Clement Lefebvre ha annunciato il rilascio della preview di Cinnamon 2.8, la nuova versione dell'ambiente desktop sviluppato in casa Mint nato come fork di GNOME Shell.
Questa versione preliminare è rivolta a tutti quegli utenti interessanti a fare da beta tester e a segnalare eventuali bug al team di sviluppo. 
Il rilascio della versione stabile è previsto per la fine del mese di Ottobre 2015 quindi, se non volete andare incontro ad eventuali bug, potete tranquillamente aspettare il rilascio della versione stabile visto che manca davvero poco.
Per installare la preview di Cinnamon 2.8 su Linux Mint 17.2 "Rafaela" o LMDE 2 "Betsy" vi basterà lanciare Sorgenti software e abilitare la voce "Pacchetti non stabili (romeo)".


Una volta fatto vi basterà lanciare il Gestore aggiornamenti di Linux Mint e aggiornare il sistema (non vi posto lo screen perché l'ho già fatto :D).
Per i più curiosi ecco il changelog completo

What’s new in Cinnamon 2.8
We’ll go through the new features and illustrate them with screenshots at the end of the month when it’s time for an official release.

  * Prefs: Rephrase quickrename option
  * nemo-action-config-widget.c: Localize non-localized comment string
  * Updated pot file
  [ Corbin ]

Both 180ms and 300ms seem slow when trying to identify windows by their thumbs, but 180ms gets in the way and shows shadow-thumbs when pressing Alt at “normal” speed. It’s all empirical/subjective really.. but this seems to improve things a bit.

  [ JosephMcc ]
  * Deprecations: Remove use of deprecated g_type_init () and bump GObject requirement accordingly.
  * Deprecations: Replace gtk_icon_info_free() with g_object_unref()
  * Cleanup: instead of attempting to clean up deprecated functionality in cinnamon-arrow, just remove it since it seems to be unused.
  * Cleanup: Fix an unused function warning in cinnamon-global.c
  * Cleanup: Remove st-tooltip. It’s the source of a lot of build warnings and we no longer use it.
  * js: Explicitly dispose of all cairo contexts. A long read on why you want to do this here: https://bugzilla.gnome.org/show_bug.cgi?id=685513

  * Set the X-Gnome-AutoRestart hint to false. Stumbled across this in an old gnome bug report. Fixes the issue with Cinnamon restarting twice with cinnamon –replace
  * windowManager: Destroy the tile hud/preview when we are done with it. Currently after showing the preview you will get a noticeable slowdown when moving windows that pass off the monitor edges. This should help solve that.
  * popupMenu: Add back the expander arrow on PopupSubMenuMenuItem but with a different layout. Also tweak the layout of a couple of our applet menus to look nicer with this change. The addition of the icons to Cinnamon itself is a workaround for Mint. Newer versions of the gnome icon theme have these as built in icons but not in the version supplied with Mint 17. They can be removed in the future.
  * bg: add “spanned” to the list of bg types that need to show the background color options
  * popupMenu: add back a couple checks for the existence of submenu expander arrow to prevent breaking the right click context menus in the menu applet
  * use the new meta_screen_get_current_monitor() to place appswitchers and modal dialogs on the proper monitor in multiple monitor setups
  * workspace-applet: properly dispose a cairo context
  * cs_windows: Reword a setting to match https://github.com/linuxmint/muffin/pull/204
  * windowManager: Make the window dimming effect with attached dialogs a bit stronger and more obvious
  * windowManager: Properly declare a variable
  * add new slider and separator objects
  * workspace-switcher: Rework the visual style workspace switcher so it can be themed. Also fix some st_theme_node warnings and stop windows from being able to be drawn outside the workspace background
  * cs_startup: set modal to true for both the “Choose application” and “Add custom command” dialogs so the behavior is the same for both when using attached dialogs
  * rework the window list and effects so minimize effects work properly with multiple window lists on multiple monitors
  * sound-applet: make the volume slider for individual applications fully expand
  * workspace-swithcer: Use the set_important() function to make sure we get proper theming on the visual workspace switcher in themes that don’t yet support it
  * systray-applet: fix an undeclared variable warning
  * theme: Re-style and size checkboxes and radio buttons in the default theme
  [ leigh123linux ]

