+
+ Bug was introduced in version:

+
+ Bug was fixed in version:
+ 4.2.0.0
+
+ Description:
+ In version 2.0.1, a new run-time element "EL_AMOEBA_DROPPING" was added,
+ but the property "can fall" was missing, which caused some levels to be
+ unsolvable. This was fixed in version 4.2.0.0.
+
+ Affected levels/tapes:
+ An example for a tape that was fixed by this bugfix is tape 029 from the
+ level set "rnd_sam_bateman".
+ The wrong behaviour will still be used for all levels or tapes that were
+ created/recorded with it. An example for this is tape 023 from the level
+ set "rnd_gerhard_haeusler", which was recorded with a buggy game engine.

+ the special case of tapes recorded with game (not engine!) version 2.0.1 or
+ above, but before it was known that this change would break tapes like the
+ above and was fixed in 4.2.0.0, so that the changed behaviour was active

+ that are affected are some tapes from the level set "Walpurgis Gardens" by
+ Jamie Cullen.
+ The second condition is an exception from the above case and is needed for
+ the special case of tapes recorded with game (not engine!) version 3.1.0 or
+ above (including some development versions of 3.1.0), but before it was
+ known that this change would break tapes like the above and was fixed in
+ 3.1.1, so that the changed behaviour was active although the engine version
+ while recording maybe was before 3.1.0. There is at least one tape that is
+ affected by this exception, which is the tape for the one-level set "Bug
+ Machine" by Juergen Bonhagen.

+ Summary of bugfix/change:
+ Fixed handling for blocking the field the player leaves when moving.
+
+ Fixed/changed in version:
+ 3.1.1
+
+ Description:
+ Before 3.1.1, when "block last field when moving" was enabled, the field
+ the player is leaving when moving was blocked for the time of the move,
+ and was directly unblocked afterwards. This resulted in the last field
+ being blocked for exactly one less than the number of frames of one player
+ move. Additionally, even when blocking was disabled, the last field was
+ blocked for exactly one frame.
+ Since 3.1.1, due to changes in player movement handling, the last field
+ is not blocked at all when blocking is disabled. When blocking is enabled,
+ the last field is blocked for exactly the number of frames of one player
+ move. Additionally, if the player is Murphy, the hero of Supaplex, the
+ last field is blocked for exactly one more than the number of frames of
+ one player move.
+
+ Affected levels/tapes:
+ (!!! yet to be determined -- probably many !!!)
