lacme (0.8.0) upstream;

 * Breaking change: 'challenge-directory' now needs to be set to an
   *existing* directory (writable by the lacme client user).  Since
   lacme(8) spawns a builtin webserver by default the change doesn't
   affect default configurations.
   Thanks to Benjamin Tietz for the idea and initial patch.
 * Breaking change: the 'iptables' option is now ignored unless the
   builtin webserver is used.
 * Unprivileged user/group for the internal client resp. webserver are
   now configurable at install time.
 * lacme: new flag `--force`, which aliases to `--min-days=-1`, i.e.,
   forces renewal regardless of the expiration date of existing
   certificates.
 * Remove decomissioned intermediate CAs Authority X3 and X4 from the
   bundle.
 * Remove cross-signed intermediate CAs from the bundle and add the
   (self-signed) ISRG Root X1 and X2 instead.  This allows us to fully
   validate provided X.509 chains using that self-contained bundle,
   regardless of which CAs is marqued as trusted under /etc/ssl/certs.
   This change bumps the minimum OpenSSL version to 1.1.0.
 * Breaking change: lacme(8) and lacme-accountd(1) respectively load
   their configuration file from /etc/lacme/lacme.conf resp.
   /etc/lacme/lacme-accountd.conf when running as root, and
   $XDG_CONFIG_HOME/lacme/lacme.conf resp.
   $XDG_CONFIG_HOME/lacme/lacme-accountd.conf when running as a normal
   user.  There is no fallback to /etc anymore, and the lookup in the
   current directory as prefered choice is removed too.  However
   lacme-accountd(1) can be used without configuration file under
   ~/.config/lacme as it treats a non-existent default location as an
   empty file.
 * The client, webserver, and accountd commands are now split on
   whitespace.  This doesn't change the default behavior but allows
   using `ssh -T lacme@account.example.net lacme-accountd` to spawn a
   remote lacme-accountd server for instance.
 * Add test suite against Let's Encrypt's staging environment
   https://letsencrypt.org/docs/staging-environment/ .
 * lacme(8)'s 'config' option in the [accountd] section no longer have a
   default value.  The previous default /etc/lacme/lacme-accountd.conf
   is still honored when root privileges are preserved (the default).
 * Deprecate setting 'privkey' in [accountd] section of the lacme(8)
   configuration file.  One need to use the lacme-accountd(1)
   configuration file for that instead.
 * lacme(8): add %-specifiers support for --config=, --socket=,
   --config-certs= (and 'socket'/'config-certs'/'challenge-directory'
   configuration options *before* privilege drop; and for the [accountd]
   section 'command'/'config' configuration options *after* privilege
   drop).
 * lacme-accountd(1): add %-specifiers support for --config=, --socket=
   and --privkey= (and 'socket'/'privkey' configuration options).
 * lacme-accountd(1): base64url-decode incoming signature requests shown
   in messages to the standard error.
 * lacme-accountd(1): new setting 'logfile' to log (decoded) incoming
   signature requests to a file.
 * lacme-accountd(1): new setting 'keyid' to easily revoke all account
   management access from the client.
 + Improve nginx/apache2 snippets for direct serving of challenge files
   (with the new 'challenge-directory' logic symlinks can be disabled).
 + Split Nginx and Apapche2 static configuration snippets into seperate
   files.  That way users prefering that over reverse-proxying can just
   source/enable the relevant files without having to uncomment
   anything.
 + Add support for TLS Feature extension from RFC 7633; this is mostly
   useful for OCSP Must-Staple.
 + client: use "lacme-client/$VERSION" as User-Agent header.
 + Consolidate error messages for consistency.
 + Sanitize environment when spawning the lacme client, webserver and
   accountd.
 + accountd: replace internal option --conn-fd=FD with flag --stdio.
   Using stdin/stdout makes it possible to tunnel the accountd
   connection through ssh.  The new flag is documented to allow safe
   usage is authorized_keys(5) restrictions.
 + Remove dependency on List::Util (core module).
 + accountd: Pass JWA and JWK thumbprint via extended greeting data.
   This gives better forward flexibility.
 - lacme: delay webserver socket shutdown to after the process has
   terminated.
 - documentation: suggest to generate private key material with
   genpkey(1ssl); also suggest a command to generate an ECDSA key not
   just RSA; hint at which key algorithms are supported.
 - documentation: clarify that "file:/path/to/account.key" can point to
   a symmetrically-encrypted private key.
 - documentation: emphasize default values in the config file, and move
   the most common options ('hash', 'keyUsage', 'CAfile', 'min-days') to
   the default section.
 - Raise client timeout from 10 to 30s.
 - Remove dependency on Types::Serialiser.
 - client: fail immediately when the accountd is unreachable.
 - Makefile: set executable bit for $(bindir)/lacme-accountd and
   $(sbindir)/lacme.
 - client: avoid "Use of uninitialized value in pattern match (m//)"
   perl warnings when the accountd socket can't be reached.
 - webserver: reopen stdin from /dev/null.
 - Use 'acme-challenge.XXXXXXXXXX' as template for the temporary ACME
   challenge directory.
 - Set the DEBUG environment variable to 0/1 instead of ""/1.
 - Use File::Basename::dirname() to correctly extract the parent
   directory of the socket path.
 - client: Print Terms of Service URL for 'account' command.

