It looks like a nasty bug slipped through and made it to the first public release. You should now be able to view and change the unit words again.

You can now again use more than one (!CD#) tag in your name or message.

The ToolTip class has been completely rewritten in a much more object-oriented way. Loading, updating and destroying tooltips should be much faster now because of the implementation of shared tooltip instances.

Thanks to SmokingCookie, a problem with deeply nested submenus and bitmaps was found, which required a revision of the whole class. Developers can now add bitmaps on both menu items and submenus without the need of changing anything to make their old code work with the new class.

Since version 2.1, users can use as many tags as they want. Now, starting from this build, this also applies to the countdowns! That means that you can give your countdowns a recognisable name and create and use as many countdowns as you like. Countdowns have a unique numeric identifier which you should use in the (!CD#) format, the best way to understand is by using the "Insert Countdown" button in the Places tab.

Since the introduction of grouped units in tags in version 2.1.009, the possibilities have increased dramatically. However, simply dropping empty units still didn't provide the necessary flexibility to make any countdown tag. With conditional tags, this is a thing of the past: you can now make your own conditions and even have "if...else"-like unit groups.
Example: { m>2 ?Another %m %mw:Only %m %mw} to go.
Result: Another 5 months to go.
or Only 1 month to go.

You can now configure hotkeys to enable, disable or toggle your countdowns with a simple key combination. These are disabled by default so new users don't press them accidentally, you can find them in the new Hotkeys tab.

As suggested by Geo, you can now choose to change your display picture when a countdown ends. This feature is also reflected in the live preview, where your real display picture is displayed rather than the default blue Messenger buddy. Cool, uh?

This version comes with a new window where you can browse through the online documentation of Countdown Live. The browser has back and forward buttons and a tree structure to navigate. The documentation is completely translatable, so anyone who wants to give this a go and translate the whole set of documentations, feel free to contact me for details.

From know on, you'll be notified when a language file you've installed has been updated on the server. A toast will display at start-up when new updates for your incompatible language files are available, clicking this toast will instantly open the Download Languages window. If you rather don't want these notifications, you can always disable it from the Language Preferences window.

Once again, the countdown calculation algorithm has been revised. This time, I found a much simpler method in Java and I succeeded in rewriting it to JScript. Simpler code is always better, and it appears that this also applies for my code. Hopefully this is the end of a long period of headaches for both myself and all you Countdown Live users!

The rounded rectangle behind the documentation browser didn't stretch vertically, this is now fixed.

Warning: technical stuff follows.
In previous versions, dates were stored as a literal string (REG_SZ) because they exceed the maximum value of a double-word (REG_DWORD). Since this version, they are quadruple words (REG_QWORD) which allow 64-bit numbers to be stored. This method is much more efficient since a QWORD takes up 8 bytes whereas a Unicode string takes up 2 bytes per character, although I did it mainly because it makes things easier for me and because I can! :-D

Some changes were made in the way the cached preferences are saved to the registry for some more flexibility.

Thanks to the great work of the translation team, the Finnish, Greek and French translations are done and included in this release. The German, Italian and Spanish translations will be available in the languages database as soon as I get them from the responsible translators.

The Plus! XML Translator has been updated and a simple conversion of your 2.1.016 translation using the new differences file will upgrade your translation without any problems.

The auto-updater of Countdown Live itself has been removed, as it is no longer needed. Users will need version 4.70 of Messenger Plus! Live or above to use the updater.

Thanks to Phazeus, a bug was found and fixed with the calculation of months when the dates difference was less than one month.

Because of one operator being a little bit faulty (">" instead of ">="), the Plus! version checker gave an error when the current and minimum versions were equal.

It seems that I forgot to change the maximum version for the preferences importing compatibility range. This was the cause of not being able to import preferences from 2.1 in 2.1. I rewrote the system a bit so that these settings, along with the recommended Plus! version, are now stored in the ScriptInfo file itself. Thanks to SmokingCookie for reporting this bug!

