## 3.4.7: 2023-08-17 {#version-3-4-7}

### Fixes

  * po: Fixed a parser bug that it may add a `fuzzy` flag to non-fuzzy
    entry with `ignore_fuzzy: true`.

    Example PO:

    ```po
    #, fuzzy
    #: file.rb:10
    msgid "hello"
    msgstr "bonjour"

    msgid "non-fuzzy"
    msgstr "non-fuzzy string"
	```

    `hello` entry is ignored because `ignore_fuzzy` is `true`. The
    `fuzzy` flag in the `hello` entry is added to `non-fuzzy` entry.

    http://www.gnu.org/software/gettext/manual/html_node/PO-Files.html
    for details of comment type.
  * [POEntry] Checked if specified type is valid in #type=.
  * [PoParser][MO] Concatenated msgctxt, msgid, msgid\_plural to
    "#{msgctxt}\004#{msgid}\000"{msgid\_plural}" by MO instead of
    PoParser. PoData and MO treat a concatenated string as msgid, but
    PO doesn't.
  * [PoParser] Parsed each type comment from whole comment.

### Changes

  * Rename some classes and methods.
    * PoMessage to PoEntry. This isn't "message" but "entry".
      (See http://www.gnu.org/software/gettext/manual/gettext.html#PO-Files)
    * PoMessages#== to POEntry#mergeable?.
    * PoMessages#to\_po\_str to POEntry#to\_s.
    * PoMessages#sources(sources=) to POEntry#references(references=)
    * MoFile to MO. For backword compatible, MoFile can be used now.
    * PoParser to POParser. For backword compatible, PoParser can be used now.
  * Raised no error when POEntry doesn't have references.
    It is useful for no references in .PO file.
