.. _version_4.9_updates: Version 4.9 Updates /////////////////// 2 Version 4.9.0 `4 <#version-4.9.0>`__ Version 4.9.1 ============= Externally `released `__ on 2017-10-10 - **Tarball:** fixed issue that prevented the 4.9.0 tarball from building Version 4.9.0 ============= * Externally `released `__ on 2017-10-03 * Became metview/new at ECMWF on 2017-10-03 (Linux desktops, ecgate, lxc, lxg, lxop) - **At ECMWF:** - Installed **2017-10-03** - Built with **Magics** `2.34.3 `__ - Built with **ecCodes** `2.5.0 `__ - Built with **ODB_API** version **0.17.3** - Built with **emoslib** `000452 `__ - **Hovmoeller**: added new parameter to the `Hovmoeller View `__ icon: **Time Axis Mode**, which can be **Automatic Forwards**, **Automatic Backwards** or **User**. - **Cross Section**: added the ability to define a cross section line that goes directly over a pole. As an example, to define a line that goes South from lat=0, lon=-8 over the South pole and round to lat=0, lon=172, supply a line definition like this:  [0, -8, -180, -8]  (N,W,S,E). They key points in telling Metview to use a line that goes over a pole are that the longitude remains the same and that the second latitude is described as either greater than 90 or less than -90. The direction of the line is implicit: here, to go from 0 to "-180" involves travelling South. - **Text Plotting**: added new parameter to the `Text Plotting `__ icon: **Text Orientation**, which can take the values **Horizontal** (default), **Top Bottom** and **Bottom Top**. - **Stations**: use the latest WMO stations database - **Stations**: improved the way that station names are matched in the station lookup widget in the Stations editor - **Macro**: new Macro function called :func:`percentile` was added to compute percentiles from a list of vectors
