b. 454

composition: Op. 16, Rondo in E♭ major

..

In GE1, the engraver overlooked the  lowering c4 to c4. The mistake was corrected in GE2.

b. 454

composition: Op. 11, Concerto in E minor, Mvt III

No indication in FE (→EE)

Viol. in GE

[Tutti] suggested by the editors

..

The addition introduced in GE must be arbitrary and, what is more, untrue, since this two-bar insert is performed by the entire orchestra and not only by strings. The reviser added a 'Viol.' indication, which was probably influenced by the situation in bar 443, in which he had already added such a 'Viol.' following its three-time appearance in bars 412, 421 and 429. In the main text, we suggest the indication 'Tutti,' compliant with the actual cast.

b. 455-463

composition: Op. 21, Concerto in F minor, Mvt III

..

While proofreading FE (→EE), Chopin changed – just like in analogous bars 415 and 423 – d2 to e2 featured on the penultimate quaver in bars 455 and 463.

b. 455

composition: Op. 21, Concerto in F minor, Mvt III

..

In A the only accidental before the 1st chord in the R.H. is the cautionary  before e2. From the musical point of view, the version with dwould be possible, yet a comparison with analogous bar 425 and a  of d3 added – probably by Chopin – already in GE1 (→FEEE, →GE2) prove Chopin's mistake. Chopin committed the same mistake in a similar context in bar 423.
In the main text we omit the unjustified  before e2.

b. 455-456

composition: Op. 21, Concerto in F minor, Mvt III

3 long accents in A

3 short accents in GE

2 short accents in FE (→EE)

..

The notation of the three subsequent accents is unambiguous in A – they are 3 long accents. In spite of this, GE reproduced them as short accents, whereas in FE (→EE) the third of them was overlooked.
