Log Message:
Update to 0.60. From the changelog:

0.60:

Asciidoc:
 * Introduce "compat" option to parse like asciidoc or asciidoctor.

Text (and Markdown):
 * Fix the support of nested lists (GitHub's #131).

Other:
 * Remove the experimental C extension that was never built,
   distributed, tested nor modified since 2007.

XML:
 * Provide a meaningful message when the translators butcher the
   <placeholder> attributes instead of truncating the file.
   (GitHub's #254)

0.59.1:

po4a tool:
 * Really fix --srcdir and --destdir handling (Debian's #960892 again).
   Even with the previous fix, the aptitude package was still broken.

Documentation:
 * Clarify the syntax of -o parameters (GitHub's #233).

Sgml:
 * Sort the attributes. Without this, msgids are randomly fuzzied.
   (Debian's #725931 and Debian's #810988)

0.59:

po4a tool:
 * Fix --srcdir handling (GitHub's #237 and Debian's #960892).
   This bug was breaking the build of several packages, including dpkg.

Addendum:
 * New mode 'eof' to easily add at the end of the file (Debian's #960949).

Documentation:
 * Fix many typos and glitches
 * Start a section about external projects using po4a

Tests:
 * po4a: Add a test for the [po_directory] feature

Overall:
 * Improve the displayed messages, don't translate debug messages.

0.58.1:

Documentation:
 * Document an option of the XML parser (GitHub's #223).
 * Small glitches found during the translations.

Tests:
 * Also ignore 'Project-Id-Version' when diffing PO files (GitHub's #224)
 * asciidoc: reactivate tablecells tests

AsciiDoc:
 * Fix management of images in tables (Github's #226)
 * Tolerate underline length variations in two lines titles (Github's #212)

0.58:

AsciiDoc:
 * Accept numbered list items beginning with any number of dots
   (GitHub's #210)

Markdown:
 * Avoid translating Markdown fenced code block info string (GitHub's #194)
 * List Markdown fenced code block info string as text type (GitHub's #195)
 * Support YAML Front Matter (GitHub's #196). This requires YAML::Tiny.
 * Introduce options yfm_keys and yfm_skip_array to respectively
   specify which YAML keys should be translated, and that the array
   content should not be translated.
 * Work around a bug in YAML::Tiny that quotes numbers (GitHub's #217)
 * Add gettext flag "markdown-text" for relevant entries (GitHub's #208)

Text:
 * Honor the (existing) --neverwrap option to handle every content verbatim.

Texinfo:
 * Add the comments starting with 'TRANSLATORS:' to the po file
   (GitHub's #162)

XHTML:
 * Don't fail nor warn when a closing tag is missing, that's legit in HTML.
   (GitHub's #179)

XML and DocBook:
 * Allow attributes with no value (GitHub's #178).
 * Processing Instructions are handled as inline tags by default, but
   you can change them back to breaking with '-o break-pi' (GitHub's #170)

Yaml:
 * Introduce option to skip array values. (GitHub's #187)

po4a tool:
 * Cleanups and fixups about options' parsing (now tested and documented)
     _
    / \  You may need to upgrage your po4a.conf if you were using
   /_!_\ "unwanted features" (ie, bugs) of the previous implementation.

 * Do not touch source dir when --destdir is provided (Debian #602387)
 * Pass --add-location=file to msgmerge when receiving option porefs.
   (requires gettext >= 0.19 -- June 2014)
 * Option --master-charset sets the charset of the generated POT file.
 * Option --master-language sets the language of the generated POT file.
 * Add support for addendum path in po4a_paths (Debian #823189)
 * Stop pretending that --porefs can control the wrapping of reference
   comments, as the gettext tools used internally always rewrap them.

Scripts:
 * Rename po4aman-display-po to po4a-display-man
 * Rename po4apod-display-po to po4a-display-pod

Core:
 * Use UTF-8 by default (the 20th century is over -- Debian #862460)
   po4a used to prefer ascii unless it proved impossible. But the
   underlying detection would fail, possibly for document containing
   UTF-8 chars composed on printable ascii chars only.
 * Add a --wrap-po option to control how the po file is wrapped, and
   chose between either nicely wrapped files that tend to produce git
   conflicts, or ugly files that are easy to automatically deal with.

Tests:
 * Completely refactor most tests. They are now more reliable and the
   error messages are much more useful to understand the issues.
 * Many bugs to po4a and the core were ironed out in the process.
 * PO files content are now tested too (GitHub's #67)

Documentation:
 * Various cleanups by Golubev Alexander (GitHub's #190 & #191)
