+v3.2.0
+======
+
+Release Summary
+---------------
+
+Bugfix and feature release.
+
+This release is dedicated to the memory of `Michael O. Rabin <https://en.wikipedia.org/wiki/Michael_O._Rabin>`__, who passed away a few days before this release.
+
+Minor Changes
+-------------
+
+- acme_* modules - experimentally support ``dns-account-01`` challenge type according to `acme-dns-account-label draft 02 <https://datatracker.ietf.org/doc/html/draft-ietf-acme-dns-account-label-02>`__. Note that breaking changes to this challenge type can also happen in minor releases until the acme-dns-account-label draft has been finalized as an RFC (https://github.com/ansible-collections/community.crypto/pull/996).
+- acme_* modules - experimentally support ``dns-persist-01`` challenge type according to `acme-dns-persist draft 01 <https://www.ietf.org/archive/id/draft-ietf-acme-dns-persist-01.html>`__. Note that breaking changes to this challenge type can also happen in minor releases until the acme-dns-persist draft has been finalized as an RFC (https://github.com/ansible-collections/community.crypto/pull/997).
+
+Bugfixes
+--------
+
+- acme_* modules - improve handling of authz deactivation, and improve error message in case of bad authz states (https://github.com/ansible-collections/community.crypto/pull/998).
+
+New Plugins

