CHANGES AND BUGFIXES

 0.1 -> 0.2: (19.06.2014)

	or via the config.properties file

0.2.1:

0.3.2: (23.07.2014)
-> Applying the font-styles now behaves different: font-size and kerning of 0 and an empty font-family  
	are NOT applied to sub-elements to avoid erasing this information!
 	NOTE: boolean values (serif yes/no, monospace yes/no, bold yes/no etc.) are still applied
 	 to each level and thus the original information gets erased!
-> Different apply buttons for structure and text-styles

0.4:
-> Indexed tagging and general custom tags

0.4.1:

-> added text undo/redo in transcription widgets
-> Integrated XML source file viewer now has search functionality

0.4.6:
-> Changes over multiple lines should now be possible in the line transcription widget and behave as such:
	- if the number of lines inserted is greater than the number of affected lines (i.e. the marked lines), 
		the excessive newline characters are replaced with whitespaces to guarentee insertion of the whole text 
	- if the number of lines inserted is less than the number of affected lines, the remaining affected lines will be cleared
-> Removed bug that selected parent region after any edit operation
-> Fixed another memory leak problem
-> Added login info (username & server) in doc-overview tab

0.4.7:

-> Some urgent bugfixes: 
	* Deleting words in word transcription editor not possible
	* Tagging / text style adding was buggy too
	* concurrent modification exceptions in doc view
-> Save dialog appears on exit if unsaved changes exist
-> first version of PDF export feature (via acrobat button on top toolbar)
-> Auto update search feature

0.4.8:
	-> Sorting functionality in doc overview
	-> doc overview: do not show public documents
	-> Program updater can overwrite config files
	-> Install a specific version of the tool via Menu->Install a specific version...
	
0.4.9:
	-> Reading order editing via the "Structure" view. 
		* Note: Once a reading order is defined inside a page / region / line, the elements get sorted  by this reading order first and then the coordinates!
		* You can auto-set the reading order according to the coordinates using the respective buttons in the "Structure" tab
		* The reading order is implemented on shape level via a custom tag called "readingOrder" with an integer value that determines the order.
		* If the reading order is equal for two shapes at a certain level, shapes are sorted by their coordinates.
		* If a reading order is set for some shape and not set for the other, the shape with the reading order comes first.
		* When saving the file a reading order on region level is also saved to the corresponding PAGE XML element ('ReadingOrder').
		Reading orders on other levels (lines / words) are not saved in this way, since the file cannot be loaded with Alethia anymore. 
		* Also, a reading order on region level set by the Alethia tool is synchronized with the custom tags on a page load.
		
	-> Adding of baselines, lines and words without their parent region -> if the parent region is not found, 
	the user is asked if he wants to automatically add the corresponding parent region.
	There is also a new toggle button (square shape with a plus) that when toggled disables this question.
	The corresponding property in the config.properties file is 'autoCreateParent'.
	
	-> Drag-and-Drop support in the "Structure" tab: elements can be moved from one parent to another via drag and drop, 
		i.e: lines can be moved to another region, words can be moved to another line.
		The drop has to be performed *onto* a region / line
		Note: it is not checked, whether the new parent region geometrically overlaps its new children -> use this option with care!
		
	-> Pasting multiple lines in the line transcription editor now fills up empty lines after the selection index if possible
	
0.5.0:
	-> Bugfixes (as always...)
	-> Finish a shape on doubleclick
	-> Polyrectangles (instead of just rectangles) are automatically created as parent shapes for baselines

	-> on upload of document you can now specify the collection to upload to; if no collection with necessary rights exists, you can create one
	-> changing name of collections possible
	(-> resolved nasty "invisible top toolbar on window resize in windows when document loaded" bug - hopefully...)

0.5.9:
	-> introudced options item in canvas toolbar (wrench symbol) -> summarizes all options for drawing new elements

	-> PDF import: path for temporary files is now correctly built in Linux
	-> bug fix: closing export dialog immediately after opening caused an exception (widget disposed)
	-> config.properties logHttp setting: enable to get full INFO level HTTP traffic log in console and log file 
	-> implement scrollbar mode for canvas and set it to default scrolling mode 
	-> convert from tables to simple textregions for all cells without losing lines and their transcriptions (via "Metadata->Structural" tab)
	-> CITlab HTR+ basic integration

	-> 'Compare Text Differences Tool' does not block, and (if wished) it shows the line numbering like the text editor
	-> Automatic saving tool: Stores transcript of a page from time to time locally to the user directory. If user loads a remote page it checks if a local version exists and if it is newer then the version on the server - if so it can be stored to the server. Settings can be made via the 'Save button' drop down menu.
	-> Option to change the reading order for all subsequent shapes as well, e.g. ro '35' changes to '3', afterwards '36' to '4', '37' to '5', '38' to '6' till the end of the shape list with the same parent.

	-> bugfix: editing pagination in the document manager dialog could lead to errors in the following save operations 
	-> PDF export: PDFs are much smaller now! for binarized images choosing 'Original' as image type delivers the smallest size, in most other cases 'JPEG'
	-> add collection doclist export as CSV (via green arrow-down button in the doclist toolbar)
	-> main menu: user can choose to load last modified document in Transkribus at start time
	-> HTR model lists are now all represented as tree or table widget pagination
	-> Undo a job (see the 'Jobs Overview': 'Undo button' will be enabled if the docID of the job corresponds to the ID of the currently loaded document)
	-> Documents moved to the recycle bin are automatically discarded after two weeks
	-> New cool feature ;) can be found here: 'Canvas tool bar' - 'Other segmentation tools' - 'Copy shapes to other pages': after the user has drawn tables or text regions he wants to copy this table/text regions for all the other pages as well because they look pretty much the same
	-> And another one: same same but different: 'Canvas tool bar' - 'Other segmentation tools' - 'Remove small text lines': deletes lines which are very small in relation to their region - needs to be used carefully and checked afterwards
	-> Last but not least in this series: 'Canvas tool bar' - 'Other segmentation tools' - 'Merge small text lines': automatically merges small text lines in the same row (should be used carefully)
