It should also work on other BSD although it has not been tested. ## [0.9.0] - 2020-08-01 ### Added - System users and groups can now be specified by name in addition to uid/gid. ### Changed - The HTTP(S) part is now handled by `attohttpc` instead of `reqwest`. ### Fixed - In tacd, the `--acme-ext-file` parameter is now in conflict with `acme-ext` instead of itself. ## [0.8.0] - 2020-06-12 ### Changed - The HTTP(S) part is now handled by `reqwest` instead of `http_req`. ## Fixed - `make install` now work with the busybox toolchain. ## [0.7.0] - 2020-03-12 ### Added - Wildcard certificates are now supported.

The proof is a string representation of the acmeIdentifier extension. The self-signed certificate itself has to be built by a hook. ### Changed - In the configuration, the `email` certificate field has been replaced by the `account` field which matches an account object. - The format of the `domain` configuration variable has changed and now includes the challenge type. - The `token` challenge hook variable has been renamed `file_name`. - The `challenge_hooks`, `post_operation_hooks`, `file_pre_create_hooks`, `file_post_create_hooks`, `file_pre_edit_hooks` and `file_post_edit_hooks` certificate variables has been replaced by `hooks`. - The logs has been purged from many useless debug and trace entries. ### Removed - The DER storage format has been removed. - The `challenge` certificate variables has been removed. ## [0.2.1] - 2019-03-30 ### Changed - The bug that prevented from requesting more than two certificates has been fixed. ## [0.2.0] - 2019-03-27 ### Added - The `kp_reuse` flag allow to reuse a key pair instead of creating a new one at each renewal. - It is now possible to define hook groups that can reference either hooks or other hook groups. - Hooks can be defined when before and after a file is created or edited (`file_pre_create_hooks`, `file_post_create_hooks`, `file_pre_edit_hooks` and `file_post_edit_hooks`). - It is now possible to send logs either to syslog or stderr using the `--to-syslog` and `--to-stderr` arguments. ### Changed - `post_operation_hook` has been renamed `post_operation_hooks`. - By default, logs are now sent to syslog instead of stderr. - The process is now daemonized by default. It is possible to still run it in the foreground using the `--foregroung` flag.
