Figure 1. Capacitance variation vs. DC voltage for select 4.7µF capacitors. Note, first, that as the package size increases, the capacitance variation with applied DC voltage decreases, and substantially. A second interesting point is that, within a package size and ceramic type, the voltage rating of the capacitors seems often to have no effect.

When operating at the low-temperature limit, the capacitance of aluminum electrolytic capacitors with a low temperature rating of -550C declines by less than 20%. The resistive component of an equivalent series circuit of a capacitor is referred to as the equivalent series resistance (ESR).
For long periods of storage keep capacitors at cool room temperatures and in an atmosphere free of halogen gases like chlorine and fluorine that can corrode aluminum. Storage temperature ranges are from –55 ºC to the upper limit of the operating-temperature ranges. Sources: Capacitor Selection Guide - KEMET (.PDF)
They and most capacitors DO have a maximum temperature rating. Most are rated to 85 C but for SMPS and other power devices you may need to buy 105 C rated versions. An 85 C capacitor exposed to 100 C will have a short life. It may dry up and do nothing, or pressure build-up may make it go BANG.
When operating at -400C, low-voltage aluminum electrolytic capacitors with a low temperature rating of -550C exhibit a capacitance loss of between -10% and -20%. Capacitance loss for high-voltage capacitors can be up to 40%.
3.4 The capacitor cells shall be impregnated with a biodegradable, environmentally friendly and non-toxic dielectric fluid. 3.5 The capacitor cells shall be suitable for continuous operation over a temperature range of -400C to +700C. 3.6 The capacitor cells shall be of “low loss” design with losses not to exceed 0.5 watts per KVAR.
