OTR allows you to have private conversations over IM by providing:
- Encryption
- No one else can read your instant messages.
- Authentication
- You are assured the correspondent is who you think it is.
- Deniability
- The messages you send do not have digital signatures that are
checkable by a third party.  Anyone can forge messages after a
conversation to make them look like they came from you.  However,
during a conversation, your correspondent is assured the messages
they see are authentic and unmodified.
- Perfect forward secrecy
- If you lose control of your private keys, no previous conversation
is compromised.
This package contains the header files and static libraries needed to
develop applications using libotr.

libotr (4.1.1-3) unstable; urgency=medium
[ Antoine Beaupré ]
* Team upload.
* fix Vcs-* URLs to point at salsa
* set package to Multi-Arch: same as per QA
* bump dh compat to 11, drop deps on dh-autoreconf and autotools-dev
* bump policy to 4.1.2, no change
* fix minor lintian warnings
[ Andreas Metzler ]
* B-d on libgcrypt20-dev instead of (dummy transition package)
libgcrypt11-dev. (Closes: #864093)
2016-08-14 - intrigeri <>
libotr (4.1.1-2) unstable; urgency=medium
* New Debian-specific patch: suggest pidgin-otr to Debian and Ubuntu users
who have no OTR plugin, but whose communication peer requests
an OTR conversation to. (Closes: #830796)
* Declare compliance with Standards-Version 3.9.8.
2016-03-10 - intrigeri <>
libotr (4.1.1-1) unstable; urgency=medium
* New upstream release.
* Update upstream OpenPGP signing key.
* Drop previously cherry-picked
0002-Test-Add-new-test-suite-in-tests.patch: it is part
of the new upstream release.
* Declare compliance with Standards-Version 3.9.7 (no change required).
* Update upstream copyright years.
2016-01-15 - intrigeri <>
libotr (4.1.0-7) unstable; urgency=medium
* Bump debhelper compat level to 9, accordingly bump
the versioned build-dependency.
* debian/*install: adjust paths for multiarch.
* Revert "Don't run the test suite on Hurd: it depends on PATH_MAX":
the failure happens during the build, not when running the tests.
* Revert "Don't run the test suite on kfreebsd-*: the test suite
utilities depend on epoll, and fail to build on kfreebsd.":
the failure happens during the build, not when running the tests.
* Disable the test suite on ppc64: it's brittle there too.
2016-01-14 - intrigeri <>
libotr (4.1.0-6) unstable; urgency=low
* Disable the test suite on:
- hurd: it depends on PATH_MAX
- kfreebsd-*: it depends on epoll
- s390x: it's flaky
2016-01-14 - intrigeri <>
libotr (4.1.0-5) unstable; urgency=low
* Disable the test suite for architectures on which
it is not robust… for real, this time.
2016-01-14 - intrigeri <>
libotr (4.1.0-4) unstable; urgency=low
* Disable the test suite for architectures on which it is not robust:
hppa, mips, mipsel, powerpc, ppc64el.
2016-01-12 - intrigeri <>
libotr (4.1.0-3) unstable; urgency=medium
[ Ximin Luo ]
* hand over package to pkg-privacy team
[ intrigeri ]
* Update debian/copyright: bump copyright years, fix licenses version,
and generally be more precise.
* debian/rules: separate targets with an empty line, for better clarity.
* 0002-Test-Add-new-test-suite-in-tests.patch: cherry-pick new upstream
test suite.
* debian/rules: make test suite shell scripts executable before running them.
* 0003-Disable-tests-that-fail-because-we-disable-the-API-v.patch: disable
the tests that fail because we disable the API version check at runtime.
* debian/copyright: add information about the upstream test suite.
2014-11-01 - intrigeri <>
libotr (4.1.0-2) unstable; urgency=medium
* New patch:
Do not error out when an application is run against an older libotr
than the one it was built against: given libotr 4.1 is API- and
ABI-compatible with libotr 4.0, let's prevent this runtime check
from breaking packages that were built against 4.0 (Closes: #767230).
* Add symbols file: now that we have removed upstream's version check
at runtime, let's use the symbols mechanism to detect (most) ABI changes
automatically, and let reverse-dependencies pick up the version
of libotr they should depend on (Closes: #767652).
* debian/README.source: document how to detect and handle ABI changes.
