The focus of this release was to complete the transition to the variable-precision decimal code. The full regression test suite was restored, with only two tests still failing (complex `asin` and `asinh`). The two missing functions, `Gamma` and `LogGamma`, were implemented. This also exposed many bugs that were fixed. New features: * `NumberedVariables` setting to allow `0 STO` to ease RPN transcoding (#690) * `ClearStack` (CLEAR) command * Variable-precision `gamma` and `lgamma` functions (#710) Bug fixes: * Do not leave bad expression on stack after error (#663) * Reject unit conversion between undefined units (#664) * Accept names of menus on the command line (#669) * tests: CLEAR clears stack and errors (#672) * The `:` characters now starts a tag on empty command line (#673) * Do not evaluate tagged objects too early (#674) * test: Entry and editing of equations (#677) * test: `type` returns negative values in "detailed" mode (#678) * Run loop end pointer not GC-adjusted for last allocated object (#679) * Do not erase alpha indicator when clearing busy cursor (#680) * Do not emit trailing space when rounding `1.999` to `2.` (#687) * Allow expression rewrites to deal with `pow` (#694) * Reject `«` character in symbols and commands (#695) * Rendering of spacing for decimal numbers (#699) * Improve precision of `atan` function * Rendering of `+` and `-` operators in compatibility modes (#700) * Rounding of decimal numbers no longer generates bad characters (#702) * No longer error out rendering symbolic complex (#703) * Parse complex numbers correctly inside equations (#704) * Ensure `sqrt(-1)` has a zero real part (#705) * Do not drop last digit of decimal subtraction (#706) * Evaluate expressions during expression pattern matching (#708) * `LastMenu` executes immediately while editing (#711) * Add back missing angle glyphs in font (#712) * Return correct angle quadrant for `atan2` (#715) * `Get` no longer rejects arrays as index values (#718) * `Get` returns correct error for bad argument types (#718) Improvements: * Update `.gitignore` entry * Automated testing of setting flags (#657) * Automated testing of non-flag settings (#670) * Test fixed-base based numbers using HP-compatible lowercase notation (#675) * Test fraction rendering using fancy digits (#676) * Add test for "compatible" variant of `type` command (#678) * test: Recover from error during data entry (#681) * Increase default `MaxNumberBits` to 4096 (#686) * tests: Add test for cube root of -8 (#685) * tests: Data entry for `Σ`, `∏` and `∆` (#689) * Restrict `STO` to names, natural numbers and specific IDs (#688) * doc: Document flas file access for `STO` and `RCL` (#691) * list: Optimize iterators to avoid copies (#692) * tests: spacing-independent testing of structure rendering (#693) * tests: adjust test suite for variable-precision decimals (#696) * tests: Automatically exit if `-T` option is given (#697) * tests: Check we don't accept `.` as meaning `0.` for RPL compatibility * Add `modulus` alias back for `abs` (#707) * Improve convergence speed and accuracy for logarithms * Add `decimal::make` to minimize risk of sign errors * Display stack level at top of stack level, not bottom (#709) * Improve complex `sqrt` accuracy on real axis (#714) * tests: Test decimal functions at full 34 digits precision (#716) * Complex `sqrt` and `cbrt` with full precision (#717) * tests: Take into account additional expression simplifications Signed-off-by: Christophe de Dinechin <christophe@dinechin.org>

Validate all the various decimal functions with full precision output as given by
calcor Wolfram Alpha.This may require various functions to increase intermediate precision.
