+ * Update spec.
+ * Use unsigned integer when shifting (Phil Turnbull).
+ Avoids a UBSAN warning which can be triggered when handling a
+ long sequence of backticks.
+ * Avoid memcpy'ing NULL pointers (Phil Turnbull).
+ Avoids a UBSAN warning when link title is empty string.
+ The length of the memcpy is zero so the NULL pointer is not
+ dereferenced but it is still undefined behaviour.
+ * DeMorgan simplification of some tests in emphasis parser.
+ This also brings the code into closer alignment with the wording
+ of the spec (see jgm/CommonMark#467).
+ * Fixed undefined shift in commonmark writer (#211).

+ * latex writer: fix memory overflow (#210).
+ We got an array overflow in enumerated lists nested more than
+ 10 deep with start number =/= 1.
+ This commit also ensures that we don't try to set `enum_` counters
+ that aren't defined by LaTeX (generally up to enumv).
+ Found by google/oss-fuzz:
+ <https://oss-fuzz.com/v2/testcase-detail/5546760854306816>.
+ * Check for NULL pointer in get_link_type (Phil Turnbull).
+ `echo '[](xx:)' | ./build/src/cmark -t latex` gave a
+ segfault.
+ * Move fuzzing dictionary into single file (Phil Turnbull).
+ This allows AFL and libFuzzer to use the same dictionary
+ * Reset bytes after UTF8 proc (Yuki Izumi, #206).
+ * Don't scan past an EOL (Yuki Izumi).
+ The existing negated character classes (`[^…]`) are careful to
+ always include` \x00` in the characters excluded, but these `.`
+ catch-alls can scan right past the terminating NUL placed
+ at the end of the buffer by `_scan_at`. As such, buffer
+ overruns can occur. Also, don't scan past a newline in HTML
+ block end scanners.
+ * Document cases where `get_` functions return `NULL` (#155).
+ E.g. `cmark_node_get_url` on a non-link or image.
+ * Properly handle backslashes in link destinations (#192).
+ Only ascii punctuation characters are escapable, per the spec.
+ * Fixed `cmark_node_get_list_start` to return 0 for bullet lists,
+ as documented (#202).
+ * Use `CMARK_NO_DELIM` for bullet lists (#201).
+ * Fixed code for freeing delimiter stack (#189).
+ * Removed abort outside of conditional (typo).
+ * Removed coercion in error message when aborting from buffer.
+ * Print message to stderr when we abort due to memory demands (#188).
+ * `libcmark.pc`: use `CMAKE_INSTALL_LIBDIR` (#185, Jens Petersen).
+ Needed for multilib distros like Fedora.
+ * Fixed buffer overflow error in `S_parser_feed` (#184).
+ The overflow could occur in the following condition:
+ the buffer ends with `\r` and the next memory address
+ contains `\n`.
+ * Update emphasis parsing for spec change.
+ Strong now goes inside Emph rather than the reverse,
+ when both scopes are possible. The code is much simpler.
+ This also avoids a spec inconsistency that cmark had previously:
+ `***hi***` became Strong (Emph "hi")) but
+ `***hi****` became Emph (Strong "hi")) "*"
+ * Fixes for the LaTeX renderer (#182, Doeme)
+ + Don't double-output the link in latex-rendering.
+ + Prevent ligatures in dashes sensibly when rendering latex.
+ `\-` is a hyphenation, so it doesn't get displayed at all.
+ * Added a test for NULL when freeing `subj->last_delim`.
+ * Cleaned up setting of lower bounds for openers.
+ We now use a much smaller array.
+ * Fix #178, quadratic parsing bug. Add pathological test.
+ * Slight improvement of clarity of logic in emph matching.
+ * Fix "multiple of 3" determination in emph/strong parsing.
+ We need to store the length of the original delimiter run,
+ instead of using the length of the remaining delimiters
+ after some have been subtracted. Test case:
+ `a***b* c*`. Thanks to Raph Levin for reporting.
+ * Correctly initialize chunk in S_process_line (Nick Wellnhofer, #170).
+ The `alloc` member wasn't initialized. This also allows to add an
+ assertion in `chunk_rtrim` which doesn't work for alloced chunks.
+ * Added 'make newbench'.
+ * `scanners.c` generated with re2c 0.16 (68K smaller!).
+ * `scanners.re` - fixed warnings; use `*` for fallback.
+ * Fixed some warnings in `scanners.re`.
+ * Update CaseFolding to latest (Kevin Wojniak, #168).
+ * Allow balanced nested parens in link destinations (Yuki Izumi, #166)
+ * Allocate enough bytes for backticks array.
+ * Inlines: Ensure that the delimiter stack is freed in subject.
+ * Fixed pathological cases with backtick code spans:
+
+ - Removed recursion in scan_to_closing_backticks
+ - Added an array of pointers to potential backtick closers
+ to subject
+ - This array is used to avoid traversing the subject again
+ when we've already seen all the potential backtick closers.
+ - Added a max bound of 1000 for backtick code span delimiters.
+ - This helps with pathological cases like:
+
+ x
+ x `
+ x ``
+ x ```
+ x ````
+ ...
+
+ - Added pathological test case.
+
+ Thanks to Martin Mitáš for identifying the problem and for
+ discussion of solutions.
+ * Remove redundant cmake_minimum_required (#163, @kainjow).
+ * Make shared and static libraries optional (Azamat H. Hackimov).
+ Now you can enable/disable compilation and installation targets for
+ shared and static libraries via `-DCMARK_SHARED=ON/OFF` and
+ `-DCMARK_STATIC=ON/OFF`.
+ * Added support for built-in `${LIB_SUFFIX}` feature (Azamat H.
+ Hackimov). Replaced `${LIB_INSTALL_DIR}` option with built-in
+ `${LIB_SUFFIX}` for installing for 32/64-bit systems. Normally,
+ CMake will set `${LIB_SUFFIX}` automatically for required enviroment.
+ If you have any issues with it, you can override this option with
+ `-DLIB_SUFFIX=64` or `-DLIB_SUFFIX=""` during configuration.
+ * Add Makefile target and harness to fuzz with libFuzzer (Phil Turnbull).
+ This can be run locally with `make libFuzzer` but the harness will be
+ integrated into oss-fuzz for large-scale fuzzing.
+ * Makefile: use warnings with re2c.
+ * README: Add link to Python wrapper, prettify languages list
+ (Pavlo Kpyshin).
+ * README: Add link to cmark-scala (Tim Nieradzik, #196)
+
[0.27.1]
* Set policy for CMP0063 to avoid a warning (#162).
