# Release 20.09 {#sec-release-20.09}
The 20.09 release branch became the stable branch in late September,
2020.
## Highlights {#sec-release-20.09-highlights}
This release has the following notable changes:
- Nothing has happened.
## State Version Changes {#sec-release-20.09-state-version-changes}
The state version in this release includes the changes below. These
changes are only active if the `home.stateVersion` option is set to
\"20.09\" or later.
- The options [home.homeDirectory](#opt-home.homeDirectory) and
[home.username](#opt-home.username) no longer have default values and must
therefore be provided in your configuration. Previously their values
would default to the content of the environment variables `HOME` and
`USER`, respectively.
Further, the options [xdg.cacheHome](#opt-xdg.cacheHome),
[xdg.dataHome](#opt-xdg.dataHome) will no
longer be affected by the `XDG_CACHE_HOME`, `XDG_CONFIG_HOME`, and
`XDG_DATA_HOME` environment variables. They now unconditionally
default to
- `"${config.home.homeDirectory}/.cache"`,
- `"${config.home.homeDirectory}/.config"`, and
- `"${config.home.homeDirectory}/.local/share"`.
If you choose to switch to state version 20.09 then you must set
these options if you use non-default XDG base directory paths.
The initial configuration generated by
``` console
$ nix-shell '<home-manager>' -A install
```
will automatically include these options, when necessary.
- Git's `smtpEncryption` option is now set to `tls` only if both
[accounts.email.accounts._name_.smtp.tls.enable](#opt-accounts.email.accounts._name_.smtp.tls.enable) and
[accounts.email.accounts._name_.smtp.tls.useStartTls](#opt-accounts.email.accounts._name_.smtp.tls.useStartTls) are
`true`. If only
[accounts.email.accounts._name_.smtp.tls.enable](#opt-accounts.email.accounts._name_.smtp.tls.enable) is
`true`, `ssl` is used instead.
- The `nixpkgs` module no longer references `<nixpkgs>`. Before it
would do so when building the `pkgs` module argument. Starting with
state version 20.09, the `pkgs` argument is instead built from the
same Nixpkgs that was used to initialize the Home Manager modules.
This is useful, for example, when using Home Manager within a Nix
Flake. If you want to keep using `<nixpkgs>` with state version ≥
20.09 then add
``` nix
_module.args.pkgsPath = <nixpkgs>;
```
to your Home Manager configuration.
- The options `wayland.windowManager.sway.config.bars` and
`opt-xsession.windowManager.i3.config.bars` have been changed so
that most of the suboptions are now nullable and default to `null`.
The default for these two options has been changed to manually set
the old defaults for each suboption. The overall effect is that if
the `bars` options is not set, then the default remains the same. On
the other hand, something like:
``` nix
bars = [ {
command = "waybar";
} ];
```
will now create the config:
bar {
swaybar_command waybar
}
instead of
bar {
