## Introduction and explanation of symbols

Changes are sorted by "type" and then chronologically with the most recent at the top. These symbols denote the various action types:=add, =fix, =remove, =update

## Version 1.0 (July 2010)

### Changes to the End-User API

- Added a command-line option '-catalog' to use a catalog resolver for the XML and XSLT files Committed by SP.

### Changes to the Code Base

- Added support for xmlfile and xsltfile parameters in FOP's Ant Task. Committed by AC.
- Added the possibility to use CachedRenderPagesModel, to conserve memory in case of large documents with a lot of cross-references (area tree will be serialized to disk to avoid keeping it entirely in memory). Committed by AD. Thanks to Dario Laera. See Issue 46828.
- Added an event handling framework which allows to get better feedback from within FOP with the ability to customize problem management. Committed by JM.
- Bugfix: when #CMYK pseudo-profile was used in the rgb-icc() function, always the fallback RGB colors were used instead. Committed by VH. Thanks to Venkat Reddy. See Issue 48167.
- White-space handling in markers with inline-content throws a NullPointerException in some cases. Committed by AD. See Issue 47710.
- Bugfix: previously retrieved markers were not cleared if the new marker was empty. Committed by AD. See Issue 46960.
- Changed meaning of ‘-v’ option to ‘verbose’, which will print FOP’s version and proceed. Added a ‘-version’ option to simply print the version then exit, following Java practices. Committed by VH.
- MinOptMaxUtil.toMinOptMax was converting LengthRangeProperty objects into illegal MinOptMax objects (in some cases opt could be inferior to min). Committed by VH. See Issue 46638.
- Fixed a memory-leak in Marker.MarkerAttribute, where an instance was used both as key and value in a WeakHashMap, effectively neutralizing the benefit of using WeakReferences. Solved by extending PropertyCache to work for MarkerAttributes as well. Committed by AD. See Issue 46319.
- Fixed some multi-threading issues in FontCache.java:
  - remove the unused private readObject()
  - make the changeLock member final (initialization-safety + impossible to reassign)
  - perform the HashMap check for a failed font inside the synchronized block to avoid a race condition
  Committed by AD. Thanks to rogov.AT.devexperts.com. See Issue 46211.
- Make fop.bat and fop.cmd use the %FOP_OPTS% environment variable. Committed by AD. Thanks to Carsten Siedentop. See Issue 45842.
- Quick-fix to avoid a possible NullPointerException when using empty inlines and hyphenation. Committed by AD. See Issue 45667.
- Fixed memory leak in property cache (not cleaning stale PropertyCache$CacheEntry instances). Committed by JM.
- Fixed a slight error when resolving non-file URLs: avoid altering the original 'href' if the protocol is other than 'file:' Committed by AD. Thanks to Thomas Stieler. See Issue 45490.
- Corrected white-space-treatment for situations where an inline-node is the first/last child node of an fo:block, without preceding/following text. Committed by AD. See Issue 45097.
- Fixed a logic error in Hyphenator.java: If the source had an associated InputStream, an UnsupportedOperationException was triggered. Committed by AD. See Issue 44203.
- Changed FONode.addCharacters() parameter to closer match the signature of the standard SAX characters() event (reduces confusion and computations). !! Implementors of extensions that subclass FONode directly, and offer an implementation for addCharacters() should take care to make similar modifications in their code !! Committed by AD.

### Changes to the Bundled Extensions

- Added support for the #CMYK pseudo-profile supported by some commercial XSL implementations on the rgb-icc() function. Committed by JM.

