The Spanish dictionaries installed alonside LibreOffice (version 0.8) have been updated.
2 weeks ago, the "rla-es" project published source zipped version "2.0":
It'd be great if you could update the dictionaries.
Version 2.0 is listed as “alpha” here , so perhaps it’s wise to wait a bit until they deem the new release as stable? I understand they’ve made some breaking changes (e.g.,  )…
I don't know why they targeted it as "alpha" because the changes were all straightforward.
In fact, the "breaking change" you indicated , is marked as "non-valid" ("error" in that Spanish bug-track). Issue arose because of a misunderstanding (confounding the TeX algorithm ISO codification limitations with the hyphen program implementation with no limitations, mixed altogether with some ISO-UTF misunderstandings).
Anyway, in that thread, RickyES indicate that "los complementos están ya subidos al catálogo de LibreOffice" ("the addons are already uploaded into LibreOffice catalogue") which confuses me, at least, 'cause I haven't found them in the repositoy .

Nice guess, but “error” is a Spanish word for “bug”.
Anyway, I’ve worked with one of the dictionary devs and the dictionary is now updated in LibreOffice.
