Version 6.1.2
=============

Code Fixes
----------

* Fix for low-severity CVE-2026-23868 affecting gifponge, giftool, and gifbuild,
  but not the core library - library clients need not be alarned.

Version 6.1.1
=============

This release bumps the major version, but only one entry point -
EGifSpew() - has changed signature and behavior (in order to be able
to pass out a detailed error code). The internal error
codes in the E_GIF_ERR series have changed value so none of them
collides with GIF_ERROR.

This code has been systematically audited and hardened wuth
ChatGPT-5.2. The only library fixes reported by users or found by
robot were for some memory leaks that could only triggered by severely
malformed GIFs. Other bugs are edge-case failures in the CLI tools.

The gif2rbg CLI tool has been moved to the "obsolete" bin, because its
only deployment case in 2026 is as a piñata at fuzzer parties.

Warning: the CLI tools in the obsolete category will soon be removed
from the distribution entirely. The maintainer is tired of fielding
junk bugs filed against them by would-be coup-counters who found yet
another edge case, and the rest of the world doesn't need noisy CVEs
that aren't actually DoS or security issues for giflib clients.

Tests
-----

Test suite now emits TAP (Test Anything Protocol).

Upstream changes:
## 2025 03 11
    - The options --want-call-parens and --nowant-call-parens were accidentally
      being skipped in version 20250214. This has been fixed.
    - Fixed git NetBSD#32, a tokenization error with message "hit EOF seeking end of
      quote/pattern" for a function call without paren or arg before a
      ternary operator.
    - A new option --dump-similar-keys will dump hash keys which are
      similar but slightly different to standard output and then exit.
      A related option --warn-similar-keys will report keys with are similar
      to the error output while formatting. Both of these can be controlled
      by parameters which are described in the input manual.
    - A new option --dump-hash-keys will dump all hash keys found by
      perltidy to standard output.
    - The output table for --dump-block-summary has an additional field.
      It is an alternate McCabe complexity count which is the same as
      the previous count except for subs. For subs, the complexity number
      is reduced by the values for any contained anonymous subs.
    - Fix git #181, remove continuation indentation from closing brace
      of an anonymous sub which terminates an input stream.
## 2025 02 14
    - A new option --keep-old-blank-lines-exceptions=s, or --kblx=s,
      allows selected blank lines to be ignored when an input stream
      is read. The parameter s is used to select the blank lines to
      be ignored. This option provides an inverse to other blank line
      parameters. The manual has details. See discussion git #180.
    - A new option --warn-unused-keys, or -wuk, has been added which will
      produce warnings for unused hash keys during formatting. This is similar
      to --dump-unused-keys, which just exits and does not continue formatting.
      A related new parameter --warn-unused-keys-cutoff=N provides control
      over a filter which prevents warnings for keys which appear to be
      members of large hashes used to communicate with external packages.
      The manual has details.  See also git NetBSD#177.
    - A new option --pack-opening-types='->' has been added to provide more
      control over breaks of method call chains.  It tells perltidy not to
      break at every method call when a chain of calls spans multiple lines.
      This was the behavior in versions prior to 20250105. The default
      starting with 20250105 is to break at each call of a method call chain
      which spans multiple lines. The manual has details. See also git NetBSD#171.

# changes

Added

    Add YYJSON_READ_ALLOW_BOM flag to allow UTF-8 BOM.
    Add YYJSON_WRITE_FP_TO_FLOAT flag to write real numbers using single-precison.
    Add YYJSON_WRITE_FP_TO_FIXED(prec) flag to write real numbers using fix-point notation.
    Add set_fp_to_float() and set_fp_to_fixed() functions to control the output format of a specific number.
    Add set_str_noesc() function to skip escaping for a specific string during writing.
    Add yyjson_incr_read(), yyjson_incr_new(), yyjson_incr_free() functions for incremental DOM reading.

Changed

    Rewrite the floating-point number to string functions with a new fast path.
    When comments are allowed, return UNEXPECTED_END instead of INVALID_COMMENT for unclosed comments.
    Truncated escape sequences now report the error position at the sequence start rather than the end.

# upstream changes (since 2.9.2)

## keychain 2.9.5 (16 May 2025)

This is a bugfix release.