### Changes to the Font Subsystem

- Added support for TrueType fonts with symbol character maps (like "Wingdings" and "Symbol"). Character for these fonts are usually found in the 0xF020 to 0xF0FF range (a Unicode private use area). Committed by JM.
- Added support for specifying referenced fonts per renderer in addition to the general match list. Committed by JM.
- Added a command-line tool to list all configured fonts (org.apache.fop.tools.fontlist.FontListMain). Committed by JM.
- AFP Fonts: Added support for full URI resolution on configured AFP fonts. Committed by JM.
- FOP now creates ToUnicode CMaps for single-byte fonts that don't use built-in encodings to help PDF text extractors interpreting characters. Committed by JM.
- Added support for forcing single-byte encodings for TrueType fonts without creating an XML font metric file (see "encoding-mode" attribute on "font" element) Committed by JM.
- For auto-detected fonts it is now possible to specify that a font needs to be referenced rather than embedded (for the output formats that support this distinction). Committed by JM.
- Add support for font substitution. Committed by AC.
- Added support for auto-configuring TrueType Collections. XML font metrics files for *.ttc fonts are not required anymore. Committed by JM. Thanks to Jason Harrop. See Issue 44737.
- Added support for addressing all glyphs available in a Type 1 font, not just the ones in the font's primary encoding. Committed by JM.
- Bugfix: Font selection fallbacks did not work in some cases (ex. bold+italic to normal) Committed by JM.
- Fixed generation of CIDSet object in PDF output. Committed by JM. Thanks to Nicolas Peninguy. See Issue 47711.
- Bugfix: support PFM Files with no extent table. Committed by CB.
- Bugfix: for the last character of a Type1 font, always a width of 0 was returned. Committed by VH. Thanks to Maxim Wirt. See Issue 47232.
- Use temporary directory for the font cache if the user home directory is not write-accessible. Committed by JM. Thanks to Alok Singh. See Issue 46686.
- More robust AFP font parsing, although it is still in need of some rework in the future. Committed by AC.
- Fix for PFMReader after bug #43089 changed the behavior of PFMFile. Fixes baseline problems when Type 1 fonts are used in conjunction with XML font metric files. Committed by JM. Thanks to J. Frantzius. See Issue 45734.

### Changes to the Image Support

- Added customization ability for the image loading framework from FOP's configuration file. Committed by JM.
- Added support for SVG 1.2 functionality inside fo:instream-foreign-object. Committed by JM. See Issue 41657.

### Changes to the Layout Engine

- Implement internal character classes if the hyphenation pattern file does not contain them Committed by SP.
- Added limited support for pages of different inline-progression-dimensions within a page-sequence. Committed by VH.
- Added basic implementation for column-keeps. Committed by AD. See Issue 46905.
- Added extension to disable column balancing before blocks spanning the whole page, in multiple-column documents. Committed by VH. Thanks to Georg Datterl. See Issue 46315.
- Added missing generation of areas for empty grid units in tables with collapsing border model. Committed by JM.
- Allowing non-zero borders and padding on page regions when relaxed validation is turned on. Committed by LF.
- Implemented word-by-ford font-selection strategy on text. Committed by MB.
- Support character-by-character font-selection strategy on fo:character element. Committed by MB.
- Added minimal support for integer keep values on the various keep properties on block-level FOs. For now, all integer values are treated the same (i.e. without strength distinction). Using integers allows to avoid overflows that can happen when "always" is used extensively. Committed by JM.
- Bugfix: having a special page-master for the last page caused loss of content when normal blocks were mixed with blocks spanning all columns. Committed by VH. See Issue 46486.
- Bugfix: value of conditional space not always taken into account in the calculation of a table’s height. Committed by VH. See Issue 48082.
- Fixed handling of percentage values for provisional-label-separation. Committed by VH.
- Fixed handling of percentage values for provisional-distance-between-starts. Committed by VH. Thanks to Jonathan Levinson. See Issue 47835.

- Bugfix: footnotes occurring within the forced height of a table row did not appear on the output Committed by VH.
- Fixed a bug when combining a forced break with a "last" page-master. The restart of the algorithm would start at the index of the penalty corresponding to the last page-break. This has been changed to the index of the first element after the last page-break. Committed by AD. See Issue 46489.
- Fixed BPD trait and border painting for leaders with leader-pattern="space" (and similar cases). Committed by JM.
- Fixed fo:instream-foreign-object inside fo:marker. Committed by JM. See Issue 45306.
- Fixed a bug when combining break-before with a span change. Committed by AD. See Issue 46240.
- Fixed a problem where the BPD or a block area could be wrong if there is a nested, absolutely positioned area (for example a block-container). Committed by JM.
- Bugzilla 40798: A conditional-page-master-reference with page-position="last" qualifies for a first page, if it is also the last. Additionally: also added support for page-position="only". Committed by AD. See Issue 40798.
- Fixed the source for a division by zero when the content of an fo:leader with leader-pattern="use-content" collapses to zero width during layout. Committed by JM.
- Fixed ID resolution for nested bookmarks with duplicated IDs. Committed by JM.
- Added LayoutManagerMapping.registerMaker() to make registration of custom layout managers easier. Committed by JM. See Issue 45470.
- Fixed absolute positioning of block-containers when specified using right and bottom instead of left and top. Committed by LF.
- Fixed an inconsistency in footnote handling that led to unnecessary empty areas in pages whose last normal line contains footnotes when the page bpd is not the same for all pages. Committed by LF.
- Added support for page-number-citation and page-number-citation-last of fo:inline. Corrected behavior for page-number-citation-last of fo:block: forward references now properly resolved. Committed by AD. See Issue 44794.
- Added support for the "id" attribute on fo:wrappers when used as a child of the fo:flow. Committed by AD. See Issue 42423.
- Fixed a ClassCastException when using an fo:wrapper as a child of an fo:block-container. Committed by AD. See Issue 41500.
- Fixed a regression introduced by the fix for Bugzilla 44286. Committed by AD. See Issue 42703.
- Activated min-height/max-height and min-width/max-width properties. Committed by AD. See Issue 43591.

