') \
+  .enable_if(with_amd_vk and with_aco_tests, error_message : 'ACO tests requires LLVM') \
+  .enable_if(with_gallium_radeonsi, error_message : 'RadeonSI requires LLVM') \
+  .enable_if(with_swrast_vk, error_message : 'Vulkan SWRAST requires LLVM') \
+  .enable_if(with_gallium_opencl, error_message : 'The OpenCL Clover state trackers requires LLVM') \
+  .enable_if(with_clc, error_message : 'CLC library requires LLVM')
+
+dep_llvm = dependency(
+  'llvm',
+  version : _llvm_version,
+  modules : llvm_modules,
+  optional_modules : llvm_optional_modules,
+  required : _llvm,
+  static : not _shared_llvm,
+  fallback : ['llvm', 'dep_llvm'],
+  include_type : 'system',
+)
+with_llvm = dep_llvm.found()
+```
+
+## Generated objects can be passed in the `objects:` keyword argument
+
+In previous versions of Meson, generated objects could only be
+passed as sources of a build target.  This was confusing, therefore
+generated objects can now be passed in the `objects:` keyword
+argument as well.
+
+## The project function now supports setting the project license files
+
+This goes together with the license name. The license files can be
+automatically installed via [[meson.install_dependency_manifest]],
+or queried via [[meson.project_license_files]].
+
+## A new core directory option "licensedir" is available
+
+This will install a dependency manifest to the specified directory, if none
+is is explicitly set.
+
+## `sudo meson install` now drops privileges when rebuilding targets
+
+It is common to install projects using sudo, which should not affect build
+outputs but simply install the results. Unfortunately, since the ninja backend
+updates a state file when run, it's not safe to run ninja as root at all.
+
+It has always been possible to carefully build with:
+
+```
+ninja && sudo meson install --no-rebuild
+```
+
+Meson now tries to be extra safe as a general solution. `sudo meson install`
+will attempt to rebuild, but has learned to run `ninja` as the original
+(pre-sudo or pre-doas) user, ensuring that build outputs are generated/compiled
+as non-root.
+
+## `meson install` now supports user-preferred root elevation tools
+
+Previously, when installing a project, if any files could not be installed due
+to insufficient permissions the install process was automatically re-run using
+polkit. Now it prompts to ask whether that is desirable, and checks for
+CLI-based tools such as sudo or opendoas or `$MESON_ROOT_CMD`, first.
+
+Meson will no longer attempt privilege elevation at all, when not running
+interactively.
+
+## Support for reading options from meson.options
+
+Support has been added for reading options from `meson.options` instead of
+`meson_options.txt`. These are equivalent, but not using the `.txt` extension
+for a build file has a few advantages, chief among them many tools and text
+editors expect a file with the `.txt` extension to be plain text files, not
+build scripts.
+
+## Redirect introspection outputs to stderr
+
+`meson introspect` used to disable logging to `stdout` to not interfere with generated json.
+It now redirect outputs to `stderr` to allow printing warnings to the console
+while keeping `stdout` clean for json outputs.
+
+## New "none" backend
+
+The `--backend=none` option has been added, to configure a project that has no
+build rules, only install rules. This avoids depending on ninja.
+
+## compiler.preprocess()
+
+Dependencies keyword argument can now be passed to `compiler.preprocess()` to
+add include directories or compiler arguments.
+
+Generated sources such as custom targets are now allowed too.
+
+## New pybind11 custom dependency
+
+`dependency('pybind11')` works with pkg-config and cmake without any special
+support, but did not handle the `pybind11-config` script.
+
+This is useful because the config-tool will work out of the box when pybind11
+is installed, but the pkg-config and cmake files are shoved into python's
+site-packages, which makes it impossible to use in an out of the box manner.
+
+
+## Allow --reconfigure and --wipe of empty builddir
+
+`meson setup --reconfigure builddir` and `meson setup --wipe builddir` are now
+accepting `builddir/` to be empty or containing a previously failed setup attempt.
+Note that in that case previously passed command line options must be repeated
+as only a successful build saves configured options.
+
+This is useful for example with scripts that always repeat all options,
+`meson setup builddir --wipe -Dfoo=bar` will always work regardless whether
+it is a first invocation or not.
+
+## Allow custom install scripts to run with `--dry-run` option
+
+An new `dry_run` keyword is added to `meson.add_install_script()`
+to allow a custom install script to run when meson is invoked
+with `meson install --dry-run`. 
+
+In dry run mode, the `MESON_INSTALL_DRY_RUN` environment variable
+is set.
