Deprecation notice
Built-in support for the HTTP and Redis protocols will be removed in the next non-bug-fix ccache version. Use the remote storage helper mechanism (added in ccache 4.13) for HTTP/Redis storage instead.

Removed functionality
- Removed the cpp_extension (CCACHE_EXTENSION) configuration option since ccache now processes preprocessor output directly in memory instead of using intermediate files. [contributed by Joel Rosdahl]

New features and improvements
- Added support for the QCC (QNX) compiler. [contributed by Joy Wang]
- Added limited support for caching SARIF diagnostics: -fdiagnostics-format=sarif-stderr and -fdiagnostics-{add,set}-output=sarif:file=… for GCC, /experimental:log for MSVC. [contributed by Joel Rosdahl, Karl Fessel and Leander Schulten]
- Added automatic depend mode for NVCC on Windows. [contributed by Xing Xiwen]
- Added support for @layout=local in the file storage backend, allowing a copy or read-only mount of a local cache to be used as remote storage. [contributed by Joel Rosdahl]
- Extended the remote storage helper protocol with an exists operation, avoiding transfer of already stored values in reshare mode, and an info operation for reporting the helper’s identity and diagnostics. [contributed by Joel Rosdahl]
- Added a --dry-run option for previewing cleanup, eviction and directory trimming operations without removing files. [contributed by Joel Rosdahl]
- Added support for rewriting absolute profile data file paths to relative, improving cache sharing between different directory trees. [contributed by GitHub user markyang92]
- Added support for reflinking .dwo files when file cloning is enabled. [contributed by Fabian Parzefall]

- Added support for -Wp, options with multiple macro definitions. [contributed by GitHub user subotac]
- Ccache now hashes the contents of Clang module files specified with -fmodule-file=, preventing false cache hits when a module changes. [contributed by GitHub user RedNicStone]
- Cleanup and eviction operations now print the amount of data and number of files removed. [contributed by Joel Rosdahl]
- Increased the maximum number of raw files stored in a cached result to 256. [contributed by Joel Rosdahl]

- Fixed PCH invalidation when the MSVC toolset is updated. [contributed by Philipp Kolberg]
- Fixed base_dir path rewriting when using MSVC’s /Yc option: paths are no longer rewritten to relative when creating a precompiled header, since MSVC then does not like relative paths for the /Yc and /FI arguments. [contributed by Joel Rosdahl]
- Fixed handling of a directory-less path to the MSVC /FI option. [contributed by Joel Rosdahl]
- Added support for -fsanitize-ignorelist (which replaced -fsanitize-blacklist in Clang 13). [contributed by Joel Rosdahl]

- Fixed install.sh to correctly use sysconfdir and other configuration variables from the Makefile. [contributed by Joel Rosdahl]

Build improvements
- Changed cmake/FindCppHttplib.cmake to use settings from the system’s CMake config if available, supporting systems where cpp-httplib is not provided as a header-only library. [contributed by Jiri Slaby]

New deliverables
- Added tar.gz archives for Linux binary releases.
[contributed by Joel Rosdahl]

- Fixed mktemp(1) calls in build scripts to pass a template argument for portability to macOS/BSD. [contributed by Joel Rosdahl]

Upgrade notes:
- A C++20-capable compiler is now required to build ccache from source. Minimum supported compiler versions are GCC 10, Clang 12 and Apple Clang 10.
- Caching MSVC (cl.exe) compilations is now officially supported.

New deliverables:
- Added Linux binary releases statically linked with musl. (contributed by Joel Rosdahl)

Removed deliverables:
- Discontinued 32-bit Windows binary releases. (contributed by Joel Rosdahl)

