Changelog: ========= - Added the max_depth decoder parameter to limit the maximum allowed nesting level of containers, with a default value of 400 levels (CVE-2026-26209) - Changed the default read_size from 4096 to 1 for backwards compatibility. The buffered reads introduced in 5.8.0 could cause issues when code needs to access the stream position after decoding. Users can opt-in to faster decoding by passing read_size=4096 when they don't need to access the stream directly after decoding. Added a direct read path for read_size=1 to avoid buffer management overhead. - Fixed C encoder not respecting string referencing when encoding string-type datetimes (tag 0) - Fixed a missed check for an exception in the C implementation of CBOREncoder.encode_shared() - Fixed two reference/memory leaks in the C extension's long string decoder - Fixed C decoder ignoring the str_errors setting when decoding strings, and improved string decoding performance by using stack allocation for small strings and eliminating unnecessary conditionals. Benchmarks show 9-17% faster deserialization. Signed-off-by: Wang Mingyu <wangmy@fujitsu.com> Signed-off-by: Khem Raj <khem.raj@oss.qualcomm.com>