* Hardening checks were failing on Android and some MacOS environments. Make them
  more compatible and lower to warnings instead of aborting the script, until
  they have been tested in more environments.
  ([NetBSD#177](danielrobbins/keychain#177))

* Fixed issues with indentation of `note()`, `warn()`, `mesg()`.

* Convert `SSH_AUTH_SOCK in pidfile is invalid; ignoring it` into a debug message,
  as this is normal when rebooting your system so is not really useful to show
  typically. ([NetBSD#176](danielrobbins/keychain#176))

## keychain 2.9.4 (14 May 2025)

This is a minor bugfix release.

* Fix minor regression which allowed some warnings to display with `--quiet`.
([NetBSD#175](danielrobbins/keychain#175))

* "Cannot find separate public key" turned into a `note()` rather than `warn()`,
  along with several other non-critical notices. `note()` can be suppressed with
  `--quiet`, unlike `warn()`. ([NetBSD#157](danielrobbins/keychain#157))

* Minor improvement when wiping GnuPG keys with `--wipe` option so keychain output
  is more understandable when gpg-agent is not running.

## keychain 2.9.3 (14 May 2025)

This is a security and bug fix release. Many thanks to those who have reported
issues to GitHub, send in pull requests, and tested out fixes. 2.9.3 includes
the following updates:

* The `--quick` option logic had several bugs which have been resolved. Thanks
  to Filipe Fernandes (@ffernand) for reporting the issue and for assistance
  testing fixes. ([NetBSD#167](danielrobbins/keychain#167))

* Fix keychain `--query` exit code when no pidfile exists.
  ([NetBSD#171](danielrobbins/keychain#171))

* `--systemd` option should now be fixed.
  ([[NetBSD#168](danielrobbins/keychain#168)])

* Harden keychain so the use of the `--dir` and `--absolute` options cannot be
  used to instruct keychain to write pidfiles into insecure areas.
  ([NetBSD#174](danielrobbins/keychain#174))

  Prior to this release, it was possible to use these options in combination
  with bad (empty) default umask to write pidfiles into a public area on disk
  where they were writable by other users. In the worst case, this could allow
  arbitrary execution of the contents of the malicious pidfile by keychain.

  This hardening now makes it difficult for a user to configure their keychain
  in a way that would allow this to happen. Note that if you are not using the
  `--dir` or `--absolute` options, keychain will use the `$HOME/.keychain`
  directory by default, which is typically under the full control of the
  current user and thus not exploitable.

  The hardening changes include:

  * Setting a global restrictive `umask` in the script.
  * Remove pidfiles before redirecting data to them to ensure they are created
    with restrictive permissions from the `umask`.
  * Check the keychain pidfile directory to ensure it is owned by the current
    user, and only the current user can access it (mode 700). If not, abort
    with an informative error message.
  * Check any existing pidfiles prior to use to make sure they are owned by the
    current user, and only the current user can access them. If not, abort with
    an informative error message.

Upstream changes:
20250809.0 Sat Aug 9 2025
 - Tests are good in dev version. Releasing to stable.
20250715.0_01 Tue Jul 15 2025
 - NetBSD#172 - Reduce delays in detecting child exit
 - NetBSD#174 - Add quickstart section at the top of the docs
 - NetBSD#177 - Retry _read() on EINTR, instead of losing pipe contents.
 - In test suite, work around bug in NetBSD 10.

    Added support for free threaded CPython (3.14t+ only). (NetBSD#178)
    Note that the free-threaded build does not yet support building
    extensions with the limited API, so you must set py_limited_api=False
    when building extensions for the free-threaded build. CPython
    3.13t is not currently supported due to differences in sync
    primitive behavior from 3.14t that result in segfaults.

    Added support for Python 3.14. (NetBSD#177)

    Dropped support for Python 3.8.

Changed templating engine

Matugen now finally uses its own custom written templating engine with using colors as the main priority.
You can import colors from json as well.

## [0.9.4] - 2026-02-03

### Major: Full Windows Support

This release adds **full native Windows support**. libfyaml now builds and runs natively on Windows with MSVC, clang-cl, and Clang compilers.

