NAME
deb-changelog - dpkg source packages' changelog file format
SYNOPSIS
debian/changelog
DESCRIPTION
Changes in the packaged version of a project are explained in the changelog file debian/changelog. This
includes modifications made in the source package compared to the upstream one as well as other changes
and updates to the package.
The format of the debian/changelog allows the package building tools to discover which version of the
package is being built and find out other release-specific information.
That format is a series of entries like this:
package (version) distributions; metadata
[optional blank line(s), stripped]
* change-details
more-change-details
[blank line(s), included in dpkg-parsechangelog(1) output]
* even-more-change-details
[optional blank line(s), stripped]
-- maintainer-name <email-address> date
package and version are the source package name and version number. version is delimited by parenthesis
U+00028 ‘(’ and U+0029 ‘)’.
distributions lists one or more space-separated distributions where this version should be installed when
it is uploaded; it is copied to the Distribution field in the .changes file. distributions must be
terminated by a semicolon (U+003B ‘;’).
metadata lists zero or more comma-separated keyword=value items. Each keyword can contain only minus and
case insensitive alphanumeric characters, as they need to be mapped to deb822(5) field names. The only
keywords currently supported by dpkg are:
urgency
Its value is used for the Urgency field in the .changes file for the upload.
binary-only
With a yes value, it is used to denote that this changelog entry is for a binary-only non-maintainer
upload (an automatic binary rebuild with the only change being the changelog entry).
The change details may in fact be any series of lines starting with at least two spaces (U+0020 SPACE),
but conventionally each change starts with an asterisk and a separating space and continuation lines are
indented so as to bring them in line with the start of the text above. Blank lines may be used here to
separate groups of changes, if desired.
If this upload resolves bugs recorded in the distribution bug tracking system, they may be automatically
closed on the inclusion of this package into the distribution archive by including the string:
Closes: #nnnnn
in the change details, where #nnnnn is the bug number. The exact Perl regular expression is:
/closes:\s*(?:bug)?\#?\s?\d+(?:,\s*(?:bug)?\#?\s?\d+)*/i
That is, the string should consist of the word closes: followed by a comma-separated list of bug numbers.
Bug numbers may be preceded by the word bug and/or a # sign, as in "Closes: 42, bug#43, #44, bug 45".
The words closes: and bug are not case sensitive. The list of bug numbers may span multiple lines.
This information is conveyed via the Closes field in the .changes file. Where, depending on the archive
maintenance software, all the bug numbers listed might get automatically closed.
The maintainer name and email address used in the changelog should be the details of the person who
prepared this release of the package. They are not necessarily those of the uploader or usual package
maintainer. The information here will be copied to the Changed-By field in the .changes file, and then
later might be used to send an acknowledgment when the upload has been installed in the distribution
archive.
The date has the following format (compatible and with the same semantics of RFC2822 and RFC5322, or what
«date -R» generates):
day-of-week, dd month yyyy hh:mm:ss +zzzz
where:
day-of-week
Is one of: Mon, Tue, Wed, Thu, Fri, Sat, Sun.
dd Is a one- or two-digit day of the month (01-31), where the leading zero is optional, but
conventionally does not get omitted.
month
Is one of: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.
yyyy
Is the four-digit year (e.g. 2010).
hh Is the two-digit hour (00-23).
mm Is the two-digit minutes (00-59).
ss Is the two-digit seconds (00-60).
[+-]zzzz
Is the time zone offset from Coordinated Universal Time (UTC). ‘+’ indicates that the time is ahead
of (i.e., east of) UTC and ‘-’ indicates that the time is behind (i.e., west of) UTC. The first two
digits indicate the hour difference from UTC and the last two digits indicate the number of
additional minutes difference from UTC. The last two digits must be in the range 00-59.
The first “title” line with the package name must start at the left hand margin. The “trailer” line with
the maintainer and date details must be preceded by exactly one space (U+0020 SPACE). The maintainer
details and the date must be separated by exactly two spaces (U+0020 SPACE). Each part of the date can
be separated by one or more spaces (U+0020 SPACE), except after the comma where it can be separated by
zero or more spaces (U+0020 SPACE).
Any line that consists entirely (i.e., no leading whitespace) of # or /* */ style comments or RCS
keywords.
Vim modelines or Emacs local variables, and ancient changelog entries with other formats at the end of
the file should be accepted and preserved on output, but their contents might be otherwise ignored and
parsing stopped at that point.
The entire changelog must be encoded in UTF-8.

EXAMPLES
dpkg (1.17.18) unstable; urgency=low
[ Guillem Jover ]
* Handle empty minimum versions when initializing dependency versions,
as the code is mapping the minimum version 0 to '' to avoid outputting
useless versions. Regression introduced in dpkg 1.17.17. Closes: #764929
[ Updated programs translations ]
* Catalan (Guillem Jover).
[ Updated dselect translations ]
* Catalan (Guillem Jover).
* German (Sven Joachim).
