## Filters

- IDML Filter

  - Complete rewrite of the filter, fixing many problems and changing several behaviors. Warning: files extracted with previous versions of Okapi will no longer merge successfully due to changes in text units and skeleton processing. Resolves issues #544, #497, #302, #378, #293, #259, #245, #471, and #317. Additionally deprecates the filter configuration options “Maximum Spread Size”, “Generate an error when a spread is larger than the specified value”, and “Create new text units on hard returns”.

- ITS Filter

  - The separator for the `annotatorsRef` values is now `'\s'` (white-space) rather than `' '` (ASCII space). Resolves issue #612.

- JSON Filter

  - Fixed issue #410: add an option to toggle whether or not `'/'` is escaped in output.

- OpenXML Filter

  - Fixed issue #503: chart content will now be exposed for translation in Excel and Powerpoint files.
  - Fixed issue #614: fixed a case where text with different styles could be incorrectly merged into a single run.

- XLIFF Filter

  - Fixed issue #110: `CDATA` sections that appear in markup will be preserved.

## Steps