+
+v3.0.0
+======
+
+Release Summary
+---------------
+
+New major release of community.crypto with a lot of code modernization.
+This release drops compatibility for ansible-core before 2.17, for Python
+before 3.7, and for cryptography before 3.3.
+It also removes all Entrust modules, and the Entrust provider for the
+``community.crypto.x509_certificate*`` modules.
+
+See below for a more detailled list of changes.
+
+Minor Changes
+-------------
+
+- No longer provide cryptography's ``backend`` parameter. This will break with cryptography < 3.1 (https://github.com/ansible-collections/community.crypto/pull/878).
+- On cryptography 36.0.0+, always use ``public_bytes()`` for X.509 extension objects instead of using cryptography internals to obtain DER value of extension (https://github.com/ansible-collections/community.crypto/pull/878).
+- Python code modernization: add type hints and type checking (https://github.com/ansible-collections/community.crypto/pull/885).
+- Python code modernization: avoid unnecessary string conversion (https://github.com/ansible-collections/community.crypto/pull/880).
+- Python code modernization: avoid using ``six`` (https://github.com/ansible-collections/community.crypto/pull/884).
+- Python code modernization: remove Python 3 specific code (https://github.com/ansible-collections/community.crypto/pull/877).
+- Python code modernization: update ``__future__`` imports, remove Python 2 specific boilerplates (https://github.com/ansible-collections/community.crypto/pull/876).
+- Python code modernization: use ``unittest.mock`` instead of ``ansible_collections.community.internal_test_tools.tests.unit.compat.mock`` (https://github.com/ansible-collections/community.crypto/pull/881).
+- Python code modernization: use f-strings instead of ``%`` and ``str.format()`` (https://github.com/ansible-collections/community.crypto/pull/875).
+- Remove ``backend`` parameter from internal code whenever possible (https://github.com/ansible-collections/community.crypto/pull/883).
+- Remove various compatibility code for cryptography < 3.3 (https://github.com/ansible-collections/community.crypto/pull/878).
+- Remove various no longer needed abstraction layers for multiple backends (https://github.com/ansible-collections/community.crypto/pull/912).
+- Remove vendored copy of ``distutils.version`` in favor of vendored copy included with ansible-core 2.12+ (https://github.com/ansible-collections/community.crypto/pull/371).
+- Various code refactorings (https://github.com/ansible-collections/community.crypto/pull/905, https://github.com/ansible-collections/community.crypto/pull/909, https://github.com/ansible-collections/community.crypto/pull/911, https://github.com/ansible-collections/community.crypto/pull/913, https://github.com/ansible-collections/community.crypto/pull/914, https://github.com/ansible-collections/community.crypto/pull/917).
+- acme_* modules - improve parsing of ``Retry-After`` reply headers in regular ACME requests (https://github.com/ansible-collections/community.crypto/pull/890).
+- action_module plugin utils - remove compatibility with older ansible-core/ansible-base/Ansible versions (https://github.com/ansible-collections/community.crypto/pull/872).
+- x509_certificate, x509_certificate_pipe - the ``ownca_version`` and ``selfsigned_version`` parameters explicitly only allow the value ``3``. The module already failed for other values in the past, now this is validated as part of the module argument spec (https://github.com/ansible-collections/community.crypto/pull/890).
+
+Breaking Changes / Porting Guide
+--------------------------------
+
+- All doc_fragments are now private to the collection and must not be used from other collections or unrelated plugins/modules. Breaking changes in these can happen at any time, even in bugfix releases (https://github.com/ansible-collections/community.crypto/pull/898).
+- All module_utils and plugin_utils are now private to the collection and must not be used from other collections or unrelated plugins/modules. Breaking changes in these can happen at any time, even in bugfix releases (https://github.com/ansible-collections/community.crypto/pull/887).
+- Ignore value of ``select_crypto_backend`` for all modules except acme_* and ..., and always assume the value ``auto``. This ensures that the ``cryptography`` version is always checked (https://github.com/ansible-collections/community.crypto/pull/883).
+- The validation for relative timestamps is now more strict. A string starting with ``+`` or ``-`` must be valid, otherwise validation will fail. In the past such strings were often silently ignored, and in many cases the code which triggered the validation was not able to handle no result (https://github.com/ansible-collections/community.crypto/pull/885).
+- acme.certificates module utils - the ``retrieve_acme_v1_certificate()`` helper function has been removed (https://github.com/ansible-collections/community.crypto/pull/873).
+- get_certificate - the default for ``asn1_base64`` changed from ``false`` to ``true`` (https://github.com/ansible-collections/community.crypto/pull/873).
+- x509_crl - the ``mode`` parameter no longer denotes the update mode, but the CRL file mode. Use ``crl_mode`` instead for the update mode (https://github.com/ansible-collections/community.crypto/pull/873).
+
+Deprecated Features
+-------------------
+
+- acme_certificate - deprecate the ``agreement`` option which has no more effect. It will be removed from community.crypto 4.0.0 (https://github.com/ansible-collections/community.crypto/pull/891).
