- chartsheets are now stored as sheets with "!type" set to "chart"
- fixed Strict XML Workbook Relationships
- stubbed support for dialog and macro sheets
- removed legacy XLS `!range` field
- parsexmltag and other hot functions now better optimized for v8
- monomorphic functions (different types -> different funcs)
- more efficient decode_range implementation when source is trusted
- regular expressions cached and simplified without breaking correctness
- more efficient utf8 techniques when available
- XLSX: large functions broken down into sub-functions (e.g. `parse_ws_xml`)
- XLSB: avoid unnecessary binds
- XLSB: assume no exotic codepage exists (no one else tries to write XLSB)
- demo exposes rABS / worker / transferable options
- more tests
- jszip updated to 2.3.0
- SSF updated to 0.8.1
- codepage updated to 1.3.1
- eliminated functional constructs in hot functions
- format try-catch block extracted into new function
- cpexcel + codepage updated to 1.2.0
- more efficient (and correct) clean implementation of RGB/HSL/tint algorithms
- xlsx binary --all option enables every extra formatting and saving option
- column widths parsed and saved (requires cellStyles:true)
