<release version="2.2.1" date="TBD">
<action dev="jahlborn" type="update">
Implement IsNumeric function. Add support for hex/oct integer
strings.
Implement the majority of the missing standard functions:
FormatCurrency, FormatDateTime, FormatNumber, FormatPercent, Val,
DateAdd, DateDiff, DatePart, MonthName, WeekdayName, DDB, IPmt, PPmt,
Rate, SLN, SYD, Format, Replace, StrConv. (Note that the internal API
for the expr package has changed in an incompatible way. However,
since the API is still experimental, this was deemed acceptable for a
minor version.). Note that many of the financial functions were
copied and adpated from the Apache POI and UCanAccess projects (which
are both under the Apache License 2.0).
</action>
<action dev="jahlborn" type="update">
Implement more type coercion methods for expressions. Add support for
hex/oct integer strings. Add support for number strings with commas.
Add support for coercing numeric String to a date/time value. Add
support for date/time values with implicit (current) year.
</action>
<action dev="jahlborn" type="fix" system="SourceForge2" issue="150">
Ignore column validators for read-only dbs. This will avoid
irrelevant failures when reading databases which have invalid column
properties.