+- acme_certificate - the option ``modify_account``'s default value ``true`` has been deprecated. It will change to ``false`` in community.crypto 4.0.0. We recommend to set the option to an explicit value to avoid deprecation warnings, and to prefer setting it to ``false`` already now. Better use the ``community.crypto.acme_account`` module instead (https://github.com/ansible-collections/community.crypto/issues/924).
+- openssl_pkcs12 - deprecate the ``maciter_size`` option which has no more effect. It will be removed from community.crypto 4.0.0 (https://github.com/ansible-collections/community.crypto/pull/891).
+
+Removed Features (previously deprecated)
+----------------------------------------
+
+- All Entrust content is being removed since the Entrust service in currently being sunsetted after the sale of Entrust's Public Certificates Business to Sectigo; see `the announcement with key dates <https://www.entrust.com/tls-certificate-information-center>`__ and `the migration brief for customers <https://www.sectigo.com/uploads/resources/EOL_Migration-Brief-End-Customer.pdf>`__ for details. Since this process will be completed in 2025, we decided to remove all Entrust content from community.general 3.0.0 (https://github.com/ansible-collections/community.crypto/issues/895, https://github.com/ansible-collections/community.crypto/pull/901).
+- The collection no longer supports cryptography < 3.3 (https://github.com/ansible-collections/community.crypto/pull/878, https://github.com/ansible-collections/community.crypto/pull/882).
+- acme.acme module utils - the ``get_default_argspec()`` function has been removed. Use ``create_default_argspec()`` instead (https://github.com/ansible-collections/community.crypto/pull/873).
+- acme.backends module utils - the methods ``get_ordered_csr_identifiers()`` and ``get_cert_information()`` of ``CryptoBackend`` now must be implemented (https://github.com/ansible-collections/community.crypto/pull/873).
+- acme.documentation docs fragment - the ``documentation`` docs fragment has been removed. Use both the ``basic`` and ``account`` docs fragments in ``acme`` instead (https://github.com/ansible-collections/community.crypto/pull/873).
+- acme_* modules - support for ACME v1 has been removed (https://github.com/ansible-collections/community.crypto/pull/873).
+- community.crypto no longer supports Ansible 2.9, ansible-base 2.10, and ansible-core versions 2.11, 2.12, 2.13, 2.14, 2.15, and 2.16. While content from this collection might still work with some older versions of ansible-core, it will not work with any Python version before 3.7 (https://github.com/ansible-collections/community.crypto/pull/870).
+- crypto.basic module utils - remove ``CRYPTOGRAPHY_HAS_*`` flags. All tested features are supported since cryptography 3.0 (https://github.com/ansible-collections/community.crypto/pull/878).
+- crypto.cryptography_support module utils - remove ``cryptography_serial_number_of_cert()`` helper function (https://github.com/ansible-collections/community.crypto/pull/878).
+- crypto.module_backends.common module utils - this module utils has been removed. Use the ``argspec`` module utils instead (https://github.com/ansible-collections/community.crypto/pull/873).
+- crypto.support module utils - remove ``pyopenssl`` backend (https://github.com/ansible-collections/community.crypto/pull/874).
+- ecs_certificate - the module has been removed. Please use community.crypto 2.x.y if you need this module (https://github.com/ansible-collections/community.crypto/pull/900).
+- ecs_domain - the module has been removed. Please use community.crypto 2.x.y if you need this module (https://github.com/ansible-collections/community.crypto/pull/900).
+- execution environment dependencies - remove PyOpenSSL dependency (https://github.com/ansible-collections/community.crypto/pull/874).
+- openssl_csr_pipe - the module now ignores check mode and will always behave as if check mode is not active (https://github.com/ansible-collections/community.crypto/pull/873).
+- openssl_pkcs12 - support for the ``pyopenssl`` backend has been removed (https://github.com/ansible-collections/community.crypto/pull/873).
+- openssl_privatekey_pipe - the module now ignores check mode and will always behave as if check mode is not active (https://github.com/ansible-collections/community.crypto/pull/873).
+- time module utils - remove ``pyopenssl`` backend (https://github.com/ansible-collections/community.crypto/pull/874).
+- x509_certificate - the ``entrust`` provider has been removed. Please use community.crypto 2.x.y if you need this provider (https://github.com/ansible-collections/community.crypto/pull/900).
+- x509_certificate_pipe - the ``entrust`` provider has been removed. Please use community.crypto 2.x.y if you need this provider (https://github.com/ansible-collections/community.crypto/pull/900).
+- x509_certificate_pipe - the module now ignores check mode and will always behave as if check mode is not active (https://github.com/ansible-collections/community.crypto/pull/873).
+
+Bugfixes
+--------
+
+- acme_account - make work with CAs that do not accept any account request without External Account Binding data (https://github.com/ansible-collections/community.crypto/issues/918, https://github.com/ansible-collections/community.crypto/pull/919).
+- openssl_csr, openssl_csr_pipe - avoid accessing internal members of cryptography's ``KeyUsage`` extension object (https://github.com/ansible-collections/community.crypto/pull/910).
+

