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.
