[v3.3][] - 2020-06-25
---------------------
### Changes
* Support building static library on Windows
* Support for `fmemopen()` in Windows UWP applications
* Support for `cfg_getopt(cfg, "sub=name|option")`, i.e., get an option
from a sub-section, by Peter Rosin
* Support for `CFGF_MODIFIED` flag, to detect changes to settings
in memory after parsing, by Peter Rosin
* Support for filtering out settings when printing, by Peter Rosin
* Support for dynamic key=value sections with no pre-runtime knowledge
of setting names, useful for environment variables and similar
* Updated German translation, by Chris Leick
### Fixes
* Fix loop-forever bug found by Christian Reitter; a .conf file
containing only "=", will cause even the simplest parser to loop
forever in internal function `cfg_getopt_secidx()`
* Issue #113: Fail to build `strdup()` replacement
* Issue #118: Fix build on Windows, missing `fmemopen()` replacement
* Issue #120: Handle shell and C++ comments with no space separator
* Issue #125: Drop developer debug msg `QSTR: ...`
* Issue #131: Fix `CFG_PTR_CB()` regression, segfaults when, e.g.,
`cfg_free()` is called. Found and fixed by Peter Rosin
* Issue #135: Revert `CFGF_RESET` flag if `cfg_setmulti()` family fail
* Issue #137: Memory leak in `cfg_setopt()` for PTR options