 We plan to regularly release minor and patch versions, whenever new features are added or bugs fixed. Our collection follows [semantic versioning](https://semver.org/), so breaking changes will only happen in major releases.
 
-Most modules will drop PyOpenSSL support in version 2.0.0 of the collection, i.e. in the next major version. We currently plan to release 2.0.0 somewhen during 2021. Around then, the supported versions of the most common distributions will contain a new enough version of ``cryptography``.
-
-Once 2.0.0 has been released, bugfixes will still be backported to 1.0.0 for some time, and some features might also be backported. If we do not want to backport something ourselves because we think it is not worth the effort, backport PRs by non-maintainers are usually accepted.
-
-In 2.0.0, the following notable features will be removed:
-* PyOpenSSL backends of all modules, except ``openssl_pkcs12`` which does not have a ``cryptography`` backend due to lack of support of PKCS#12 functionality in ``cryptography``.
-* The ``assertonly`` provider of ``x509_certificate`` will be removed.

+          these can happen at any time, even in bugfix releases (https://github.com/ansible-collections/community.crypto/pull/898).

+          must not be used from other collections or unrelated plugins/modules. Breaking
+          changes in these can happen at any time, even in bugfix releases (https://github.com/ansible-collections/community.crypto/pull/887).
+        - Ignore value of ``select_crypto_backend`` for all modules except acme_*
+          and ..., and always assume the value ``auto``. This ensures that the ``cryptography``
+          version is always checked (https://github.com/ansible-collections/community.crypto/pull/883).
+        - The validation for relative timestamps is now more strict. A string starting
+          with ``+`` or ``-`` must be valid, otherwise validation will fail. In the
+          past such strings were often silently ignored, and in many cases the code
+          which triggered the validation was not able to handle no result (https://github.com/ansible-collections/community.crypto/pull/885).
+        - acme.certificates module utils - the ``retrieve_acme_v1_certificate()``
+          helper function has been removed (https://github.com/ansible-collections/community.crypto/pull/873).
+        - get_certificate - the default for ``asn1_base64`` changed from ``false``
+          to ``true`` (https://github.com/ansible-collections/community.crypto/pull/873).
+        - x509_crl - the ``mode`` parameter no longer denotes the update mode, but
+          the CRL file mode. Use ``crl_mode`` instead for the update mode (https://github.com/ansible-collections/community.crypto/pull/873).
+      deprecated_features:
+        - acme_certificate - deprecate the ``agreement`` option which has no more
+          effect. It will be removed from community.crypto 4.0.0 (https://github.com/ansible-collections/community.crypto/pull/891).
+        - openssl_pkcs12 - deprecate the ``maciter_size`` option which has no more
+          effect. It will be removed from community.crypto 4.0.0 (https://github.com/ansible-collections/community.crypto/pull/891).
+      minor_changes:
+        - No longer provide cryptography's ``backend`` parameter. This will break
+          with cryptography < 3.1 (https://github.com/ansible-collections/community.crypto/pull/878).
+        - On cryptography 36.0.0+, always use ``public_bytes()`` for X.509 extension
+          objects instead of using cryptography internals to obtain DER value of extension
+          (https://github.com/ansible-collections/community.crypto/pull/878).

+        - Remove various compatibility code for cryptography < 3.3 (https://github.com/ansible-collections/community.crypto/pull/878).

+          included with ansible-core 2.12+ (https://github.com/ansible-collections/community.crypto/pull/371).
+        - acme_* modules - improve parsing of ``Retry-After`` reply headers in regular
+          ACME requests (https://github.com/ansible-collections/community.crypto/pull/890).
+        - action_module plugin utils - remove compatibility with older ansible-core/ansible-base/Ansible

