* Removed built-in multi-user [[Authentication]], `SB_AUTH` is no longer supported, use `--user` or `SB_USER` instead, or an authentication layer such as [[Authelia]].
* Work on supporting multiple database as well as storage back-ends, reviving [[Install/Deno Deploy]] support.
* This is now documented on the brand new [[Install/Configuration]] page.
* A new `silverbullet sync` command to [[Sync]] spaces.
* Technical refactoring in preparation of multi-tenant deployment support (allowing you to run a single SB instance and serve multiple spaces and users at the same time)
* Lazy everything: plugs are now lazily loaded (after a first load, manifests are cached). On the server side, a whole lot of infrastructure is now only booted once the first HTTP request comes in
* Various bugfixes, primarily related to the new way of running docker containers, which broke things for some people. Be sure to have a look at the new [[Install/Configuration]] configuration options
* New {[Upload: File]} command to upload files and pictures (particularly valuable for mobile use cases). Implemented by [prcrst](https://github.com/silverbulletmd/silverbullet/pull/571).
* Basic [[Table of Contents]] support: any page _with 3 headers or more_, now has a “Table of Contents” widget appear (see this very page). You can toggle this feature using the {[Table of Contents: Toggle]} command.
* Tapping/clicking the top bar (outside of the page name and action buttons) now scrolls your page to the very top.
* The `Alt-q` command is now bound to the new {[Live Queries and Templates: Refresh All]} command refreshing all [[Live Queries]] and [[Live Templates]] on the page. This is to get y’all prepared to move away from directives.
* It’s likely that version 0.6.0 **will remove directives**, so please switch over to live queries and templates, e.g. using...
* The new {[Directive: Convert Entire Space to Live/Templates]} command, which will (attempt) to convert all uses of directives in your space automatically (backup your space before, though, just in case)
* It is now _recommended_ you tag all your templates with a `#template` tag, this will exclude them from [[Objects]] indexing and may in the future be used to do better template name completion (but not yet).
* New feature: Introducing [[Slash Templates]], allowing you to create custom [[Slash Commands]]. This deprecates snippets and page templates, because [[Slash Templates]] are awesomer.
* Many styling fixes and improvements to [[Live Queries]] and [[Live Templates]]
* Added a “source” button to [[Live Queries]] and [[Live Templates]] for better debugging (showing you the markdown code rendered by the template so you can more easily detect issues)
* Support for `render all` where the entire result set is passed to a single template allowing you to e.g. dynamically build up tables, see [[Live Queries$render]] for an example.
* The syntax to reference [[Anchors]] has now changed to use `$`, instead of `@` (e.g. [[Live Queries$render]]), the old syntax still works but is deprecated. The reason for this change is consistency: you define an anchor using the `$myanchor` syntax, referencing it the same way makes more sense.
Oh boy, this is a big one. This release brings you the following:
* [[Objects]]: a more generic system to indexing and querying content in your space, including the ability to define your own custom object “types” (dubbed [[Tags]]). See the referenced pages for examples.
* [[Live Queries]] and [[Live Templates]]: ultimately will replace [[🔌 Directive]] in future versions and **[[🔌 Directive]] is now deprecated.** They differ from directives in that they don’t materialize their output into the page itself, but rather render them on the fly so only the query/template instantiation is kept on disk. All previous directive examples on this website how now been replaced with [[Live Templates]] and [[Live Queries]]. To ease the conversion there is {[Directive: Convert Query to Live Query]} command: just put your cursor inside of an existing (query) directive and run it to auto-convert.
* The query syntax used in [[Live Queries]] (but also used in [[🔌 Directive]]) has been significantly expanded, although there may still be bugs. There’s still more value to be unlocked here in future releases.
* The previous “backlinks” plug is now built into SilverBullet as [[Linked Mentions]] and appears at the bottom of every page (if there are incoming links). You can toggle linked mentions via {[Mentions: Toggle]}.
* A whole bunch of [[PlugOS]] syscalls have been updated, I’ll do my best update known existing plugs, but if you built existing ones some things may have broken. Please report anything broken in [Github issues](https://github.com/silverbulletmd/silverbullet/issues).
* This release effectively already removes the `#eval` [[🔌 Directive]] (it’s still there, but likely not working), this directive needs some rethinking. Join us on [Discord](https://discord.gg/EvXbFucTxn) if you have a use case for it and how you use/want to use it.
* If you have plugs such as “backlinks” or “graphview” installed, please remove them (or to be safe: all plugs) from the `_plug` folder in your space after the upgrade. Then, also remove them from your [[PLUGS]] page. The backlinks plug is now included by default (named [[Linked Mentions]]), and GraphView still needs to be updated (although it’s been kind of abandoned by the author).
Due to significant changes in how data is stored, likely your space will be resynced to all your clients once you upgrade. Just in case you may also want to {[Space: Reindex]} your space. If things are really broken, try the {[Debug: Reset Client]} command.
The big change in this release is that SilverBullet now supports two [[Client Modes|client modes]]: _online_ mode and _sync_ mode. Read more about them here: [[Client Modes]].
* Removed [[Cloud Links]] support in favor of [[Federation]]. If you still have legacy cloud links, simply replace the 🌩️ with a `!` and things should work as before.
