We aim to follow roughly a time-based release schedule. The roadmap describes likely focus and goals for current and upcoming release cycles, but these may change in the interest of keeping releases moving or meeting areas of user and developer interest.
Estimated release: Late April
Goals & Focus:
- Adding getrandom/getentropy functions
- Support for
malloc
replacement. - Using stdio buffer provided to
setvbuf
- General stdio cleanup and internal consistency fixes
- Linux uapi updates
- NOMMU/FDPIC improvements
- Merging further improvements associated with new internal lock implementation
- Complex trig/hyperbolic function basic correctness fixes
Estimated release: Early June
Goals & Focus:
- Locale support polishing:
- Handling for
MON_5
/ABMON_5
translation ambiguity ("May") LC_NUMERIC
,LC_MONETARY
, andLC_COLLATE
functionality
- Handling for
- Resolver support for non-ASCII domains (IDN)
- Dynamic linker improvements:
- Dependency ordering of dynamic-linked constructors
- Resolving recursive
dlopen
locking issues - Code cleanup & deduplication
- Adding
GLOB_TILDE
to glob implementation - UB-correctness fixes including string functions and stdio
- Merging riscv port
- IEEE quad math correctness
- Complex math correctness Complex math correctness
- Enhanced LSB/glibc ABI-compat, especially fortify
__*_chk
symbols - Remapping of glibc-ABI-incompatible symbols (regexec, etc.) by dynamic linker
- New
getlogin[_r]
with lookup via controlling tty - Possible non-stub utmp backends
- ARM Cortex-M FDPIC ABI
- Resolving GCC symbol-versioning incompatibility issue - see http://www.openwall.com/lists/musl/2015/05/10/1
- Message translation support for dynamic linker
The following tentative goals for what would constitute "musl 1.2.0" have been established. There is no projected release date for 1.2.0 at this time.
- Cleanup & build system - DONE
- Deduplication and asm-reduction of atomic operations
- Deduplication of bits headers for archs
- Support for out-of-tree builds
- Improved locale and multilingual support
LC_COLLATE
support for collation orders other than simple codepoint order- Support for
LC_MONETARY
andLC_NUMERIC
properties. - IDN support in DNS resolver
- Character data aligned with current Unicode at time of release
- Porting
- Aarch64 (64-bit ARM) port - DONE
- RISC-V (32- and 64-bit) ports
- Promoting existing experimental ports up from experimental status
- Documentation
- Bringing existing documentation into alignment with changes made since 1.0.0
- Documenting new and non-obsolescent extensions in detail
- Adapting text from wiki and other sources on properties of the implementation relevant to programmers and end users
- Third-party projects
- Non-glibc-based nscd-protocol backend for LDAP (and perhaps NIS)
- Locale data and libc message translations
- External header-file-only fortify library providing
_FORTIFY_SOURCE
feature - DONE - Support for Windows targets via Midipix (http://www.midipix.org)
