## [1.0.0] 2019-08-20

### Added

- New parameter `--max=X` is added for `autogen` (generate kernels
  base on `.out-of-tree.toml` definitions) and `pew` (automated
  runs) and allows to specify a maximum number of runs per each
  supported kernel in module/exploit definition.

- New command `genall` -- generate all kernels for specified
  distro/version.

- All logs stores in sqlite3 database. Implemented specific commands
  for making simple queries and export data to markdown and json.

- Implemented success rate calculation for previous runs.

- Save of build results supported by parameter `--dist` for `pew`.

- Support for generating kernels info from host system.

- Support for build on host.

- Support for custom kernels.

- Now debugging environment is automatically looking for debug
  kernel on the host system.

- Added ability to enable/disable kaslr/smep/smap/kpti for debugging
  by command line flags.

- New parameter `--threads=N` is added for `pew` and allows to
  specify maximum number of threads that will be used for parallel
  build/run/test.

- Tagging for runs. Tags write to log and can be used for
  statistics.

- Added non-regex way to set kernel version in .out-of-tree.toml (see
  examples).

- New command `pack` that perform tests in subdirectories.

- Added ability to disable kaslr/smep/smap/kpti for in artifact
  definition.

- Added ability to change amount of memory/CPUs and set qemu timeout
  in artifact definition (`.out-of-tree.toml`).

- Now images downloading while `kernel autogen`, bootstrap is not
  required anymore.

- Support CentOS kernels.

### Changed

- Now if there's no base image found — out-of-tree will try to use
  an image from closest previous version, e.g. image from Ubuntu
  18.04 for Ubuntu 18.10.

- Kernel modules tests will not be failed if there are no tests
  exists.

- Now *out-of-tree* will return negative error code if at least one
  of the stage was failed.

- Project is switch to use Go modules.

- Now test.sh is used by default if copying is not implemented in
  Makefile.

- dmesg is not cleaned before the start of module/exploit anymore.

- qemu/kvm will use all host cpu features.

### Removed

- *Kernel factory* is removed completely in favor of incremental
  Dockerfiles.

- `bootstrap` is not doing anything anymore. It'll be removed in next
  release.

### Fixed

- Command `timeout` is not required anymore.

- Errors is more meaningful.

- Temporary files is moved to `~/.out-of-tree/tmp/` to avoid docker
  mounting issues on some systems.

## [0.2.0] - 2019-12-01

The main purpose of the release is to simplify installation.

### Changes

- All configuration moved to `~/.out-of-tree`.

- Now prebuilt images can be downloaded with bootstrap.

- Ability to generate kernels specific to .out-of-tree.toml in
  current directory. So now there's no need to wait for several
  hours for start work on specific kernel with module/exploit.

- Now there's no need to keep source tree and _out-of-tree_ can be
  distributed in binary form.

- New command: **debug**. Creates interactive environment for kernel
  module/exploit development. Still work-in-progress.

- No warning anymore if test.sh is not exists.

## [0.1.0] - 2019-11-20
