+- [#1252](https://github.com/org-roam/org-roam/issues/1252) respect original link type during automatic replacement
+
+## 1.2.2 (06-10-2020)
+
+In this release we support fuzzy links of the form `[[roam:Title]]`, `[[roam:*Headline]]` and `[[roam:Title*Headline]]`. Completion for these fuzzy links is supported via `completion-at-point`.
+
+Org-roam now does not resolve symlinks. This significantly speeds up cache builds, but may result in some workflows breaking. In particular, Org-roam now cannot figure out if two distinct file paths in the Org-roam directory are the same file, and both files will be processed as if they were different files. This error seems to be unavoidable now that symlinks are not resolved, but this workflow is rare and should not affect most users.
+
+This change requires you to set `org-roam-directory` to the resolved path of a folder. That is:
+
+```elisp
+(setq org-roam-directory (file-truename "/path/to/directory/"))
+```
+
+### Breaking Changes
+
+- [#1164](https://github.com/org-roam/org-roam/pull/1164) Org-roam now stores the database in the user's Emacs directory by default
+- [#910](https://github.com/org-roam/org-roam/pull/910) Deprecate `company-org-roam`, using `completion-at-point` instead. To use this with company, add the `company-capf` backend instead.
+- [#1109](https://github.com/org-roam/org-roam/pull/1109) Org-roam now does not resolve symlinks.

+- [#994](https://github.com/org-roam/org-roam/pull/994) Simplify org-roam-store-link

+<img src="https://www.orgroam.com/img/logo.svg" align="right" alt="Org-roam Logo" width="240">
 
-Org-roam is a [Roam][roamresearch] replica built on top of the
-all-powerful [Org-mode][org].
+Org-roam is a plain-text knowledge management system. It brings some of
+[Roam's][roamresearch] more powerful features into the [Org-mode][org]
+ecosystem.
 
-Org-roam is a solution for effortless non-hierarchical note-taking
-with Org-mode. With Org-roam, notes flow naturally, making note-taking
-fun and easy. Org-roam should also work as a plug-and-play solution
-for anyone already using Org-mode for their personal wiki.
+Org-roam borrows principles from the Zettelkasten method, providing a solution
+for non-hierarchical note-taking. It should also work as a plug-and-play
+solution for anyone already using Org-mode for their personal wiki.
 
-Org-roam aims to implement the core features of Roam, leveraging the
-mature ecosystem around Org-mode where possible. Eventually, we hope
-to further introduce features enabled by the Emacs ecosystem.
+- **Private and Secure**: Edit your personal wiki completely offline, entirely
+  in your control. Encrypt your notes with GPG. Take lasting notes in
+  plain-text.
+- **Networked Thought**: Connect notes and thoughts together with ease using
+  backlinks. Discover surprising and previously unseen connections in your notes
+  with the built-in graph visualization.
+- **Extensible and Powerful**: Leverage Emacs' fantastic text-editing interface,
+  and the mature Emacs and Org-mode ecosystem of packages.
+- **Free and Open Source**: Org-roam is licensed under the GNU General Public
+  License version 3 or later.

-
-Here's a screencast of Org-roam. The `org-roam-buffer` (window on the
-right) shows backlinks for the active Org-roam buffer (window on the
-left), as well as the surrounding content in the backlink file. The
-database is built once, and updated incrementally. The graph is
-generated from the link structure, and can be used to navigate to the
-respective files.