### Changes to Renderers (Output Formats)

- AFP Output: Added enhanced dithering functionality for images that are converted to bi-level images. Committed by JM.
- Initial support for CID-keyed double-byte fonts (Type 0) in AFP output. Committed by JM. Thanks to Peter Hancock. See Issue 48567.

- PCL Output: Added support for specifying the output bin. Committed by JM.
- AFP Output: Added support for embedding external AFP form maps (form defs) using the afp:include-form-map extension. Committed by JM.

- AFP Renderer Raster Fonts:
  - added support for fractional font-sizes in the configuration.
  - selection of the smaller font-size, in case two possible fallbacks have the same difference to a requested size.
  Committed by AD.
- Added setting to enable dithered painting of filled rectangles in AFP and PCL. Committed by JM.
- Added a custom text painter for rendering SVG text using text operators when rendering to PostScript or EPS. Text is no longer painted as shapes, thus creating much smaller files. Committed by JM. See Issue 47000.
- AFP Output: Tag Logical Element (TLE) is now also allowed on fo:page-sequence (page group level). Committed by JM.
- AFP Output: Added support for Invoke Medium Map (IMM). Committed by JM.

- AFP Output: Native image embedding support (e.g. JPEG, GIF, TIFF) using ObjectContainer and a MOD:CA Registry implementation. Committed by AC.
- Added PDF /Launch action: references to URIs using the file:// protocol will now generate a /Launch action as opposed to a more general /URI (which doesn't yield the expected result for this protocol). Committed by AD. Thanks to Alexander Stamenov. See Issue 45113.
- PDF Output: Added support for handling 16-bit alpha channel. They are currently converted to 8 bits. Committed by JM. See Issue 45795.

- Bugfix: When there was a forced break after a block with (conditional) borders the border-after wasn't painted. Committed by JM. See Issue 44412.
- Bugfix: a forced break inside a cell was ignored when occurring before the minimum height set on the enclosing row was set. Committed by VH.
- Fixed exceptions when lists, tables or block-container are children of an inline-level FO. Committed by JM.
- Fixed the rendering of the area of a table corresponding to border-separation, which must be filled with the background of the table, and not the rows. Committed by VH.

- Bugfix in tables: wrong element generation by the merging algorithm when glues must be produced to cope with conditional spaces. The corresponding length was added twice: one in the glue itself and one in the following box. Committed by VH. See Issue 43712.
- Bugfix: breaks generated by the merging algorithm for a table-row containing empty cells had always a penalty of 900. Committed by VH. See Issue 43766.
- In case of missing cells the border-end of the table was applied to an inner cell, instead of the (empty) cell in the last column. Committed by VH.
- Fixed the resolution of borders with table-columns (border-before/after was wrongly applied to every cell of the column). Committed by VH.
- Fixed the resolution of border-end on cells spanning several rows. Committed by VH. See Issue 42768.
- Bugfix for NPE with empty table-row (regression from 0.93). Committed by JM.
- Fixed swallowing PCDATA in text-node children of retrieved markers. Committed by AD. See Issue 42705.
- Fixed erroneous white-space removal in retrieved markers. Committed by AD. See Issue 42703.
- Fixed erroneous usage of inherited color-values in SVG. Committed by AD. Thanks to ckohrn.at.tng.de. See Issue 43274.
- Facilitate the implementation for font-selection-strategy:
  • Changed FontInfo.fontLookup to always return an array of FontTriplet.
  • Changed CommonFont.getFontState to return an array of FontTriplet.
  • Initial modifications to the related LMs: initialized with the font corresponding to the first of the triplets.
  Committed by AD.
- PropertyCache phase 2:
  • improvement of the PropertyCache itself should now guarantee acceptable performance of the static caches in multi-session environments, which is a possible problem with synchronizedMap.
  • changed CommonFont to use the cache: added CachedCommonFont to contain the properties that are always cacheable CommonFont itself is only cached if the remaining properties are absolutes.
  • changed CommonHyphenation, KeepProperty, ColorProperty and FontFamilyProperty to use the cache.
  Committed by AD.

