+The JDK 11 Updates project uses two GitHub repositories.
+Updates are continuously developed in the repository [jdk11u-dev](https://github.com/openjdk/jdk11u-dev). This is the repository usually targeted by contributors.
+The [jdk11u](https://github.com/openjdk/jdk11u) repository is used for rampdown of the update releases of jdk11u and only accepts critical changes that must make the next release during rampdown. (You probably do not want to target jdk11u).

+For more OpenJDK 11 updates specific information such as timelines and contribution guidelines see the [project wiki page](https://wiki.openjdk.org/display/JDKUpdates/JDK11u).

+# From Paul Eggert (2024-05-24):
+# The London Gazette, 1903-04-03, page 2245, says that
+# as of 1903-03-03 a time ball at the port of Lourenço Marques
+# (as Maputo was then called) was dropped daily at 13:00:00 LMT,
+# corresponding to 22:49:41.7 GMT, so local time was +02:10:18.3.
+# Conversely, the newspaper South Africa, 1909-02-09, page 321,
+# says the port had just installed an apparatus that communicated
+# "from the controlling clock in the new Observatory at Reuben Point ...
+# exact mean South African time, i.e., 30 deg., or 2 hours East of Greenwich".
+# Although Shanks gives 1903-03-01 for the transition to CAT,
+# evidently the port transitioned to CAT after 1903-03-03 but before
+# the Portuguese legal transition of 1912-01-01 (see Europe/Lisbon commentary).
+# For lack of better info, list 1909 as the transition date.

+# Today the Congress of Paraguay passed a bill to observe UTC-3 permanently....
+# The text of the bill says that it would enter into force on the first
+# Sunday in October 2024, the same date currently scheduled to start DST....
+# https://silpy.congreso.gov.py/web/expediente/132531
+# (2024-10-14):
+# The president approved the law on 11 October 2024,
+# and it was officially published on 14 October 2024.
+# https://www.gacetaoficial.gov.py/index/detalle_publicacion/89723
+# The text of the law says that it enters into force on the first
+# Sunday in October 2024 (6 October 2024).  But the constitution
+# prohibits retroactive effect, and the civil code says that laws
+# enter into force on the day after their publication or on the day
+# that they specify, and it also says that they don't have retroactive
+# effect.  So I think that the time change on 6 October 2024 should
+# still be considered as DST according to the previous law, and
+# permanently UTC-3 from 15 October 2024 according to the new law....
