Changes in version 0.6.2 (2026-10-16)                  

  - Fix wrong mixed-integer solutions from ECOS_csolve() with boolean
    variables on platforms where char is unsigned (Linux aarch64).
    Reported by the r-devel linux-arm64 checks.

                 Changes in version 0.6.1 (2026-02-18)                  

  - Fix UBSan error (misaligned pointer from REAL() on zero-length
    vector) in build_result() when no equality constraints are present
    (p = 0). Reported by CRAN M1 SAN checks.

  - Add multi-step solver lifecycle API: ECOS_setup(), ECOS_solve(),
    ECOS_update(), and ECOS_cleanup() allow re-solving problems with
    changed numerical data (same sparsity structure) without repeating
    symbolic analysis. Workspace held in an external pointer with GC
    finalizer; user data vectors are duplicated to prevent corruption
    from ECOS in-place equilibration.

  - Switch R-level error messaging from stop() to cli::cli_abort() with
    inline markup ({.arg}, {.cls}, {.code}, {.field}). The cli package
    is now in Imports.

  - Add lifecycle tests (10 tests covering setup, solve, update,
    cleanup, and helper functions).

                        Changes in version 0.5-7                        

  - Switch ECOS submodule to fork (bnaras/ecos, r-patches branch);
    remove ecos-2954b2a-changes/ overlay and simplify Makevars.

  - Fix copy-paste bug in A matrix validation (inherits(G,...) was used
    instead of inherits(A,...)).

  - Enable dimension consistency check (sum(q) + l + 3*e == nrow(G)).

  - Signal an R error instead of returning silent NULL when ECOS_setup
    or ECOS_BB_setup fails.

  - Fix R_init function name to match package name (R_init_ECOSolveR).

  - Narrow import(methods) to importFrom(methods, as).

  - C solver fixes: wright omega Taylor series bug, NULL dereference and
    memory leaks in ECOS_BB, integer truncation in pfloat rounding,
    missing include guards, printf replaced with Rprintf.

  - Cherry-pick upstream NaN bail-out (PR #181) and ECOS_updateData
    NULL-safety fix (PR #185) from ECOS develop branch.

  - Add unit tests for ecos.control, make_csc_matrix, dimension
    validation, and plain-matrix A handling. Fix test-bb.R to
    namespace-qualify Matrix::sparseMatrix.

                        Changes in version 0.5-6                        

  - Clean up matrix coercions

                        Changes in version 0.5-5                        

  - Fix CRAN issues re: prototypes.

                        Changes in version 0.5-4                        

  - Address the issue caused by Matrix 1.3.x: Force coercion to
    "dgCMatrix" if not so. Make corresponding change in vignette.

                        Changes in version 0.5-3                        

  - Fix some awful cut-and-paste error in R/ecos.R
  - Address edge case for ECOS_BB when G is NULL.

                        Changes in version 0.5-2                        

  - Fix compilation issue on Ubuntu by modifying Makevars and
    Makevars.win to use Rscript call to R.home() to figure out include
    path. (Issue 5)

                        Changes in version 0.5-1                        

  - ECOS source fix for header glblopts.h that defined ECOS_NAN using
    portable R version R_NaN and R_PosInf. This caused the convolution
    example in CVXR package to fail on 32-bit platforms.

  - Added a convolution test to be specific.

                  Changes in version 0.5 (2019-03-20)                   

  - ECOS update: Synced underlying library to version 2.0.7.

  - Removed import of Matrix package, added slam interface,
    contributions from Florian Schwendinger.

  - Tests: Added a number of unit tests based on base C library.

                  Changes in version 0.4 (2018-02-18)                   

  - ECOS_csolve assumes A and G as NULL if any dimension is 0
  - The dims list is now coerced to integer immediately upon entry to
    ECOS_csolve
  - ECOS library sources updated to version 2.0.5.

                  Changes in version 0.3 (2017-05-16)                   

  - Updated Readme
  - Allowed empty vector c, per Anqi’s request

  - Registered .Call entries
  - Changed Anqi’s email

                  Changes in version 0.2 (2015-11-27)                   

  - Added system requirement of GNU makefile
  - Improved the description of the package
  - Checked more carefully on Linux, MacOS, and Windows

                 Changes in version 0.1-1 (2015-11-25)                  

  - First version, thought I had it right for all platforms, but quite
    wrong.
