66API Changes
77~~~~~~~~~~~
8- *
8+ * `pvsystem.v_from_i ` and `pvsystem.i_from_v ` functions now accept
9+ resistance_series = 0 and/or resistance_shunt = numpy.inf as inputs
10+ (:issue: `340 `)
11+
12+ Enhancements
13+ ~~~~~~~~~~~~
14+ * Improve clearsky.lookup_linke_turbidity speed. (:issue: `368 `)
15+ * Ideal devices supported in single diode model, e.g.,
16+ resistance_series = 0 and/or resistance_shunt = numpy.inf (:issue: `340 `)
17+ * `pvsystem.v_from_i ` and `pvsystem.i_from_v ` computations for near ideal
18+ devices are more numerically stable. However, very, very near ideal
19+ resistance_series and/or resistance_shunt may still cause issues with the
20+ implicit solver (:issue: `340 `)

1022Bug fixes
1123~~~~~~~~~
1224* Remove condition causing Overflow warning from clearsky.haurwitz
25+ (:issue: `363 `)
1326* modelchain.basic_chain now correctly passes 'solar_position_method'
14- arg to solarposition.get_solarposition
15- * Fixed: `Variables and Symbols extra references not available <https://github.com/pvlib/pvlib-python/issues/380 >`_
27+ arg to solarposition.get_solarposition (:issue: `370 `)
28+ * Fixed: `Variables and Symbols extra references not available
29+ <https://github.com/pvlib/pvlib-python/issues/380> `_ (:issue: `380 `)
1630* Removed unnecessary calculations of alpha_prime in spa.solar_position_numpy
17- and spa.solar_position_loop
18- * Fixed args mismatch for solarposition.pyephem call
31+ and spa.solar_position_loop ( :issue: ` 366 `)
32+ * Fixed args mismatch for solarposition.pyephem call
1933 from solarposition.get_solarposition with method='pyephem'
2034 arg to solarposition.get_solarposition (:issue: `370 `)
2135* ModelChain.prepare_inputs and ModelChain.complete_irradiance now
2236 correctly pass the 'solar_position_method' argument to
2337 solarposition.get_solarposition (:issue: `377 `)
2438* Fixed usage of inplace parameter for tmy._recolumn (:issue: `342 `)
