### What's New in Version 2.15.0 This release makes everything you have written findable: journal search, a Knowledge screen, and a timeline of the dates in your entries. - **Journal search.** Search from the field at the top of your journal. Onsen matches your exact words and your meaning at the same time, so you can find an entry by how it felt when you cannot remember what you wrote. Matching words are highlighted in the results. - **Knowledge.** A new screen holding the people, places, moods, moments and dates from your writing. Each one has its own page showing when it comes up, what it appears alongside, and every entry that mentions it. Rename an item, merge duplicates, or forget it entirely. Your entries are never changed. - **Timeline.** Your entries arranged by the dates they talk about rather than the day you wrote them, from years back to months ahead, each row named for the occasion. Drag the chart above it to move across decades. - **Journal filters.** Filter by favorites, period, guided experience, artwork, or the time of day you were writing, and combine filters freely. Active filters stay visible above your entries. - **Favorites.** Heart an entry to find it again later. Heart a guided experience to save it to its own tab. - **Experience ratings.** Rate a guided experience out of five, with an optional note on what worked. Experience cards show how other people rated them, so you know what has helped others before you start. - **Account screen.** Your entries, experiences, day streak, membership and plan in one place. Account deletion now lists exactly what will be removed and offers you a copy of your data first. - **Also in this release.** A compact journal layout, the time of day on every entry, faster notification clearing, help you can reach before signing in, and new artwork across empty and error screens. Thanks for being part of the journey.