-# end class StrictVersion
-
-# The rules according to Greg Stein:
-# 1) a version number has 1 or more numbers separated by a period or by
-#    sequences of letters. If only periods, then these are compared
-#    left-to-right to determine an ordering.
-# 2) sequences of letters are part of the tuple for comparison and are
-#    compared lexicographically
-# 3) recognize the numeric components may have leading zeroes
-#
-# The LooseVersion class below implements these rules: a version number
-# string is split up into a tuple of integer and string components, and
-# comparison is a simple tuple comparison.  This means that version
-# numbers behave in a predictable and obvious way, but a way that might
-# not necessarily be how people *want* version numbers to behave.  There
-# wouldn't be a problem if people could stick to purely numeric version
-# numbers: just split on period and compare the numbers as tuples.
-# However, people insist on putting letters into their version numbers;
-# the most common purpose seems to be:
-#   - indicating a "pre-release" version
-#     ('alpha', 'beta', 'a', 'b', 'pre', 'p')
-#   - indicating a post-release patch ('p', 'pl', 'patch')
-# but of course this can't cover all version number schemes, and there's
-# no way to know what a programmer means without asking him.
-#
-# The problem is what to do with letters (and other non-numeric
-# characters) in a version number.  The current implementation does the
-# obvious and predictable thing: keep them as strings and compare
-# lexically within a tuple comparison.  This has the desired effect if
-# an appended letter sequence implies something "post-release":
-# eg. "0.99" < "0.99pl14" < "1.0", and "5.001" < "5.001m" < "5.002".
-#
-# However, if letters in a version number imply a pre-release version,
-# the "obvious" thing isn't correct.  Eg. you would expect that
-# "1.5.1" < "1.5.2a2" < "1.5.2", but under the tuple/lexical comparison
-# implemented here, this just isn't so.
-#
-# Two possible solutions come to mind.  The first is to tie the
-# comparison algorithm to a particular set of semantic rules, as has
-# been done in the StrictVersion class above.  This works great as long
-# as everyone can go along with bondage and discipline.  Hopefully a
-# (large) subset of Python module programmers will agree that the
-# particular flavour of bondage and discipline provided by StrictVersion
-# provides enough benefit to be worth using, and will submit their
-# version numbering scheme to its domination.  The free-thinking
-# anarchists in the lot will never give in, though, and something needs
-# to be done to accommodate them.
-#
-# Perhaps a "moderately strict" version class could be implemented that
-# lets almost anything slide (syntactically), and makes some heuristic
-# assumptions about non-digits in version number strings.  This could
-# sink into special-case-hell, though; if I was as talented and
-# idiosyncratic as Larry Wall, I'd go ahead and implement a class that
-# somehow knows that "1.2.1" < "1.2.2a2" < "1.2.2" < "1.2.2pl3", and is
-# just as happy dealing with things like "2g6" and "1.13++".  I don't
-# think I'm smart enough to do it right though.
-#
-# In any case, I've coded the test suite for this module (see
-# ../test/test_version.py) specifically to fail on things like comparing
-# "1.2a2" and "1.2".  That's not because the *code* is doing anything
-# wrong, it's because the simple, obvious design doesn't match my
-# complicated, hairy expectations for real-world version numbers.  It
-# would be a snap to fix the test suite to say, "Yep, LooseVersion does
-# the Right Thing" (ie. the code matches the conception).  But I'd rather
-# have a conception that matches common notions about version numbers.
-

-class LooseVersion(Version):
-    """Version numbering for anarchists and software realists.
-    Implements the standard interface for version number classes as
-    described above.  A version number consists of a series of numbers,
-    separated by either periods or strings of letters.  When comparing
-    version numbers, the numeric components will be compared
-    numerically, and the alphabetic components lexically.  The following
-    are all valid version numbers, in no particular order:
-
-        1.5.1
-        1.5.2b2
-        161
-        3.10a
-        8.02
-        3.4j
-        1996.07.12
-        3.2.pl0
-        3.1.1.6
-        2g6
-        11g
-        0.960923
-        2.2beta29
-        1.13++
-        5.5.kw
-        2.0b1pl0
-
-    In fact, there is no such thing as an invalid version number under
-    this scheme; the rules for comparison are simple and predictable,
-    but may not always give the results you want (for some definition
-    of "want").
