+You may be familiar with XML-based RSS and Atom feeds from the web. The Gemini equivalent of these is Gemini feeds. A Gemini feed is simply a regular 'text/gemini' page that contains one or more links whose labels are formatted in a particular way. This makes it very easy to write pages that clients can subscribe to.

+Lagrange supports Gemini and Atom feed subscriptions. Atom feeds are  automatically translated to the Gemini feed format so they can be viewed and subscribed to like a normal 'text/gemini' page. RSS feeds are not supported.
+
 Subscriptions are managed via bookmarks. When you subscribe to a feed page, a bookmark is created and the special "subscribed" tag is applied on it. In the Bookmarks list, this is indicated by a ★ icon. There is no other difference between normal bookmarks and feed subscriptions — you may tag any bookmark as "subscribed" and Lagrange will look through it for feed-style links. The bookmark title is used as the feed title. This defaults to the top heading of the feed index page, but you can edit it to suit your needs.
 
 Feeds are refreshed periodically while Lagrange is running, and also immediately after launching if it has been a while since the previous refresh. You may also manually refresh all feeds via the menus or by pressing ${SHIFT+}${CTRL+}R.

However, the custom frame overrides default behaviors of the window, so if you are a Windows power user expect it to not support all the special interactions.

 # Release notes
 
+## 1.2
+
+New features:
+* Atom feed subscriptions: Atom XML documents are automatically converted to Gemini feed index pages. This is a built-in version of the Atom-to-Gemini example on the Help page.
+* Inline downloads: right-click on any link that is openable inside Lagrange and select "Download Linked File".
+* Editable bookmark icons: use your favorite Unicode character as the symbol to represent a bookmarked site.
+* Searching via URL field: non-URL text entered in the field is passed onto the configured search query URL (Preferences > Network). An indicator is shown if a query will take place.
+* Tab auto-reloading: configure a reloading interval using the page context menu ("Set Auto-Reload..."). Auto-reloading is part of the persistent state of the tab.
+* "Iosevka" and "Source Sans Pro" (the UI font) can be used as heading and body fonts.
+* User preference for aligning all pages to the top of the window.
+* Keybinding (F11) for toggling fullscreen mode. On macOS, the shortcut is ⌃⌘F as before.
+* Keybinding for finding text on page.
+
+UI design:
+* Enhanced navbar: adjusted spacing, URL field has a maximum width, tab titles have less pronounced borders.
+* Improved sidebar appearance: bold subheadings, larger feed icons, adjusted spacing, background color.
+* Font consistency: all UI elements use the same font (i.e., no more monospace input fields).
+* Added setting for UI accent color (teal, orange).
+* General fine-tuning of the color palette.
+* Dialog buttons are aligned to the right edge, leaving room for additional action buttons on the left.
+* Page Information button is embedded in the URL field.
+* Page Information dialog is attached to its button.
+* Site icons use a different color in tab titles for visual distinction.
+* Fade background behind modal dialogs.
+* Responsive page margins.
+* Windows: Added a custom window frame to replace the default Windows one. This looks nicer but does not behave exactly like a native window frame. Added a setting to Preferences for switching back to the default frame.
+
+Other changes:
+* Help is opened on first run instead of the "About Lagrange" page to make it easier to discover important Gemini links like the FAQ.
+* "Go to Root" respects a user name found in the URL. One can still "Go to Parent" to get above the user level.
+* Feed entries are sorted by refresh time if they are published on the same date.
+* Don't show future-dated feed entries in Feeds.
+* Middle-clicking on links: open new tab in background or foreground depending on the Shift key.
+* Shift+Insert can be used for pasting clipboard contents into input fields.
+* Removed a strange violet-on-green color theme pairing.
+
+Bug fixes:
+* Fixed text prompt dialogs closing and accepting the entered text when switching focus away from the app.
+* Scroll position remains fixed while horizontally resizing the window or sidebars.
+* Fixed a crash when opening the audio player menu.
+* Fixed Gopher requests that were using URL (percent) encoded characters.
+* Windows: Fixed a flash of white when the window is first opened.
