+  - Preliminary high DPI support

+  - Merged patches and fixed other warnings on OpenBSD
+  - Task, Button, Executor: add a bit of slack in the pango text layout,

+    `task_align = right` (issue #688)

+  - Text elements compute their size correctly (issue #671)
+  - Window order persists on panel restart (issue #615)
+
+2017-09-08 15.1
+- Fixes:
+  - Fixed build on non-Linux and non-x86 systems
+
+2017-09-02 15.0
+- Fixes:
+  - Clock, executors and other timers fire correctly after waking up from suspend
+  - One-shot timers are restarted correctly from their own callbacks
+  - Clock is refreshed with better accuracy (thanks @aaaz)
+  - Panel: by popular demand, the old struts behavior with autohide has been restored (issue #619);
+    if you encounter applications that interact poorly with it,
+	you might have better luck with strut_policy = minimum,
+	if that does not work, you will have to turn off autohide.
+- Enhancements:
+  - Panel:
+    - _NET_WM_PID is set correctly, so now tint2 can be interacted with more easily from wmctrl and similar apps
+  - Taskbar: new config option taskbar_hide_different_desktop
+  - Battery:
+    - New config option bat1_format and bat2_format
+	- New config option battery_full_cmd
+	- Better "Unknown" state handling
+  - Executor:
+    - Hide if output is empty
+    - If no user tooltip is set, displays the script standard error as tooltip.
+      Tooltip is multiline, can be cleared with the VT100 clear screen sequence, in shell: (>&2 echo -en "\033[2J").
+      Long tooltips are truncated to 4096 characters.
+  - Launcher:
+    - Drag and drop now handles correctly text/uri-list
+    - Support for Terminal=true
+    - Support for %f and %F
+- Configuration changes:
+  - Removed primary_monitor_first as it was conflicting with taskbar behavior; use *_monitor = primary instead.
+- Other:
+  - Major code refactoring
+- Dropping "0." from the version number and no longer using semver ("Breaking.Feature.Fix").
+  - Tint2 will always strive to be backwards compatible with respect to the configuration format.
+  - Very few configurations changes have been broken between 2010 (0.10) - 2017 (0.14);
+    in all cases they were minor options that caused incorrect behavior,
+    and the changes were described better by "Feature" or "Fix".
+  - Practically all releases starting from 0.10 have been very stable,
+    so there is no point in staying in "0." anymore.
+  - But I don't want the project to get stuck in "1." forever.
+  - The new versioning scheme is the following:
+    - Version numbers will have the format "Feature.Fix", where:
+      - "Feature" is increased when significant new features are added.
+      - "Fix" is increased for bugfixes or minor changes.
+    - 0.14.6 will be followed by 15.0.
+
+2017-06-11 0.14.6
+- Fixes:
+  - Take into account border width when computing text height
+  - Taskbar: Fix task icon size limits
+  - Executor: Do not output last line if it is not terminated by newline
+- Enhancements:
+  - Re-execute tint2 on SIGUSR2.
+    This is useful for preserving config options and environment when updating tint2.
+
+2017-05-21 0.14.5
+- Fixes:
+  - Fixed a couple of memory leaks
+
+2017-04-29 0.14.4
+- Fixes:
+  - Fix regression in executor (issue #639)
+  - Fix crash when _NET_WM_ICON is set but empty (https://github.com/jmc-88/tint3/issues/21)
+
+2017-04-23 0.14.3
+- Fixes:
+  - Make versioning more robust when building as package
+- Enhancements:
+  - Tint2conf: Open current tint2 config automatically when started from tint2
+
+2017-03-26 0.14.1

 tint2 - lightweight panel/taskbar

 ## DESCRIPTION
 tint2 is a simple panel/taskbar made for modern X window managers.
 It was specifically made for Openbox but it should also work with other window managers (GNOME, KDE, XFCE etc.).

+Description: lightweight taskbar
+ Tint is a simple panel/taskbar intentionally made for openbox3, but should
+ also work with other window managers. The taskbar includes transparency and
+ color settings for the font, icons, border, and background. It also supports
+ multihead setups, customized mouse actions, and a built-in clock. Tint was
+ originally based on ttm code. Since then, support has also been added
+ for a battery monitor and system tray.
+ .
+ The goal is to keep a clean and unintrusive look with lightweight code and
+ compliance with freedesktop specification.
