v9.8.1: PROJ 9.8.1

Warning

It was discovered after the PROJ 9.8.0 release that several EPSG updates introduced
after EPSG v12.033 - notably the introduction of national realizations of ETRS89
(ETRS89-XXX […] where XXX is the 3-letter ISO country code) - caused backward
incompatibilities in some workflows involving the ETRS89 CRS.

In particular, transformations between ETRS89 and national CRSs based on other
datums are known to be affected for Austria, Belgium, Catalonia, the Netherlands,
Romania, and Serbia. See #​4736 for more details.

While we intend to resume tracking the latest EPSG releases in future PROJ
versions, the safest solution identified so far to address these regressions is to
revert the EPSG related content of its database from EPSG v12.049 to v12.029,
where v12.029 was the version distributed with PROJ 9.7.1

As a consequence of this revert, the EPSG datum and CRS records introduced in
PROJ 9.8.0, which are mostly related to the new ETRS89-XXX datum and CRS, are no
longer available in PROJ 9.8.1.

Updates

• Database: Revert content from EPSG v12.049 to v12.029 (#​4741).
  See above warning for more details.

• CMake: handle deprecated SQLite::SQLite3 target in CMake 4.3 (#​4694)

Bug Fixes

• Make sure that epoch is set in more scenarios of time-dependent transformations (#​4688)

• pj_obj_create: use database context if already open for grid name resolution (#​4703)

• Chain vertical CRS transformations through intermediate same-datum vertical CRS (#​4711)
  Helps for example for EPSG:5705 (Baltic 1977 height) to EPSG:5706 (Caspian depth)
  by using intermediate operation from Baltic 1977 height to Caspian height

• gie: various fixes around crs_src/crs_dst support and bootstrap
  test/gie/epsg_grid.gie and test/gie/epsg_no_grid.gie (#​4740)
