Convex v0.14.0

Diff since v0.13.8

Changes in v0.14.0

Breaking changes

• Changes to the sign of atoms:
  • The sign of sumlargesteigs has been changed from Positive to NoSign() instead of Positive(), to allow non-positive-semidefinite inputs (#409). This has the potential
    to break code that required that sign to be positive. If you run into this problem, please file an issue so we can figure out a workaround.
  • The sign of eigmin and eigmax has been changed from Positive to NoSign() (#413). This is a bugfix because in general eigmin and eigmax do not need to return a positive quantity (for non-positive-semidefinite inputs). Again, this has the potential to break code that required that sign to be positive. If you run into this problem, please file an issue so we can figure out a workaround.
• Removal of deprecations:
  • lambdamin and lambdamax has been deprecated to eigmin and eigmax since Convex v0.13.0. This deprecation has been removed, so your code must be updated to call eigmin or eigmax instead (#412).
  • norm(x, p) where x is a matrix expression has been deprecated to opnorm(x,p) since Convex v0.8.0. This deprecation has been removed, so your code must be updated to call opnorm(x, p) instead (#412). Currently, norm(x,p) for a matrix
    expression x will error, but in Convex.jl v0.15.0 it will return norm(vec(x), p).
  • Convex.clearmemory() has been deprecated and unnecessary since Convex v0.12.5. This deprecation has been removed, so if this function is in your code, just delete it (#412).
  • vecnorm(x, p) has been deprecated to norm(vec(x), p) since Convex v0.8.0. This deprecation has been removed, so your code must be updated to call norm(vec(x),p) instead (#412).
• Other changes:
  • Convex.DCP_WARNINGS was introduced in Convex v0.13.1 to allow turning off Convex.jl's DCP warnings. This has been removed in favor of the function Convex.emit_dcp_warnings() (Commit 481fa02).

Other changes

• updated nuclearnorm and sumlargesteigs to allow complex variables, and allow the argument of sumlargesteigs to be non-positive-semi-definite (#409). Thanks to @dstahlke!
