+## 0.2.5 / 2023-01-18 17:01+01:00
+
+* New
+  * When adding session, pre-select game with the last session
+* Fixed
+  * Start session now button would take up 100% width, leading to accidental clicks (https://git.kucharczyk.xyz/lukas/timetracker/issues/37)
+* Removed
+  * Session model property `last` is already implemented by Django method `last()`, thus it was removed (https://git.kucharczyk.xyz/lukas/timetracker/issues/38)
+
+## 0.2.4 / 2023-01-16 19:39+01:00
+
+* Fixed
+  * When filtering by game, the "Filtering by (...)" text would erroneously list an unrelated platform
+  * Playtime graph would display timeline backwards
+  * Playtime graph with many dates would overlap (https://git.kucharczyk.xyz/lukas/timetracker/issues/34)
+  * Manually added times (= without end timestamp) would make graphs look ugly and noisy (https://git.kucharczyk.xyz/lukas/timetracker/issues/35)
+
+## 0.2.3 / 2023-01-15 23:13+01:00
+
+* Allow filtering by platform and game on session list (https://git.kucharczyk.xyz/lukas/timetracker/issues/32)
+* Order session by newest as preparation for https://git.kucharczyk.xyz/lukas/timetracker/issues/33
+
 ## 0.2.2 / 2023-01-15 17:59+01:00
 
 * Display playtime graph on session list (https://git.kucharczyk.xyz/lukas/timetracker/issues/29)