New features and improvements:
- Added support for remote storage helpers: long-lived local helper processes spawned on demand for communicating with remote storage servers. Storage helpers allow support for new storage protocols to be developed and released independently of ccache. Built-in support for HTTP and Redis will likely be removed in a future release. (contributed by Joel Rosdahl)
- Added support for directory-specific configuration files. Ccache now looks for a ccache.conf file in the current working directory and its parent directories, enabling per-project configuration without modifying the user’s cache-specific config file. (contributed by Joel Rosdahl)
- Added msvc_utf8 config option to allow disabling /utf-8 for MSVC when using the fallback method of parsing preprocessed output. (contributed by Max Winkler)
- Added support for caching distributed ThinLTO for Clang. (contributed by GitHub user zcfh)
- Added support for caching MSVC /sourceDependencies file. (contributed by Joel Rosdahl)
- Added handling of Apple Clang’s -index-unit-output-path option. (contributed by Joel Rosdahl)
- Improved compiler detection on macOS by resolving the actual compiler via $DEVELOPER_DIR or xcode-select when /usr/bin/clang(++) shims that redirect to different compilers are used. (contributed by Joel Rosdahl)
- Added support for rewriting -fcoverage-compilation-dir and -fcoverage-prefix-map absolute paths (similar to existing base_dir rewriting). (contributed by Evgeniy Isaev)
- Added support for rewriting absolute paths in -fsanitize-blacklist option arguments. (contributed by Diego Alonso)
- Added support for multi-line configuration values. (contributed by Joel Rosdahl)
- Improved file copy performance by using copy_file_range(2) when available. (contributed by Oleg Sidorkin)
- Added h, m and ms as accepted time unit suffixes for --evict-older-than (in addition to the existing d and s). (contributed by Joel Rosdahl)
- Merged --recompress-threads and --trim-recompress-threads options into --threads. The old options are still accepted for backward compatibility. (contributed by Joel Rosdahl)
- Improved performance of -x/--show-compression and -X/--recompress by using threads in parallel. (contributed by Joel Rosdahl)
- Added logging of errors and file size changes when recompressing cache files. (contributed by Joel Rosdahl)

Bug fixes:
- Fixed use of monotonic clock for spin locks in the inode cache code. (contributed by Joel Rosdahl)

Build improvements:
- Fixed conditional enabling of the assembler language in CMake to avoid enabling both ASM and ASM_MASM on the same platform. (contributed by Steffen Winter)
- Fixed inclusion of config.h to only apply to C and C++ compilation units, not assembler files. This avoids a problem when building with Clang on Windows. (contributed by Joel Rosdahl)
- Disabled legacy ZSTD support when compiling ZSTD from source to avoid -Wmaybe-uninitialized warnings. (contributed by Joel Rosdahl)
- Removed check for (on POSIX) mandatory spawn.h header. (contributed by Joel Rosdahl)

Documentation improvements:
- Added generation of documentation in Markdown format. (contributed by Joel Rosdahl)

Test improvements:
- Added a basic integration test suite for MSVC. (contributed by Joel Rosdahl)
- Added an integration test for --serialize-diagnostics. (contributed by Joel Rosdahl)
- Added support for Valkey in the remote_redis test suite. (contributed by Joel Rosdahl)
- Fixed -march=native test to work reliably on hybrid CPU systems. (contributed by Joel Rosdahl)

[contributed by Clemens Wasser, Thomas Ferrand and Silver Zachara]

- Added support for the MSVC `/Tc<path>` and `/Tp<path>` options (specifying source code type).
[contributed by Joel Rosdahl]

- Added an experimental inode cache implementation for Windows. This speeds up ccache a lot when many headers are included, both for cache hits and cache misses.

> NOTE:
> This feature is currently disabled by default, but interested Windows users are encouraged to try it out by setting [inode_cache = true](https://ccache.dev/manual/4.10.html#config_inode_cache).

[contributed by Raihaan Shouhell]

- Use `posix_spawn(3)` for executing compiler check commands.
[contributed by Brendan Shanks]

- The [prefix_command](https://ccache.dev/manual/4.10.html#config_prefix_command) and [prefix_command_cpp](https://ccache.dev/manual/4.10.html#config_prefix_command_cpp) configuration options now allow any prefix, not only programs that exist in `PATH`. This means that prefix_command now can be a program with arguments.
[contributed by Joel Rosdahl]

- Added a new `incbin` [sloppiness](https://ccache.dev/manual/4.10.html#config_sloppiness) value for ignoring presence of `.incbin` directives in the source code.
[contributed by Raihaan Shouhell]

- Added a `--print-log-stats` option that prints a machine-parsable variant of `--show-log-stats`.
[contributed Kaspar Schleiser]

[contributed by an anonymous user]

- The “apparent real path” of the object file is now added to the input hash when using `-fprofile-arcs` to avoid false positive hits in some scenarios.
[contributed by Joel Rosdahl]

- When generating profiling information, [run_second_cpp](https://ccache.dev/manual/4.10.html#config_) is now forced to true so that the coverage report won’t refer to a temporary preprocessed file.
[contributed by Joel Rosdahl]

Build impro

Bug fixes
- Improved detection of bad remote storage URLs gracefully. This also fixes crashes seen in ccache’s own test suite.
[contributed by Joel Rosdahl]

- Made caching completely disabled when modification of a source or include file is detected during ccache invocation. Previously this was only done for the direct mode.
[contributed by Joel Rosdahl]
