Release Notes
Changes
------------
The most notable changes in this release are:
* A "lite" version of ooxml-schemas-1.0.jar called
poi-ooxml-schemas-3.6-20091214.jar is included in the binary
distribution. This jar replaces the big ooxml-schemas-1.0.jar in the binary distributions and Maven POMs. The
poi-ooxml-schemas jar is 10 MB smaller!
* Significant memory improvements in XSSF module. When generating data, new
code consumes 200% less memory than POI-3.5.
* Full support for cell comments in XSSF.
* Formula performance and coverage.
Lazy evaluation of formulas has been implemented which provides for
improvements of 700% in some cases.
Your results may vary.
* Examples are now included.
poi-examples-3.6-20091214.jar includes all of the examples from the poi,
poi-scratchpad and poi-ooxml modules.
Users have requested this several times. These examples provide excellent
templates for POI based applications.
Several convertors are included: XLSX2CSV, XLS2CSVmra, BigGridDemo, PPT2PNG,
Word2Forrest, and msg2txt.
* Maven distribution now includes sources.
Each individual JAR is accompanied by a -sources.jar. Two new maven modules
were added poi-ooxml-schemas and poi-examples.
* Program elements intended for POI internal use only are annotated @Internal.
These may be removed or access changed from 'public' to 'default' or less in
future versions of POI.
