0.3.47 [2026-02-05]

Security

• The possibility of a stack exhaustion denial of service attack when parsing RFC 2822 has been eliminated. Previously, it was possible to craft input that would cause unbounded recursion. Now, the depth of the recursion is tracked, causing an error to be returned if it exceeds a reasonable limit.

  This attack vector requires parsing user-provided input, with any type, using the RFC 2822 format.

Compatibility

• Attempting to format a value with a well-known format (i.e. RFC 3339, RFC 2822, or ISO 8601) will error at compile time if the type being formatted does not provide sufficient information. This would previously fail at runtime. Similarly, attempting to format a value with ISO 8601 that is only configured for parsing (i.e. Iso8601::PARSING) will error at compile time.

Added

• Builder methods for format description modifiers, eliminating the need for verbose initialization when done manually.
• date!(2026-W01-2) is now supported. Previously, a space was required between W and 01.
• [end] now has a trailing_input modifier which can either be prohibit (the default) or discard. When it is discard, all remaining input is ignored. Note that if there are components after [end], they will still attempt to be parsed, likely resulting in an error.

Changed

• More performance gains when parsing.

Fixed

• If manually formatting a value, the number of bytes written was one short for some components. This has been fixed such that the number of bytes written is always correct.
• The possibility of integer overflow when parsing an owned format description has been effectively eliminated. This would previously wrap when overflow checks were disabled. Instead of storing the depth as u8, it is stored as u32. This would require multiple gigabytes of nested input to overflow, at which point we've got other problems and trivial mitigations are available by downstream users.