### Changes to Renderers (Output Formats)

- Added an option to disable the default sRGB profile in PDF output for those who don't care about color fidelity, but care about PDF file size. Committed by JM.
- Added support for the natural language indentifier ("Lang" in the document catalog) for PDF documents based on the language/country values on fo:page-sequence. Committed by JM.

- Fixed generation of named destinations so it works when the PDF document is encrypted. Committed by JM.
- Bugfix: allow multiple bookmarks to point at the same destination. Committed by JM. See Issue 37993.

- Added feature: support for page-break-* shorthands Committed by AD.
- Bugfix: The generation of the PDF "d" (setdash) command was assuming that only integer values can be used but that isn't the case. Dash patterns PDFGraphics2D would be wrong in the process. Committed by JM.

- Bugfix: Fixed an NPE that was thrown when a table was used inside a footnote-body. Committed by JM.
- Bugfix: Fixed a problem with certain TrueType fonts which are missing the "PCLT" table, where a baseline-shift="sub" had no effect due to a missing x-height value. (Note: This only affects TTFReader, so the font metric file has to be regenerated.) Committed by JM.
- Bugfix: When the base URL was specified as a file system path, the constructed URL was wrong. Committed by JM.
- Bugfix: Fixed two causes for ClassCastExceptions in BlockContainerLayoutManager. Committed by JM.
- Bugfix: padding-top and padding-bottom on list-items could lead to wrong page break decisions and thus to overlapping text. Committed by JM.
- Bugfix: break-before and break-after were ignored on list-items. Committed by JM.
- Bugfix: The elements representing a non-breaking space weren't always correct. Committed by LF. See Issue 38507.
- Bugfix: Text-decoration was not promoted if no text-decoration attribute was specified on a nested element. Committed by JM. See Issue 38453.
- Bugfix: Spanned cells could lead to an false error message about overlapping cells and ultimately a NullPointerException. Committed by JM. See Issue 38397.
- Bugfix: Regions with non-standard names got ignored in RTF output leading to missing headers and footers. Committed by JM.
- The RTF output now properly generates the "\landscape" flag for documents in landscape orientation. Committed by JM.
- Following a clarification by the XSL FO SG, space traits are only set on the first and last area generated by an FO, and not on every area anymore. Committed by JM.
- Bugfix: Floating point numbers were not properly formatted in the PDF renderer which could lead to error messages while opening a PDF in Acrobat Reader. Committed by JM.
- Bugfix: Spans that end up with a negative height don't get swallowed anymore. Committed by JM. See Issue 38054.
- Bugfix: Certain border styles could lead to a NullPointerException. Committed by JM. See Issue 38132.
- Bugfix: Space was not adjusted if the space was on a nested block. This could lead to content overflowing the bottom of a page. Committed by JM. See Issue 38102.
- Bugfix: TableCell did not properly report that it generates reference-areas which could lead to wrong inherited values for start-indent and end-indent. Committed by JM.
- Bugfix: Image height for BMP images was incorrectly calculated Committed by MM. See Issue 38089.
- Bugfix: NullPointerException on certain fo:inline within lists. Committed by MM. See Issue 38053.
- Bugfix: ClassCastException on certain fo:inline with border combinations. Committed by MM. See Issue 37743.
- Changed a method name in LineArea from finalize to finalise because it was never intended for the method to be an override of the Java Object finalize method. If invoked by the Java garbage collector it may cause a NPE. Committed by MM.
- Implement property name as default argument on some xsl-function calls. Committed by SP. Thanks to Gerhard Oettl. See Issue 38098.

