 ## [Unreleased]
+### Changed
+- Updated [go-gemini](https://github.com/makeworld-the-better-one/go-gemini) to v0.9.1 to support CN-only wildcard certs
+- Preformatted text is now grey by default
+
+
+## [1.6.0] - 2020-11-04
 ### Added
+- **Support client certificates** through config (#112)
 - `ansi` config setting, to disable ANSI colors in pages (#79, #86)
 - Edit current URL with <kbd>e</kbd> (#87)
 - If `emoji_favicons` is enabled, new bookmarks will have the domain's favicon prepended (#69, #90)
 - The `BROWSER` env var is now also checked when opening web links on Unix (#93)
+- More accurate error messages based on server response code

 ### Changed
 - Disabling the `color` config setting also disables ANSI colors in pages (#79, #86)
 - Updated [go-isemoji](https://github.com/makeworld-the-better-one/go-isemoji) to v1.1.0 to support Emoji 13.1 for favicons
 - The web browser code doesn't check for Xorg anymore, just display variables (#93)
 - Bookmarks can be made to non-gemini URLs (#94)
+- Remove pointless directory fallbacks (#101)
+- Don't load page from cache when redirected to it (#114)

@ -138,10 +138,19 @@ The config file is written in the intuitive [TOML](https://github.com/toml-lang/

 On Windows, the file is in `%APPDATA%\amfora\config.toml`, which usually expands to `C:\Users\<username>\AppData\Roaming\amfora\config.toml`.

+## Client Certificates
+
+Amfora has early support for client certs. Eventually Amfora will be able to generate them itself, but for you can do it by using OpenSSL:
+
+```shell
+openssl req -new -subj "/CN=username" -x509 -newkey ec -pkeyopt ec_paramgen_curve:prime256v1 -days 1825 -nodes -out cert.pem -keyout key.pem
+```
+
+This will create a certificate and key file, that can be renamed and moved as you like. See the configuration section above for how to edit your config file to tell Amfora about them.
+
 ## Known Bugs

 - Pasting on Windows is truncated, the full paste content won't be added. ([#43](https://github.com/makeworld-the-better-one/amfora/issues/43))
- ANSI codes aren't displaying properly ([#59](https://github.com/makeworld-the-better-one/amfora/issues/59))
