+- [#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.
+
+### Features

+- [#1032](https://github.com/org-roam/org-roam/pull/1032) File changes are now propagated to the database on idle timer. This prevents large wait times during file saves.
+- [#974](https://github.com/org-roam/org-roam/pull/974) Protect region targeted by `org-roam-insert`
+- [#994](https://github.com/org-roam/org-roam/pull/994) Simplify org-roam-store-link

+
+### Bugfixes
+
+- [#1057](https://github.com/org-roam/org-roam/pull/1057) Improve performance of database builds by preventing generation of LaTeX and image previews.
+- [#1103](https://github.com/org-roam/org-roam/pull/1103) Fix long build-times for Windows on files with URL links
+
+## 1.2.1 (27-07-2020)
+
+This release consisted of a big deal of refactoring and bug fixes. Notably, we fixed several catastrophic failures on db builds with bad setups (#854), and modularized tag and title extractions.
+
+We also added some new features that had been a long time coming:
+
+1. We made the backlinks more outline-friendly by also showing the outline hierarchy for a backlink (#863)
+2. We now support nested captures, which is crucial for `org-roam-protocol` (#966)
+
+### Breaking Changes
+
+- [#908](https://github.com/org-roam/org-roam/pull/908) Normalized titles in database. May break external packages that rely on unnormalized titles.
+
+### Features

+- [#847](https://github.com/org-roam/org-roam/pull/847) Use sqlite3 transactions instead of storing the values to be inserted.
+- [#851](https://github.com/org-roam/org-roam/pull/851) Add `'first-directory'` option for `org-roam-tag-sources`
+- [#863](https://github.com/org-roam/org-roam/pull/863) Display outline hierarchy in backlinks buffer

+- [#966](https://github.com/org-roam/org-roam/pull/966) Enable nested captures
+
+### Bugfixes
+
+- [#854](https://github.com/org-roam/org-roam/pull/854) Warn instead of fail when duplicate refs and IDs exist.
+- [#857](https://github.com/org-roam/org-roam/pull/857) Fix tag extraction for symlinked directories.
+- [#894](https://github.com/org-roam/org-roam/pull/894) Perform link fixes on all Org-roam files
+- [#952](https://github.com/org-roam/org-roam/pull/952) Cache `${foo}` template variables so they do not need to be re-entered twice
+
 ## 1.2.0 (12-06-2020)
 
 In this release, we improved the linking process by achieving feature parity between links to files and links to headlines. Before, we used the `file:foo::*bar` format to link to the headline `bar` in file `foo`, but this was prone to breakage upon renaming the file or modifying the headline. This is not the case anymore. Now, we use `org-id` to create IDs for those headlines, which are then stored in our database to compute the relationships and jump around. Note that this will work even if you’re not using `org-id` in your global configuration for Org-mode.

-`org-roam-graph` by default expects to find the `dot` executable
+The `file-truename` function is only necessary when you use symbolic links
-from the `graphviz` package in the `exec-path`.
+inside `org-roam-directory`: Org-roam does not resolve symbolic links.
-Ensure `graphviz` is installed and found if you want to use this
-feature or customize your configuration for `org-roam-graph` to use a
-different tool.
 
-For more detailed installation and configuration instructions (including for
+Org-roam requires sqlite to function. Org-roam optionally uses Graphviz for
-Doom and Spacemacs users), please see [the
+graph-related functionality. It is recommended to install PCRE-enabled ripgrep

-;;; Commentary:
-;;
-;; This library provides `org-roam-doctor', a utility for diagnosing and fixing
-;; Org-roam files. Running `org-roam-doctor' launches a list of checks defined
-;; by `org-roam-doctor--checkers'. Every checker is an instance of
-;; `org-roam-doctor-checker'.
-;;
-;; Each checker is given the Org parse tree (AST), and is expected to return a
-;; list of errors. The checker can also provide "actions" for auto-fixing errors
-;; (see `org-roam-doctor--remove-link' for an example).
-;;
-;; The UX experience is inspired by both org-lint and checkdoc, and their code
-;; is heavily referenced.