## Version 0.91beta (23 Dec 2005)

### Changes to the Code Base

- Added checks that warn about tables and block-containers that are wider than the available content area. Committed by JM.
- First attempt at SVG support in RTF output. SVG images are converted to 300dpi JPEG images internally. Committed by JM.
- The command-line now automatically sets two parameters for any XSLT transformation: "fop-output-format" contains the MIME type of the currently selected output format, "fop-version" contains FOP's version number. Committed by JM.
- Added an alternative set of rules for calculating text indents which tries to mimic the behaviour of many commercial FO implementations that chose to break the rules in the FO specification in order to better meet the natural expectations of inexperienced FO users. Committed by JM.
- font-family list still not fully supported but a comma-separated list is now properly tokenized. FOP will now go through all fonts in the list to find one that is available, but it doesn't do so per character, yet. Committed by JM.
- Implemented "Overconstrained Geometry" rules (5.3.4, XSL 1.0) for the most important cases. Committed by JM.
- Support for leader painting in PostScript output. Committed by JM.
- Support for hyphenation-ladder-count. Committed by LF, MM.
- Fixed a bug where the linefeed-treatment property value "preserve" was not honoured when used in conjunction with text-align="center". Committed by MM.
- Bugfix: hard breaks with even-page or odd-page were not handled correctly when spaces were surrounding the break. Committed by JM. See Issue 37964.
- Fixed a bug where SVG content could be clipped when rendered to PostScript. Committed by JM.
- Changed the way resolutions are handled. The single resolution in the user agent got split up into source and target resolutions. For more info, see the updated documentation. Note: backwards-incompatible change! Committed by JM.
- Bugfix: Some content inside a table-header may not have been renderered on pages n > 1 in certain conditions. Committed by JM. See Issue 37875.
- Fixed a bug where an empty line, i.e. a block containing only a &nbsp;, was not rendered at all. Committed by MM.
- Fixed a bug where the area for a finished cell that is broken over pages was created once for each row it was spanned over instead of only once. Committed by JM.
- Bugfix: Footnotes were lost if the footnote appeared in centered text. Committed by JM. See Issue 37880.
- Fix to correct image sizes in RTF output. Committed by JM.
- The output file is now deleted when an exception occurs when calling FOP from the command-line. Committed by JM.
- Bugfix: Areas for table-cells that are broken over more than one page are now generated even if all its content is already painted on a previous page. This fixes strange effects like a table grid that is not completely painted. Committed by JM.
- Bugfix: Column balancing produced strange break decisions in certain multi-column documents with large amounts of text. Committed by JM. See Issue 37828.
- Bugfix: The combination of content-width="scale-to-fit" and content-height="100%" did not work as expected due to a datatype conversion bug. Committed by JM. Thanks to Tom Craddock. See Issue 37815.
- Bugfix: A span="all" on the first block cause a subsequent page break and the first block didn't span all columns. Committed by JM. See Issue 37813.
- Bugfix: Self-created OutputStreams in PNG Renderer were not properly closed. Committed by JM.
- Bugfix: Relatively positioned BlockViewports (from block-containers) caused the paint cursor not be be properly advanced when space-before or space-after were present. Committed by JM.
- Bugfix: Space resolution was incomplete for content in table-cells. Conditional elements didn't get removed. Committed by JM.
- The validation check for non-zero borders and padding on a region-* and for empty static-content elements is now turned off when relaxed validation is active to improve compatibility with FO documents written for other FO implementations. Committed by JM.
- Bugfix for "/ by zero" ArithmeticExceptions when an URL to a non-existing image is used and content-width and/or content-height is used. Committed by JM.
- Bugfix for a multi-threading problem: propertyListTable initialization moved from the constructor to a static block in FONode. This fixes NullPointerExceptions in PropertyList. Committed by JM.
- Bugfix for placement of text inside a text area when borders are present in PostScript output. Committed by JM.
- Deprecated Fop constructors that use integer constants to select the output format have been removed in favor or the constructors that use MIME types. Committed by JM.
- Changed the XMLHandler interface so it doesn't report the MIME type it supports but instead can report whether it supports a particular Renderer implementation. XMLHandlers are now configurable. Committed by JM.