lacme (0.7) upstream;

 * Breaking change: the certificate indicated by 'CAfile' is no longer
   used as is in 'certificate-chain' (along with the leaf cert).  The
   chain returned by the ACME v2 endpoint is used instead.  This allows
   for more flexibility with respect to key/CA rotation, cf.
   https://letsencrypt.org/2020/11/06/own-two-feet.html and
   https://community.letsencrypt.org/t/beginning-issuance-from-r3/139018
 + 'CAfile' now defaults to @@datadir@@/lacme/ca-certificates.crt which
   is a concatenation of all known active CA certificates (which
   includes the previous default).

lacme (0.6.1) upstream;

 + Adapt Apache2 snippet to Apache2 2.4.
 + Ignore [accountd] section from lacme.conf when the --socket option is
   defined.  This allows remotely-controlled lacme processes being
   controlled without modifying an config files.
 * Makefile: major refactoring, add install and uninstall targets, honor
   BUILD_DOCDIR and DESTDIR variables.
 * Install lacme manual to section 8.
 * Change default libexec dir from /usr/lib/lacme to /usr/libexec/lacme.
 * Makefile: Use variables for target directories etc.

lacme (0.6) upstream;

 + client: poll order URL instead of each authz URL successively.
 + lacme: new option 'account --deactivate' for client-initiated account
   deactivation, see RFC 8555 sec. 7.3.6.
 - lacme, client: new dependency Date::Parse, don't parse RFC 3339
   datetime strings from X.509 certs manually.
 - lacme: assume that the iptables(8) binaries are under /usr/sbin not
   /sbin.  As of Buster this is the case, and the maintainer plans to
   drop compatibility symlinks once Bullseye is released.
 - Link to RFC 8555 <https://tools.ietf.org/html/rfc8555> instead of the
   ACME I-D URL.
 - Issue GET and POST-as-GET requests (RFC 8555 sec. 6.3) for the
   authorizations, order and certificate URLs.

lacme (0.5) upstream;

  + Use ACME v2 endpoints (update protocol to the last draft of the spec
    https://tools.ietf.org/html/draft-ietf-acme-acme-12 ).  Remove the
	'reg=' command, and rename the 'new-reg', 'new-cert' and
	'revoke-cert' commands to 'account', 'newOrder', and 'revokeCert'
	respectively, to match the the URI resource names.  For backward
	compatibility 'new-cert' and 'revoke-cert' remain supported.
  - Fix manpage generation with pandoc >=2.1

lacme (0.4) upstream;

  * Fix generation of manpages with pandoc >=1.18
  * Copy snippets/*.conf to /etc/lacme

lacme (0.3) upstream;

  + When parsing config-cert files and directories (default "lacme-certs.conf
    lacme-certs.conf.d"), import the default section of files read earlier.
  + new-cert: create certificate files atomically.
  + webserver: allow listening to multiple addresses (useful when
    dual IPv4/IPv6 stack is not supported).  Listen to a UNIX-domain
    socket by default </var/run/lacme-www.socket>.
  + webserver: don't install temporary iptables by default.  Hosts
    without a public HTTP daemon listening on port 80 need to set the
    'listen' option to [::] and/or 0.0.0.0, and possibly set the
    'iptables' option to Yes.
  + Change 'min-days' default from 10 to 21, to avoid expiration notices
    from Let's Encrypt when auto-renewal is done by a cronjob.
  + Provide nginx and apache2 configuration snippets.
  - Ensure lacme's config file descriptor is not passed to the accountd
    or webserver components.
  - new-cert: sort section names if not passed explicitely.
  - new-cert: new CLI option "min-days" overriding the value found in
    the configuration file.
  - new-cert: mark the basicConstraints (CA:FALSE) and keyUsage x509v3
    extensions as critical in the CSR, following upstream fix of
    Boulder's issue #565.
  - webserver: refuse to follow symlink when serving ACME challenge
    responses.  When dropping privileges to a dedicated UID
    (recommended) only the ACME client could write to its current
    directory anyway, so following symlinks was not a serious
    vulnerability.
  - lacme(1), lacme-accountd(1): fix version number shown with
    --version.
  - client: remove potential race when creating ACME challenge response
    files.
  - When using open with mode "<&=" or ">&=", ensure the expression
    (fileno) is interpreted as an integer.  (This failed in Perl v5.14.2
    from Debian Jessie.)
  - Specify minimum required Perl version (v5.14.2).  Moreover lacme(1)
    requires Socket 1.95 or later (for instance for IPPROTO_IPV6).

lacme (0.2) upstream;

  + Honor Retry-After headers for certificate issuance and challenge
    responses.
  + Update example of Subscriber Agreement URL to v1.1.1.
  + lacme: automaticall spawn lacme-acountd when a "[accountd]" section
    is present in the configuration file.  The "socket" option is then
    ignored, and the two processes communicate through a socket pair.
  + lacme: add an option --quiet to avoid mentioning valid certs (useful
    in cronjobs)
  + "config-certs" now points to a space separated list of files or
    directories.  New default "lacme-certs.conf lacme-certs.conf.d/".
  - Minor manpage fixes
  - More useful message upon Validation Challenge failure.
