v0.7.4

Fixes

• Return the input as the preamble, instead of an empty string, when a patch has no files (#46)

v0.7.3

Improvements

• Accept invalid (according to RFC 5322) email addresses in From: lines of mail-formatted patches (#44)
• More closely follow Git's logic when parsing identities with ParsePatchIdentity (#44)
  • Extract email addresses even when they do not appear in angle brackets
  • Consider content that appears after the email address as part of the name
  • Unquote escaped characters in quoted strings and RFC 5322 comments
  • Normalize runs of white space in names to single space characters

v0.7.2

Improvements

• Accept more inputs in ParsePatchIdentity (#42)
  • Allow identity strings with empty email address (must still include <> markers)
  • When an identity contains only an email address, also use it to set the Name field

v0.7.1

Fixes

• Fix error parsing mode lines with trailing whitespace (#38)

v0.7.0

API Breaks

• Remove the Applier type and replace it with TextApplier and BinaryApplier. This does not impact clients that only use the top-level Apply function (#32).

Improvements

• Add an option to control which content is removed from subject lines when parsing the headers of mail-formatted patches (#36)
• Simplify internal logic for patch header parsing (#34)
• Run tests and lint checks with Go 1.19 (#35)

v0.6.1

Fixes

• Fix out-of-bounds panic in timestamp parsing (#28)
• Fix panic when parsing certain invalid text fragments (#29)
• Return an error when parsing text fragments that contain only context lines (#29)
• Use ioutil to retain compatibility with Go versions prior to 1.16 (#31)

v0.6.0

API Breaks

• Improve the behavior of the LineReaderAt interface when the final line does not have a newline character. This change is only relevant for clients that define LineReaderAt implementations and should not affect most users of the library. If you use a custom LineReaderAt implementation, please review the documentation and update your implementation to avoid errors (#27).

Fixes

• Fix apply errors (unexpected EOF) with files that are multiples of 1024 bytes and have no final newline (#27).

v0.5.2

Improvements

• Decode quoted-printable UTF-8 subjects when parsing mail-formatted patch headers (#25)

v0.5.1

Improvements

• Relax requirements for mail-formatted patch headers (#20)

Fixes

• Fix parsing for file names with spaces (#24)

v0.5.0

Improvements

• Remove email decoration ([PATCH], re:, etc) from patch titles in ParsePatchHeader (#17). Any content removed in this way is stored in the SubjectPrefix field of PatchHeader.
• Remove email trailers (content after a --- line) from patch bodies in ParsePatchHeader (#19). Any content removed in this way is stored in the BodyAppendix field of PatchHeader.
