+== [31.03.2025] ==
+  * Re-processed ''rlut'' and ''rlutcs'', during the correction of 2022.09.21 there was an error in the timestep increment for some files (it went backwards).
+\\
+== [28.03.2025] ==
+  * Back extended ''ps'' to 1940.
+\\
+== [28.02.2025] ==
+  * Added ''orog'' invariant variable.
+  * Removed ''sic'' from invariant variables.
+\\
+== [19.11.2024] ==
+Added potential evapotranspiration ''evspsblpot'' at ''1hr'' and ''mon'' time frequencies.
+\\
+== [17.05.2024] ==
+Due to the ERA5.1 ''E1'' 2000-20006 patch, variables ''esn snm wsgsmax lspf uvb cape clwvi clivi prlsprof prcprof prsn bld hfss hfls zmla rsds rlds rss rls rst rlut tauu tauv evspsbl xgwdparam ygwdparam gwd tasmax tasmin mrro rstcs rlutcs rsscs rlscs rsdt pr prsnc prlsns'' had some missing hours in that interval:
+  * some had 2000-01-01 starting at 07 (instead of 00 or 01 depending on whether the variable was Instantaneous or accumulated),
+  * and 2006-12-31 ending at 23 instead of 2007-01-01 00 (again, depending on the type of variable).
+This missing timesteps are no longer there, the gaps have been filled with ERA5 ''E5'' data, and the daily and monthly averages recalculated accordingly.
+\\
+== [22.04.2024] ==
+Variables ''rsds, rlds, rss, pr, prsn'' had 1H 2024.03.22 information missing in original grb file. This has been amended and re-run.
+\\
+== [10.04.2024] ==
+Back-extended 2 evapotraspiration variables ''esn'' and ''evspsbl'' (''1hr'', ''mon'') from 1940 till now
+\\
 == [23.01.2024] ==
