Version 0.9.1
-------------
_Unstable icy waters_
Released: 2020-11-30

* Bug fixes for integrated thunderbolt controllers:
  On Ice Lake, the Thunderbolt 3 i/o subsystem is fully integrated into the die.
  As a side effect it does not have a DROM, which means the host udev device
  does not have the device and vendor name and id attributes.
  Additionally the `unique_id` of said host controller changes with every boot,
  which breaks one of the fundamental assumptions in `boltd`. Therefore a number
  of bug fixes were necessary to properly support this new architecture:

  - Don't store domains where uuids change across reboots [!220]
  - Fixes for the journal and the domain's acl-log [!221]
  - Version the store and use that to clean up stale domains once [!226, !231]
  - Host identification for embedded thunderbolt controllers [!233]

* Various other small bug fixes and memory leak fixes.

Version 0.8
-----------
_I owe it to the MM U!_
Released: 2019-06-14

* New Features:
  - **IOMMU support**: adapt behavior iommu support is present and active [#128]

Version 0.6
-----------
_Make the firmware do it!_
Released: 2018-11-28

* New Features:
  - **pre-boot access control list, aka. `BootACL`** support [!119]
    - domains objects are now persistent
      - new `Uid` (dbus) / `uid` (object) property derived from the uuid of the device representing the root switch
      - `sysfs` and `id` attribute will be set/unset on connects and disconnects
      - domains are now stored in the boltd database
    - domains got the `BootACL` (dbus) / `bootacl` (object) property
      - uuids can be added, removed or set in batch
      - when domain is *online*: changes are written to the sysfs `boot_acl` attribute directly
      - when domain is *offline*: changes are written to a journal and then reapplied in order when the domain is connected
    - newly enrolled devices get added to all bootacls of all domains *if* the `policy` is `BOLT_POLICY_AUTO`
    - removed devices get deleted from all bootacls of all domains
    - `boltacl domain` command will show the bootacl slots and their content

  - `boltctl` gained the `-U, --uuid` option, to control how uuids are printed [!124]

* Improvements and fixes:
  - Testing [!127]
    - The test coverage increased to `84.80%` overall and to `90.0%` for the `boltd` source
    - Coverage is reported for merge requests via the fedora ci image [!126]
    - `boltctl` is now included in the tests [!132]
    - Fedora 29 is used for the fedora ci image

  - Bugs and robustness:
    - The device state is verified in `Device.Authorize` [!120]
    - Handle empty 'keys' sysfs device attribute [!129]
    - Properly adjust policies when enrolling already authorized devices [!136]
    - Fix potential crash when logging assertions `g_return_if_fail` [!121]

Version 0.3
-----------
_Capture The Flags_
Released: 2018-05-28

* Prepare for upcoming kernel changes:
  - Support for `usbonly` (SL4) security level (#75)
  - Support for `boot` sysfs device attribute (#76)

* DBus API changes:
  - `BoltStatus` was split (#81), so that:
      - `Device.Status` does not report `authorized-xxx` anymore
      - `Device.AuthFlags` added to indicate auth details, e.g. `secure`, `nopci`, `boot`, `nokey` (#76)
  - `BoltSecurity` and thus `Manager.SecurityLevel` can report `usbonly` (#75)

* client/boltctl:
  - async versions for many function calls
  - more efficient getters, resulting in reduced allocations
  - boltctl reports `Device.AuthFlags`
  - boltctl prints more and better version info via `boltctl monitor`

* Other bugfixes and improvements include:
  - more robust flags/enum conversion


Version 0.2
-----------
_I broke the Bus_
Released: 2018-03-06

Lots of changes, the most significant:

- database location moved (now in `/var/lib/boltd`)
  - **⚠** devices enrolled with bolt 0.1 need to be re-enrolled (or the database moved from the old location)

- DBus API changed (lots of strings)

- Enums are transmitted as strings
  - `Device.Security` property is gone; replaced by `authorized-dponly` status and `Manager.SecurityLevel` ( #37, #38, #62)
  - Various timestamps got added: `Device.ConnectTime`, `Device.StoreTime` and `Device.AuthorizeTime` (#46  #57)
  - `Device.Label` (readwrite) was added so devices can be given custom names (#46)
  - `Device.Type` added, to differentiate between host and peripherals
  - `Manager.AuthMode` (readwrite) was added to control (auto) authorization (#48)

Other bugfixes and improvements include:

- Ensure we get a `DeviceAdded` signal on startup (#58)
 - Support for legacy devices that have no key sysfs attribute (#67)
 - Use structured logging and avoid printing UUIDs in non-debug log code (#36 #60)
 - Other internal restructuring for cleaner code (#43)


Version 0.1
-----------
