                 Changes in version 0.1.7 (2023-01-16)                  

    o   fixed bug in is_totally_unimodular() (thanks to Divya Padmanabhan
	for the bug report)

    o   replaced occurrences of sprintf() with snprintf() as of new
	CRAN policy (thanks to Brian Ripley for the head's up)

                 Changes in version 0.1.6 (2022-06-16)                  

    o   subst_values() gains 'eps' argument and by default substitutes
	zero for all values x with |x|<=1e-8.

                 Changes in version 0.1.5 (2021-04-29)                  

    o   Fix in 'compact': pairs of inequations were not detected correctly.

    o   Added 'rmarkdown' to 'Suggests' as requested by CRAN

                 Changes in version 0.1.3 (2019-12-05)                  

    o   Updated uses of .Call to include PACKAGE="lintools" (thanks to Harm Jan Boonstra)

    o   Switched to the 'tinytest' testing framework

                 Changes in version 0.1.2 (2018-07-30)                  

    o   'compact' now removes duplicate rows from linear systems (controlled by 
	 new argument 'deduplicate').

    o   bugfix: in some cases, 'compact' would return the wrong value for 'neq'.

    o   bugfix in 'compact': cases of differing b_i and b_j, Ai. + Aj. = 0, and both
	 of type '<=' would incorrectly be combined to an equality.

                Changes in version 0.1.1.4 (2017-06-06)                 

    o   bugfix in 'eliminate': faulty update of H matrix led to crashes in some cases.

    o   bugfix in 'compact': ins some cases the wrong neq was returned.

                Changes in version 0.1.1.3 (2017-02-23)                 

    o   bugfix in ranges. Crashed on some cases where matrices w/zero rows were created.

    o   native routines now registered as requested by CRAN

                Changes in version 0.1.1.1 (2016-03-04)                 

    o   new function 'is_totally_unimodular'

    o   new function 'ranges' computes variable ranges implied by a system of (in)equations

    o   eliminate gains argument 'eps' to control numerical accuracy

    o   deprecated sparseConstraints in favor of the more consistent name sparse_constraints

    o   bugfix: pinv crashed on matrices with a single s.v. 

    o   bugfix: eliminate would sometimes report the wrong number of (in)equalities

    o   bugfix: eliminate sometimes crashed because of a mismatch in colnames of history matrix

                 Changes in version 0.1.0 (2016-01-22)                  

    o   Initial release
