+      <description>
+        <p>
+          We are proud to announce that 0.G “Gaiman” stable release has arrived! Two years have
+          passed since the release of the stable version 0.F “Frank”, two years of unprecedented
+          turmoil in the real world that delayed our planned release of the next stable. These two
+          years have seen many IRL job changes among the dev team, new contributors to CleverRaven,
+          and a couple of babies joining members' families. The 0.G release is more than double the
+          size of the 0.F release, a distinction that we keep trying and failing to avoid. Even more
+          than previous stable versions, this release features a massive range of bugfixes, code and
+          content additions, and new features. 10,293 new game entities were added, 11,643,312 lines
+          of source code were inserted, and 5,022,361 lines were deleted. This included several new
+          language translations, multiple new tilesets; including some isometric tileset demos, and
+          multiple new mods in addition to base game content and features.
+        </p>
+        <p>
+          This cycle was started, tilting at our perennial windmill of a six to nine month release
+          cycle. Shortly thereafter, Covid locked down the world but not contributions to DDA! There
+          are many incredible changes that have entered the game and several ancient issues that
+          have been closed. The skill system has been greatly expanded with many new proficiencies
+          and many new ways to learn them, as well as the groundwork for practice-based skill
+          improvement, including a skill rust system that doesn't suck because it caps effective
+          skill loss and regenerates faster than regular skill gain. Appliance based stationary
+          power grids now exist. Turning vehicles now present complete walls that block out
+          monsters, fields and more from crossing from the outside to the inside of the vehicle. Map
+          memory is now unlimited, so you will no longer forget places you haven't been to recently.
+          Cardio has finally been modeled so that your endurance will increase if you spend your
+          days running and working hard or exercising. Perspiration is now modeled, your character
+          running around the middle of summer in full plate mail won't immediately overheat. Now
+          your character will perspire and thirst will increase until you are dehydrated at which
+          point overheating will begin. Hydrate yourselves accordingly!
+        </p>
+        <p>
+          In addition to the above issue/request resolving features above, there are a number of new
+          features that haven't necessarily been on the roadmap for a long time but came to fruition
+          during this experimental cycle. The amount of UI based contributions has gone through the
+          roof this cycle and created tons of options around how your fully customizable sidebar
+          looks, the color theme for your UI is also fully customizable with multiple shipped
+          options, along with updates and improvements to action explanations, tutorials and the
+          github process itself, which while not visible to people who only play the game makes a
+          huge difference in the quality and amount of contributions added to Cataclysm: Dark Days
+          Ahead. You can now passively purify water by boiling it by placing it in a fireproof
+          container on a fire or near an extreme heat source. A new hobby tab in character creation
+          allows you to choose traits and skills that go together that represent how you spent your
+          time before the end of the world. Monster weak points now exist, allowing your strikes to
+          critically hit. You can learn proficiencies that will increase your likelihood to
+          critically hit these weak points by researching and dissecting monsters. Speaking of
+          monsters, we've adjusted the aggression system so that some more intelligent monsters will
+          recognize whether they were attacked by another monster or the player and will remain
+          passive or gain hostility depending on who harmed them. A lone zombie will no longer turn
+          a pack of wild dogs permanently hostile to you. Finally, Effect on Condition brings a
+          scripting pseudo language to Cataclysm. Some of its key uses in 0.G have been the
+          introduction of portal storms, NPC faction development over time, the ability to take over
+          a follower after pc death, and random encounters in already explored maps.
+        </p>
+        <p>
+          During this time modders have added a half dozen new in repo mods: Innawoods for the
+          survival from scratch you crave, Backrooms which takes place in the neverending backrooms
+          dimension, Massachusetts mod for people who desire geographic accuracy, Xedra Evolved a
+          science fantasy mod with weird magic and vampirism, Tropicataclysm for your Cataclysm at a
+          warmer latitude, and the Megafauna mod which targets an ancient epoch with creatures that
+          outsize our modern equivalents, similar to Dinomod. In addition to this Magiclysm,
+          Dinomod, and Aftershock have received dozens of new PRs each to a scale that would be
+          equal to or larger than paid DLC for a AAA game.
+        </p>
+        <p>
+          We, the DDA team, have had a great time creating new content and worlds to explore and we
+          hope that you enjoy them and if a mood takes you, that you join us in creating more in the
+          future.