  * missed one
  [ lestcape ]
  * Be more selective when filter the mouse release events.
  * Add support for indicators.
  * Fix missing or improperly imports.
  * Moved the indicator to the main cinnamon class. Removed the NameWatchDog Class. Added some checks, and the compatibility with this new behavior.
  * Removed also the NameWatchDog declaration (was omitted in the previous commit).
  * Inhibit the indicator icon, when has a draggable parent.
  * As a pedro recommendation, this is an attempt to move the RadioButton and CheckBox classes to the corresponding place, and reuse it, in the same place.
  * Fixed an error in the regretion from signalManager.
  [ Marga Manterola ]
  * Optimize rebuilding of media-keys hotkeys (fixes #4691)
  * Reorder setting delay_setup_started variable to avoid possible races (improves #4692)
  [ Matthew Petroff ]
  * Restore time remaining option for power applet.
  * Fix translation strings.
  [ Michael Webster ]
  * cs_backgrounds: add missing import
  * window-list applet: restore 2.4 behavior where a window list item demanding attention remains highlighted after it’s done flashing.
  * panel-launcher: Use a generic icon when creating a new launcher, if the user didn’t select a custom icon.
  * st-widget: Expand the “important” property: add set/get methods, remove CONSTRUCT_ONLY flag, have a theme node recalculation triggered when the property changes.
  * capi.py:  Move with rest of cinnamon-settings files to their new location, remove debian sed rule for multiarch fix, instead figure out the right location in the capi code.  Cinnamon-bluetooth is not MultiarchSpec compliant, so we still need to *also* load from /usr/lib/*.
  * st-widget.c: Fix typo in st_widget_recompute_style
  * st-theme-node: properly recalc the theme node when an StWidget’s important property changes.
  * main.js: Fix typo from 08474a03cd660bb176d5ebb361a01ff6d51162fc
  * tooltips.js: Fix some occasional log warnings
  * window list: don’t delay showing a preview, if another preview was just showing.
  * keybindings.js: don’t tell muffin to remove a keybinding that we never set.  This quiets warnings during startup about magnifier hotkeys.
  [ Phillip Berndt ]
  * Calendar applet: Avoid unnecessary wakeups
  * Calendar applet: Update each second if global time format is set to include seconds
  * Calendar applet: Update if Date&Time configuration has changed

  * Also translate xlet metadata in about dialogs
  * cs-backgrounds: add revealer to gradient widgets when picture-options is set to a value where those have no effect
  * Network applet: hide the switch if the switch has got no function   This is typically the case e.g. when a cable is unplugged
  * trash applet: do not add items to context menu on orientation changed
  * extension.js: Use a macro function to create the Extension.Type members
  * extension.js: xlet uuids are unique for each xlet type, it is now possible to have more than one xlet of different types and the same uuid – Extension.unloadExtension, Extension.forgetExtension and Extension.get_max_instances needs to have a type argument after the uuid – Extension.importObjects, Extension.objects, Extension.meta, Extension.dirs are moved to Extension.Type[type].maps[mapType]
  * Automatically reload xlets when updating them instead of showing an info dialog
  * extension.js: Enable imports in a xlet via import.xlet (where xlet is the type of xlet; applet, desklet, extension or search_provider) cinnamon-js.cpp: Removed cinnamon_js_add_extension_importer
  * appletManager: In arrow filter functions, check if the value exists (when iterating over appletObj) Fixed the bug when the button in applet settings has no effect
  [ Rob Adams ]
  * Show audio device name (origin) in sound applet
  * Change calls to highlight, activate callbacks on xlets – Fixed initial instance not being selected on multi-instance xlets (error on highlight) – Passing uuid and instance_id to cinnamon via dbus – instance_id is the same as uuid when multi-instance not allowed – Corrected order of instance tabs in Gtk.Notebook to reflect order instances were added in
  [ Stephen Collins ]
