## 0.15.0 (2022-xx-xx)
**BREAKING**:
**Note:** Take a backup of your database before upgrading.
### BREAKING
- Boundaries between Namespaces has been removed and all nodes can communicate by default [#357](https://github.com/juanfont/headscale/pull/357)
- To limit access between nodes, use [ACLs](./docs/acls.md).
**Features**:
### Features
- Add support for writing ACL files with YAML [#359](https://github.com/juanfont/headscale/pull/359)
- Users can now use emails in ACL's groups [#372](https://github.com/juanfont/headscale/issues/372)
- Add shorthand aliases for commands and subcommands [#376](https://github.com/juanfont/headscale/pull/376)
**Changes**:
### Changes
- Fix a bug were the same IP could be assigned to multiple hosts if joined in quick succession [#346](https://github.com/juanfont/headscale/pull/346)
- Simplify the code behind registration of machines [#366](https://github.com/juanfont/headscale/pull/366)
- Nodes are now only written to database if they are registrated successfully
- Fix a limitation in the ACLs that prevented users to write rules with `*` as source [#374](https://github.com/juanfont/headscale/issues/374)
**0.14.0 (2022-02-24):**

From the **next\*\* version (`0.15.0`), all machines will be able to communicate regardless of
if they are in the same namespace. This means that the behaviour currently limited to ACLs
will become default. From version `0.15.0`, all limitation of communications must be done
with ACLs.
This is a part of aligning `headscale`'s behaviour with Tailscale's upstream behaviour.
**BREAKING**:
### BREAKING
- ACLs have been rewritten to align with the bevaviour Tailscale Control Panel provides. **NOTE:** This is only active if you use ACLs
- Namespaces are now treated as Users
