Well, a fixed Magog is better for everyone, so thanks : )

ANNOUNCEMENT:
Version 3.8.4 has been released with the following features:

* Added display of and filtering by "Price History" (i.e. permanent change in price)
Note: Available price history goes back only to late May 2014 (since when 11 games have changed their price).
* Changed the defaults for the Display checkboxes to have them all checked (mostly relevant for first-time visitors and people who regularly delete all their cookies)
* Changed the behaviour of the "Set Almost All" button to also uncheck all the "My Fields" Display checkboxes

Dayum! You're really taking this to the next level. Props!

ANNOUNCEMENT:
Version 3.8.5 has been released with the following features:

* Changed the database update schedule to take place four times a day, rather than twice (in preparation for version 4.0.0)

Oh yeah!
But.. just be careful about not summoning the GoGbear ; )

Great news, and awesome work. You lead!

Uuh, I like this!
Moar automation

I'm more and more impressed by the pace the MaGog is evolving. Awesome job, mrkgnao! :-)

Thank you for all your tireless work on MaGog, mrkgnao.

ANNOUNCEMENT:
Version 4.0.1 has been released with the following features:
* Added sorting by "latest file change date"
* Redesigned the "downloadable files" filters to offer more search flexibility


Examples of searches now possible:
1) Games that have had at least one file change since 1/1/15 (sorted by descending order of latest file change date):

2) Games that have had at least one windows installer or patch or bonus change since 1/1/15 (i.e. not mac or linux):

3) Games that have had at least one linux installer/tarball change since 1/1/15:

Caveat: All these apply, of course, only to games I own.

Cheers, this will come very handy.

Uber cool!
+1 even if your rep grows way too slowly.
(shame on you GOGgers!)


By the way, can you also add these options in the future? (unless I missed them now)

- search games that lost (or gained) some patch\bonuses (changed file number)
- show only modified files for my wanted languages (ex: eng + ita)
- highlight the differences (because I've no idea of what has changed)

Thank you for the kind words.

As for your suggestions:
1) What you ask for is for MaGog to maintain a history for each file in each game (when was a file added/removed), which given the number of games and files will quickly become unmanageable. I will record changes/additions/deletions in the "what did just update?" thread, but MaGog will not remember them. MaGog only stores the current state. The only time-related information I have is what GOG offers, which is file modification date/time (also covers file addition). Thus, when you search for file changes since a given date it also covers file additions (no way to differentiate the two because GOG does not offer file creation time, only file modification time). At the moment, I do not plan to remember files deleted (there are a lot of those, e.g. patches).

2) It's in the plans, I just need to figure out how to do it. Note that a lot of files (e.g. bonuses, patches, tarballs) do not carry proper language identification, so you will probably want to select "Eng + Ita + No Specific Language" when it comes to it.

3) At the moment, the simplest is to change the "Downloadable File Order" option (above the "Tutorial" button) from the default "GOG Order" to "Modification Date". This changes the order of files within a game so that they are sorted from newest to oldest. Thus, the first ones are the ones the changed most recently and are the ones you are probably interested in. Try it. If you find it lacking, I'll consider adding highlighting the files that match one's search criterion.

1) ah no ok, nevermind, I thought that you were just comparing files at each db update between new and old data.

2) perfect. Anyway, files without language spec are probably english here.
Ah, if you can, let us exclude unwanted systems too. (ex: mac)

3) works fine, ty.
However, could you please change the files' color to something less "alarming" than red? For example blue :P
Don't color dates, instead, unless you're going to use a different one.