The whole system for countdown tags has been revised. Instead of having 2 text fields for both countdowns to enter the tag in, you can make as many tags as you want and use them in multiple countdowns through a drop-down list which replaces the text field. New features for tags required this change, so go and check out the new Tags tab in the Preferences window!

You can now skip units in a tag. This means that the next unit will inherit the value of the selected unit and that the value of this unit will be set to zero. If you don't want to do this manually, you can choose to automatically skip unused units. This will make Countdown Live check the tag first to look for unused units and skip those units.

Finally I implemented something which many users requested! When you enable this feature for a tag, you can group text and units together and make them disappear when the grouped unit's value turns zero. When you use this properly, you can make really nice countdown tags!
Examples:
Tag: My first exam starts in {th:{d:%d %dw, }%h %hw and }%n %nw!
-> My first exam starts in 5 days, 2 hours and 10 minutes!
-> My first exam starts in 1 day, 0 hours and 15 minutes!
-> My first exam starts in 14 hours!
-> My first exam starts in 30 minutes!

All single units now have a matching unit with one leading zero when the value is smaller than 10. This can be handy if you want to make some sort of clock-like countdown, for example.

The preview panel has been extended, with some new features to make it more functional. The preview is now 29 pixels higher, with the contact list toolbar beneath it to carry some new buttons. The countdowns state is now a button to toggle the status, there's a button to force a refresh of the preview and a button to go to the preview settings tab (see further).

A new tab has been added, containing feature options related to the preview panel. Currently, there are two options, make sure you check it out!

With the addition of the weeks unit, all possible time units which are worth adding are available in the script.

Finally I found something to get rid of the need of making the preferences window wider everytime I'm in need of adding a new tab. From now on, Countdown Live will limit the amount of shown tabs based on the window's width and scroll through them with the arrow buttons at the left and right side. You can now also navigate through the tabs with Ctrl+Left and Ctrl+Right.

Because the function for the "Exported on" date in the header comment was replaced in build 2.1.010, the exporting failed. This has now been fixed.

The framework didn't work as good as I wanted, so I merged the required functions from the various source files into a script file and did some modifications myself. Because of this strucural change, the DateJS-Format.js file will be deleted when you install this version.

Another thing which was broken because of earlier changes. The countdown tags (!CD1) and (!CD2) now work properly again in the chat windows.

Not that anyone is going to use this, but hey, you never know! Example: %td0 %tdw may give you 08 days.

Because loading the windows can take some time (especially the Preferences window), they will now start invisible and will be made visible after everything is loaded. So, don't go mad when the window doesn't open immediately on your Quad Core with 4 gigs of RAM. =P

Everything happening with the countdowns is now sent to Plus!' Event Log. This was added because the user could disable the toasts and thus won't be able to know what happened. Now, he/she can look in the Event Log and find it.

Just in time, a glitch was spotted when using the total amount units. This was caused by the fact that the same Date object was used as for the separate units which substracts the timezone offset, while this shouldn't happen for the total amount units. So now, that's been fixed.

Requested by Matty who needed a reliable class for handling list-view controls, I wrote a ListView class which gives more control over list-view controls. Because I felt like Countdown Live should benefit from this too, I implemented it in the current script. And it works great! For example, when the new version of Messenger Plus! Live will be released, users can sort the language files in the "Download languages" window. No more messy workarounds anymore with "Array.sort()", only pure Win32 API! :-D

When Countdown Live starts up for the first time for a new user, it'll try to get the user's Plus! Live language from the languages folder or, if not found there, from the languages server. The user won't notice this action and if this fails, the scripts falls back on the English language file. In a future release, I might even add a language updater... maybe...

At last I found a French translator for the script. A friend of mine asked his French friend Franck Dethier if he was interested in translating the script. He did a fast and great job translating the script, which allows me to release the script on this April Fools day. The other translations are also updated to support the new features since 2.0.006.