**Native Windows builds:**
- Full support for building on Windows using MSVC, clang-cl, or GCC
- Works with Visual Studio, VSCode, and other Windows development tools
- All tests pass on Windows

**Cross-compilation from Linux:**
- Support for msvc-wine to install MSVC redistributables on Linux
- Compile using `cl.exe` via Wine
- Compile using `clang-cl` without Wine
- Compile using Clang cross-compilation triplet

### Major: Comment Support Now Stable

Comment parsing and emission has been moved out of experimental status. Comments can now be reliably preserved and manipulated through the API.

### Added

- `fy_node_set_style()`: Set the style of a node (block, flow, plain, etc.) - Fixes NetBSD#78
- `fy_token_set_comment()`: Attach comments to tokens programmatically
- `fy_event_to_string()`: Convert events to string representation
- `fy_diag_get_collect_errors()`: Query if error collection is enabled
- `fy_atom_lines_containing()`: Get lines containing an atom (for diagnostics)
- `fy_memstream`: Portable `open_memstream` alternative for cross-platform support
- CMake-based CI workflow with improved matrix coverage
- Emscripten platform detection for `endian.h`

### Changed

- libclang now defaults to OFF (will be enabled when reflection features are ready)
- Document start token is now preserved (may contain comments)
- Walk methods now handle error paths more systematically
- Removed non-existent experimental function declarations from `libfyaml.h`

### Fixed

- **#193**: Token creation now properly clears memory to avoid undefined behavior on invalid input
- **#186**: Reference loop nesting now respected when checking link validity
- **#185**: Fixed crash when setting document root to NULL; also fixed input size clamping for corrupted input
- **#184**: Walk memory leak fix with improved debugging infrastructure
- **#183, #191**: Error out early on `FYECF_EXTENDED_CFG` with helper emit methods (prevents crash)
- **#182**: Walk expression unref bug fix with debug infrastructure
- **#181**: Walk double-free on node delete
- **NetBSD#178, NetBSD#177**: Walk methods now handle error paths systematically (recursive alias resolution)
- **NetBSD#176**: Off-by-one error in `fy_accel_grow`
- **NetBSD#175**: Parser crash on corrupted UTF-8 at end of file
- **NetBSD#174**: Superfluous document end marker with explicit version/tag directives
- **NetBSD#173, NetBSD#172**: Depth limit for node copy (prevents stack overflow under fuzzing)
- **NetBSD#143**: Document root now correctly marked as attached
- Emit state now properly reset at end of document (fixes multi-document stream markers)
- Flow quoting error on ANY style (test was backwards)
- Empty file `fdopen` issue on some platforms
- Empty stream `realloc(0)` undefined behavior
- Removed jarring notice when alias is declared multiple times (valid YAML)

### Platform Support

**Supported platforms**: Linux, macOS, FreeBSD, OpenBSD, NetBSD, and **Windows**.

**Windows-specific:**
- Full native MSVC support (32-bit and 64-bit)
- clang-cl and Clang cross-compilation support
- msvc-wine support for Linux-based Windows cross-compilation
- Proper CRLF (DOS line ending) handling
- Fixed 32-bit MSVC intrinsics (`_BitScanForward64`, `_BitScanReverse64`, `__popcnt64`)

**Portability fixes:**
- Fixed void pointer arithmetic (GCC extension) for strict C compliance
- Fixed GCC ternary operator extension (`x ? : y` -> `x ? x : y`)
- Fixed `\e` escape sequence (GCC/clang extension) -> `\x1b`
- Fixed enum comparison warnings across platforms
- Align mremap initial size to page boundary (fixes BSD crashes)

**macOS:**
- Fixed ASAN support (requires `-fsanitize=address` at link time)
- Added extra ASAN flags for Apple's clang (alloca poisoning disabled)

**CI/Build:**
- New CMake-based GitHub Actions workflow
- Improved build matrix coverage
- Fixed distcheck breakage

### Internal

- Walk expression debug infrastructure for easier debugging
- Portable `fy_memstream` wrapper for `open_memstream`
- Use `fy_align_alloc/free` wrappers in allocator
- Fixed allocator `get_caps` return type (enum, not int)
- Atomic counter function instead of macro
- General warning cleanup pass

### Statistics

- 58 commits since v0.9.3
- 18 bug fix issues closed
- Full Windows platform support added
